AGINCO & ROBIT: SYNERGY IN SAUDI ARABIA

Saudi Arabia has been a dominant force in the global oil market for more than 80 years. With the inevitable shift away from fossil fuels gaining pace, the country is now in the midst of a profound transformation that will diversify its oil- and gas-dependent economy.

The main goals of the future Saudi economy are outlined in the ambitious Vision 2030 program, which involves heavy investments in several sectors. One of them is tourism, which will see massive infrastructure and other construction projects in the coming years.

Another focus area is mining: Saudi Arabia is rich in a number of valuable minerals such as gold, phosphates, and bauxite, and the government is actively wncouraging foreign investments in the sector.

These developments have made Saudi Arabia an attractive growth market for global players in the industry – and Robit is no exception.

Robit took a decisive step forward early this year by signing a distribution deal for their drilling tools with Aginco, the Kingdom’s leading supplier of drilling equipment and tools. Founded in 1978, Aginco serves the mining, engineering, and construction sectors with top-of-the-range materials and extensive professional services.

Aginco seemed like the perfect match for Robit, says Robit’s Distributor Business Manager Ahmad Afridi. “Both parties saw big potential for synergy. Robit is a well-known brand in Saudi Arabia. As Aginco also represents Normet and other top brands in underground mining and construction, we have a great product portfolio to serve similar customers.”

“Aginco is also a growth company like Robit. We are excited to work together to gain a larger share in this heavily competitive market. I see major growth in the following years in mining alone”, Ahmad says.

From Aginco’s perspective, the collaboration marks a significant milestone in their mission to support Saudi Arabia’s Vision 2030 goals. Aginco’s director, Faisal Sindi comments: “We are excited to partner with Robit, a globally renowned brand in the drilling industry. This collaboration aligns perfectly with our commitment to bringing world-class products and services to Saudi Arabia. Together, we aim to contribute significantly to the Kingdom’s economic diversification and growth, particularly in the mining sector, which holds tremendous potential.”

TEST RESULTS CONVINCED BRAUTESETH TO CHOOSE ROBIT

Phalaborwa is a vast mining complex located next to the mighty Kruger National Park in the northeast corner of South Africa. It is host to several valuable minerals such as copper, phosphate, zirconium, iron, and vermiculite.

One of the entities within the Phalaborwa complex is the Foskor open-pit phosphate rock mine. Phosphate is a critical mineral in fertilizers. Before the foundation of the Foskor mine in the 1950s, South African agriculture depended on imported phosphate rock. Today, largely thanks to Foskor’s success, South Africa exports phosphate fertilizers worldwide.

Drilling and blasting at the Foskor mine in Phalaborwa is operated by Brauteseth Blasting, a family business founded in 1983 in the KwaZulu-Natal (KZN) province of South Africa. The company started as a small-scale civil blasting company catering to KZN’s construction industry. In forty years, it has grown into a major national player, contracting to more than 20 quarries, five large-scale mining operations, and several construction sites.

Brauteseth has built its success on two cornerstones: a highly skilled, motivated staff and continuous investment in top-of-the-range technology and equipment. This focus on quality tools extends to consumable parts as well.

Brauteseth Blasting operates eight drill rigs at the Foskor mine. As their consignment agreement with their then-supplier of DTH hammers and drill bits was ending in late 2023, Robit SA approached Brauteseth, requesting a performance test of Robit’s and the then-current supplier’s DTH tools.

The extensive testing period started in October 2023 and was completed in February 2024. Robit’s tools included the D65 QL60 3½” API REG blast-hole hammer and 165 mm QL60 Flat Face blast-hole bits.

“The test results were clear: Robit’s tools outperformed the competition in terms of penetration rate and cost-per-meter”, says Duane Kukard, Area Sales Manager at Robit SA.

Convinced by the tests, Brauteseth Blasting signed a consignment agreement to supply their drill rigs at the Foskor mine with Robit’s DTH 6″ equipment.

Since May 2024, all eight of Brauteseth’s rigs in Phalaborwa have been drilling blast holes with Robit’s tools – now with increased efficiency and profitability.

CERRO CORONA: TESTING IN THE SHADOW OF A PANDEMIC

Thanks to its rich gold deposits, the Cajamarca region in northern Perú has been home to gold mines since the Inca times. One of the current mines is Cerro Corona, where Robit recently became the preferred supplier of DTH drill bits.

Cerro Corona mine, owned by Gold Fields Inc, is located on the eastern slope of the western Andes, some 80 km north of the regional capital of Cajamarca. The open pit mine is expected to produce some 2.1 Moz (about 60,000 kg) of gold and 407 kt of copper in concentrate over its 15-year mine life.

The rich gold deposit is hosted by diorite porphyry, an extremely hard rock embedded in limestone. MUR-WY, the drilling contractor at Cerro Corona, uses the so-called pre-splitting method, where closely spaced holes are drilled and lightly charged, causing fractures that isolate the gold-bearing rock from the surrounding rock mass. Successful pre-splitting requires very straight holes, and, as always, this should be achieved with optimal cost, penetration rate, and tool lifetime performance.

Robit believed their tools might improve productivity, so they contacted MUR-WY in 2021 to arrange test drillings for 5” DTH bits at Cerro Corona. Test drilling is typically a very hands-on type of work where you monitor and make adjustments on the spot with the contractor. However, the COVID pandemic complicated things.

“In 2021, access to the mine was heavily restricted, so we had to get creative with MUR-WY to follow up on the tests. We ended up monitoring the performance remotely through WhatsApp videos and messages”, says José Luis Cisneros, General Manager of Robit SAC.

Luckily the restrictions were eventually lifted, and Robit’s Regional Sales Manager, Martín Rodriguez, was able to revisit Cerro Corona and conclude the tests, which proved highly successful.

“On average, compared to the tools they had used, we reached 20 to 25% better yields with our DHD340 Flat Face Premium bits and 40 to 50% better with our D45 HD hammers.

“We detected several ways to improve productivity. Not only did Robit’s components perform better, but a key factor is also the service we can provide. We are now the preferred supplier for DTH consumables at Cerro Corona. There are still challenges to tackle, but we will work with our strategic partners from MRU-WY to articulate better ways to approach their needs and increase security regarding the project’s required logistics”, Martín says.

PRODUCT DEVELOPMENT THROUGH COLLABORATION

When developing products for use under several conditions, it is vital to consider the experiences of people using the products. In modern times, it is possible to simulate all sorts of conditions in a lab environment or using computer models. But these can often only give an indication of the product’s performance in the real world, whereas those working in the conditions set by said real world can tell you a lot more.

For the above reasons, Robit has a long tradition of working with its distributor partners and end-customers alike regarding product development. The end-users know their equipment and circumstances better than anyone, so they can often test new and existing products under true-to-life conditions. This way, one can ensure that the test results correspond to the products’ actual performance and durability capabilities.

Collaborating towards better efficiency
One of Robit’s long-term test partners is Stevin Rock, which operates a limestone quarry in the United Arab Emirates with a fleet of Down the Hole (DTH) machinery. They have been using Robit-manufactured DTH tools since 2016. Stevin Rock has been using the full suite of Robit’s drilling consumables, with a 4″ hammer as their workhorse of choice and adaptors, drill tubes, and 110 mm and 127 mm bits aiding the work.

The initial contract was made after Robit succeeded in the trials at the Stevin Rock quarry. Robit’s products triumphed with a longer life span and lower cost per meter than the competition at the time. While some alternatives provided a higher penetration rate, this benefit was trumped by the higher number of breakages it brought. They decided to go with Robit, which offered known products that provided conclusive and consistent high performance.

In the years since the initial contract, Robit has proven itself as the right choice with an excellent overall life span of products, a high level of service, and numerous supporting drill master visits. Indeed, these visits have been the core of the support and collaboration towards the customer. A Robit drill master has been visiting the site on support duties a couple of times a year to help Stevin Rock optimize their processes. In addition, Robit and their distributor partner DeltaCorp Global have conducted on-site practical and theoretical training sessions for the operators and mechanic teams on hammer assembly, preventative maintenance, bit wear, failure modes, and best drilling practices.

Robit always aims to find the best possible distributors for each region; the goal is to find those who understand the local market, culture, and general thinking. In DeltaCorp Global, Robit has one such winner. During the years, DeltaCorp has fostered a very close working relationship with Stevin Rock. This allows them to consistently offer timely and relevant support for the customer across their organization. DeltaCorp’s representatives conduct at least one visit each week to one of Stevin Rock’s three sites. The purpose of the visits ranges from stock deliveries to management meetings, where product quality and life span, as well as stock levels and forecasts, are assessed. While on-site, the representatives will also visit the drill rigs to receive direct feedback from the drill operators. On top of all that, the DeltaCorp representatives maintain constant communication with Stevin Rock’s site management, working swiftly in the event any concerns should be raised, such as a sudden need for urgent deliveries, an unforeseen breakage, or some other operational problem.

Thanks to continuous support, Stevin Rock has improved the results they get with their equipment even further. When the initial contract started in 2016, the average life span of a drill bit was 2,000 meters, with hammers reaching approximately 8,000 meters. With all the training given to the personnel to help them make the most out of their tools, the efforts to optimize the drilling processes, as well as the product improvements from Robit’s Engineering and Production teams that based on the customer’s feedback, the average bit life span has extended to 4,500 meters, with the hammers regularly exceeding 25,000 meters.

While the durability and solid performance of the drilling consumables first made Stevin Rock give Robit’s drilling tools a chance, they have since gotten several more reasons to stick to their decision. And while they have been periodically testing multiple competing products, they have not had a reason to switch.

“We have been using Robit’s products for years and cannot fault their performance or service. We run an open tender every two years, and they always come out on top. Robit’s commitment to collaboration and continuous improvement is their great strength. However, their local Distribution Partner is also strong; with their reliable supply chain management and quick reaction times, a solution is always available to us 24/7.”

Collaboration as the basis for product development
During their years working with Stevin Rock, Robit has been conducting numerous tests on many hammers and bits. All these tests have aimed to increase the life span of the products, as well as their performance, with minimal downtime and breakages so that the customer can reduce their drilling costs to the minimum. Tests carried out with customers have been at the heart of Robit’s product development process. Those trials have led to discoveries and breakthroughs that have guided the designs of their latest products, with the upcoming H-series hammers as a good reference point.

The new H-series hammers have been designed with performance and versatility as their guiding principles. The goal was to provide customers with a hammer range that they could utilize in different environments with minimal breakages and maximized utility for each operator’s circumstances. Customer feedback led Robit to develop a new modular design, offering increased flexibility and adaptability to varying conditions. With a few simple changes in the assembly of the hammer, the user can customize it for their needs; whether one wants to run them with improved productivity in mind or needs to be able to use a lower capacity compressor, the H-series hammers can be modeled to suit these requirements.

In practice, the modular design allows Robit to offer four hammers in one base design. The assemblies vary between high power and low volume, as well as foot valved and tubeless. Thus the following variations are available: high power with a foot valve, high power tubeless, low volume with a foot valve, and low volume tubeless. The high-power assembly offers high blow energy and air volume, resulting in a fast penetration rate and is suitable for deep-hole drilling. On the other hand, the low-volume assembly provides lower blow energy and air consumption, which are ideal for soft ground while keeping the hammer energy efficient.

As an example, Stevin Rock was looking for a faster drilling hammer to improve the potential productivity. Robit provided them with two assemblies of the new H-series models with differing internal arrangements to control the airflow, one with low air volume and the other with high air volume. These new hammers were to be tested against the tried-and-true D45 hammer from Robit’s older hammer range. The tests showed a considerable, consistent improvement across the board. The penetration rates went up in all tests, with the smallest increase at 14% and the most significant improvement at 30%. The highest penetration rate reached during the tests was 63.18 meters per hour. These results also correlated with those seen in earlier trials, ensuring the validity of the results.

With the new hammer range, Robit wants to bring more options to the market while still guaranteeing high performance. Because if one thing has become crystal clear during their collaboration with their customers, no two drill sites are the same. For this reason, they will make sure to let their customers’ and distribution partners’ voices be heard when developing new products and improving on the old ones.

A NEW STAR IN THE MEXICAN MARKET REPRESENTS ROBIT

Peñasquito Mine, located in the State of Zacatecas in Central Mexico, is the second-largest silver mine in the world and also a major producer of gold, lead, and zinc. The giant has been successfully served by a fresh partnership between a new dynamic distributor and Robit.

The scale of operation at Peñasquito is so massive that it’s more like a small city than just an open-pit mine, with its own airport, a 1,900-bed camp with full dining, laundry and recreational facilities, and even a radio station. Opened in 2010, it currently produces some 31 million ounces, or almost 900 tons, of silver per year.

Mining is a thriving industry in Mexico, with several distributors competing over their share of the drilling consumable market. Peñasquito Mine is owned by Newmont, the world’s largest gold mining corporation. This did not stop Marlous Supplies and Services, a newcomer in the field, from landing a distribution deal for Robit DTH tools with Newmont.

Marlous was founded in the spring of 2020 by Martín Ocaño, who has an accomplished track record in the business.

“I have dedicated 24 years to the commercialization of products and services, in mining and public and private companies. For years I had been working on the idea of forming a company dedicated to supplying different products to the mining industry”, Martín says.

“Our key strength against the competition is that we focus completely on giving good attention and service to our clients, always covering their needs, interests and concerns, including after-sales. This has distinguished us and helped us enter and gain ground in the toughly competed mining market.”

In the search for a reliable supplier for drilling tools in their portfolio, Marlous decided the best option was Robit, given their experience and product quality. In the case of Newmont Peñasquito, Marlous was in the right place at the right time.

“Newmont’s main supplier of drilling tools was failing to deliver products in time. We had a similar product available, so we were able to help them out, and from then on we were allowed to start serious testing”, Martín recalls.

Currently, Marlous is supplying a major part of the DTH drilling tools used at Peñasquito. These include Robit D88 and WH4 hammers as well as QL80 and TD40 drill bits.

A key factor in their success at Peñasquito has been the technical personnel working on-site in close cooperation with the Newmont staff. This includes monthly meetings where the results of the previous month are analyzed and points of improvement can be identified.

“We are always open to feedback and encourage our customers to comment on any detail, anomaly or possible improvement. They appreciate it when their comments and observations are taken into account and implemented as soon as possible”, says Martín.

Still a young and small company, Marlous has already established a firm foothold in the Mexican mining sector. Growing steadily, the company is building on a balanced synergy between the quality of products and impeccable customer service.

GROUNDBREAKING DTH CONTRACT IN PERU

Rich in copper, silver, gold, and lead reserves, Peru is a global giant in the mining industry. Iron ore is also a significant export, although known deposits are limited to a single region.

Antonio Raimondi was an exceptionally versatile scientist. Born in Milan, Italy in 1826, he emigrated to Peru in 1850. A year later he became a professor of natural history at the National University of San Marcos in Lima. In the following years, he founded a medical school and a chemistry department there. Raimondi was also a passionate geographer, traveling extensively across the country conducting geological, botanical, and zoological studies. It was on one of these journeys that he discovered a vast iron ore deposit in the Marcona District in the Nazca province, some 500 km south of Lima, in 1870.

It wasn’t until the 1950s that the exploitation of iron ore in Marcona began. Since 1992 the open pit operation has been run by the Chinese-owned company Shougang Hierro Perú, during which time the production of iron has grown sixfold.

A large share of the drilling and earthmoving operations at Shougang Hierro Perú is conducted by Cosapi Mineria, a subsidiary of Cosapi S.A., one of Peru’s biggest construction and engineering companies. Cosapi Mineria specializes in massive earthworks and the development of open pit mines.

An open pit operation typically makes extensive use of Down-the-Hole tools for pre-split and buffer drilling. That’s why Shougang Hierro Perú was an attractive target for Robit SAC to approach with their offering.

“The iron deposit at Shougang Hierro Perú consists of very hard and abrasive materials. You can find competent soils with compressive strengths of 250 to 300 MPa”, says José Luis Cisneros, General Manager of Robit SAC.

“We contacted Cosapi Mineria and carried out the first test in early 2020 with 7-inch bits and a D65 hammer. Since then, we have been working ever more closely with Cosapi, providing them with material innovations to increase performance.”

“In recent months we have been working together with Cosapi in a testing process of the main DTH providers in the market. Thanks to the constant monitoring by our Assistance Engineer Kevin Salas, and the development of the right products through our DTH Sales Manager, Martín Rodríguez, we have been able to generate new ways of improving the operation and proposing drilling targets with higher standards”, José says.

The open pit operation requires a lot of double bench pre-splitting, performed with D45 HD hammers and 5-inch bits, ballistic buttons, and a convex face. The bits have obtained an average duration of 1,400 meters, and an average speed of 32 m/h.

Recently, Cosapi signed an extension contract for their operations in two of the open pits at Shougang Hierro Perú. Impressed by the tests conducted with Robit, they granted a consignment agreement, trusting Robit with 60% of the consumption of drilling tools over the competition.

“This is the first contract of consumption for DTH tools in Latin America where we will provide assistance and stock for the client’s operation, including technical service, maintenance of hammers and management of drill bits”, says José.

“We hope to show Cosapi Mineria and the market that Robit SAC has the necessary resources to keep exceeding the expectations of our strategic partners.”

DISTRIBUTION DEAL CREATING SYNERGIES IN CENTRAL ASIA

As far as mineral reserves go, Kazakhstan is in the top twenty in the world, and mining comprises almost one-third of the country’s export earnings. No wonder then that the competition in the sales of all mining-related goods, including drilling tools, is very tough. Robit secured a distribution deal with a key player in the region.

As a major global exporter of minerals, Kazakhstan benefits from its central geographical location between Europe and Asia. This is also reflected in the name of the largest company supplying machinery and equipment for mining and construction in the area: Eurasian Machinery LLP.

With more than 600 employees, Eurasian Machinery provides customers with high-quality technical services through ten centers in Kazakhstan and Kyrgyzstan. Besides being the official distributor of Hitachi Construction Machinery – their spearhead product line – they also supply the industry with machinery and equipment from a host of other high prestige global brands. As of August 2021, these include Robit.

George Apostolopoulos, Robit’s VP, Global Sales, is thoroughly familiar with the Central Asian market and sees great synergies for Robit in the exclusive distributor agreement with Eurasian Machinery.

“Eurasian Machinery have a strong reputation in the Kazakh market. They have done an excellent job with the Hitachi Construction Machinery brand and have placed themselves among the preferred suppliers for the country’s mining industry. They are present with equipment and service contracts in most of the mines in Kazakhstan and Kyrgyzstan”, George says.

“Customer satisfaction is driving their efforts and they are providing high-quality services to the industry. A high-tech Component Repair Center in Karaganda serves the purpose very well.”

“This is a very significant deal for Robit as the Kazakh mining market is among the biggest in the world. It’s the 2nd largest within our East sales area after Russia. It could provide significant leverage for our sales; big opportunities exist for our Top Hammer products both underground and surface, as well as our Down the Hole offering.”

“There is some tough competition in this market not only from the traditional players but also from low-cost suppliers. This makes it particularly important for us to have a renowned and well-represented distributor in this market”, George concludes.

NEW AFTON SWITCHED BACK TO ROBIT TOP HAMMER TOOLS

Two branches of the Thompson River run through the ruggedly picturesque landscapes of south-central British Columbia, to meet at the eastern end of Kamloops Lake. The town of Kamloops was founded there as a fur trading post 200 years ago. Today, Kamloops is a thriving city with rich copper and gold deposits nearby.

Afton mine, situated 10 km west of Kamloops, was originally an open-pit gold and copper mine, in operation throughout the 1980s and 90s. New Gold,a Canadian mining company, acquired the mine and restarted production in 2012, now as an underground mine called New Afton. Last year, New Afton produced 64,000 ounces (some 1,800 kg) of gold and about
33,000 tons of copper.

New Gold had been using Robit’s Top Hammer (TH) tools in New Afton for years. However, in early 2019, through ownership changes at the supplier, New Afton switched to another brand of TH consumables. Over the course of the year, it became evident that the performance of the TH Tools did not meet the Mines expectations. In 2020, Ryley Renneberg and Cody
MacLeod from the Sales Division of Pinnacle Drilling Products (Pinnacle), Robit’s Canadian distributor, decided it was an opportune time to reach out to New Gold.

“We arranged an in-person meeting with New Gold’s production mine manager. We listened to their problems with their new brand of TH tooling and discussed how we might be able to help out. New Gold had been happy with Robit before and they knew the production performance well, so this really helped progress things forward. It turned out to be the start of a great relationship between Pinnacle and New Gold”, Ryley reminisces.

“We reassured we could have a seamless transition and were able to support New Gold through the ramp-up period, not to mention this pandemic situation and the global supply chain crisis.”

For Robit, the first purchase order in the spring of 2021 meant a need for a serious production ramp-up of TH tools.

Says Mikko Vuojolainen, Robit’s Vice President, North America: “It’s always a critical period when a customer switches supplier. The new supplier must be able to deliver 100% availability. In this case, our TH production lines were already fully booked so we needed to get creative. We divided the products into two groups: those we can start delivering two months post order, and those we can start delivering four months post order. It worked out perfectly.”

Since August 2021, New Afton is back to using Robit’s TH tools in their underground operations. The New Afton deal can also help propel the Pinnacle-Robit business partnership forward.

“It brings us leverage into the mining industry within North America. I believe it’s going to open many other opportunities for us to challenge the ‘big three’ in the market”, says Ryley Renneberg.

SUCCESSFUL PRODUCT PERFORMANCE AND SEAMLESS COOPERATION AS A BASIS FOR FURTHER BUSINESS COLLABORATION IN OMAN

Robit is supplying consumables for development of two gabbro quarries in Khatmat Malaha, Sultanate of Oman. The tools are being supplied by Robit’s distributor, Pioneers For Mining Trading. The customer is Oman-based Al Sarh JV Int LLC.

The customer is using two drill rigs in the gabbro quarries and has just changed over to Robit drilling consumables. According to the customer, Robit consumables are performing well in the very hard and abrasive rock formation as the products are clearly cost effective in the comparison of different suppliers. The drilling consumables in use are 89 mm button bits with a thread of C51. The gabbro quarries of Khatmat Malaha are one of those toughest and challenging areas among Oman rock formation.

In addition to the good performance, Al Sarh JV Int LLC is happy with the delivery times as well as all the technical support regarding Robit drilling consumables. Pioneers For Mining Trading is maintaining a good inventory and technical engineer to meet the customer’s demands.

Al Sarh JV Int LLC has confirmed that they are pleased with the performance of Robit drilling consumables as well as the support received from Robit’s distributor, Pioneers For Mining Trading, and thus they will continue business cooperation with Robit and Pioneers For Mining Trading.

Despite the current travel restrictions due to COVID-19, the seamless cooperation between Robit, Pioneers For Mining Trading as well as the customer including continuous follow-up on Robit product quality and support, enables a strong sales development in Sohar region. Pioneers For Mining Trading has been awarded as a New Distributor of the year 2020 in Robit’s annual Distributor Days.

Dhofar Mining Company LLC. – the new satisfied user of Robit’s rock drilling consumables

Dhofar Mining Company LLC. is the manufacturers of high quality natural gypsum at present Dhofar Mining Co having a production of 1,200,000 MT per annum. Company operates including Thumrait near Salalah in southern Oman.

“We are really excited about Robit’s C45-76mm Drop Center button bit performance and penetration rate. Average life for the button bit is around 19,000 m in this Gypsum quarry, which is much more better than we have seen earlier.” says Mr. Hari Kumar, Quarry Manager.

Mr. Akhil Muralidharan, Sales Manager from Pioneers for Mining Trading company (Robit’s distributor in the Middle East) is convinced of successful cooperation with Dhofar Mining Company LLC.

World’s #1 copper producer chooses Robit

Copper mining has been a key driver of Chile’s economy for centuries. Among the country’s mining companies, the state-owned Codelco is the crown jewel. It’s the world’s leading copper producer with immense mineral reserves, and a driving force for the entire country’s development.

Codelco’s major mining sites include El Teniente, “the Lieutenant”, the world’s largest underground copper mine which has been in operation for 200 years and currently has a capacity of 400,000 tonnes.

The second largest mine is the century-old Chuquicamata, or “Chuqui”, as the locals call it. Since its open pit operations had grown increasingly uneconomic over the last years, Codelco made a huge investment switching to underground cave mining in 2019. Chuqui’s current capacity is 377,000 tonnes. Andina, the third largest mine nested at the dizzying height of 3,700–4,200 metres on the Andes, consists of the Rio Blanco underground mine and the Sur Sur open pit.

As of late 2020, Robit will be the main supplier of Top Hammer and Down-the-Hole drilling tools for Codelco’s three largest mines. This is a result of decisive cooperation between Robit and their Chilean distributor Full Safety.

Founded in 2010, Full Safety had focused on dealing in clothes and footwear for special target groups such as armed forces, law enforcement, health professionals – and the mining industry. The last-mentioned seemed like a promising sector for new business opportunities, and in 2015 they contacted Robit.

“We were looking for new strategies, and we met Robit at the right time. After consulting with them we restructured our business model over the next few years by opening a new office and recruiting sales personnel as well as drillmasters for field support. In turn, Robit offered us training and technical-commercial support on client visits, and participated in mining fairs with us”, recounts Cesar Cornejo, General Manager of Full Safety.

Getting a foot in the door of a global giant like Codelco is not a simple thing. Despite persistent efforts, discussions on arranging a comparison test to prove the quality of Robit’s consumables led nowhere. As a change of plan, Full Safety approached Astaldi, the main contractor at El Teniente – and they agreed to a head-to-head test between Robit and their then-current brands.

The February 2020 tests, involving bits, drifter rods and couplings, did not disappoint: Robit outperformed the competition by some 30% in terms of lifetime and penetration rate. A letter of certification by Astaldi opened the door to participate in a tender for Codelco. Full Safety and José Antonio Rodríguez, Sales Manager for Robit SAC, then carefully fine-tuned an offer that proved the most competitive.

This major achievement, however, is just the tip of the iceberg. The Chilean mining sector has vast growth potential for the Robit-Full Safety partnership, and several other tenders and product tests are already underway across the country.

Louhintaliike Ylimäki Oy – A specialist in large blasting operations

Louhintaliike Ylimäki Oy, headquartered in Lapua, is a family business that specialises in large-scale blasting and quarrying operations covering the areas of Pirkanmaa, Western and Central Finland and North Ostrobothnia. With more than 40 years of experience in the industry, the company guarantees its customers efficient and flexible service, helping it become one of the biggest quarrying operators in Finland.

Aatos Ylimäki founded Louhintaliike Ylimäki Oy in 1983. The company started out with rented equipment, but soon acquired its own manual drill and tractor-mounted air compressor. The company’s first contract was foundation work for a vocational school (Hervannan ammattiopilaitos) in Tampere. Over the years, the company’s fleet of equipment and number of personnel has grown. In 2012, the family company was transferred to the next generation, and since 2015 it has been headed by Matti Ylimäki.

Picture: Louhintaliike Ylimäki’s fleet includes six Sandvik open-pit drill rigs. According to Managing Director Matti Ylimäki (centre), head charger Matti Pitkäjärvi and driller Markku Viitanen, Louhintaliike Ylimäki has relied on the quality of Robit’s consumables, such as drill bits, rods and shanks, in its drilling operations for more than 20 years.

Quarrying with a large capacity
Today, Louhintaliike Ylimäki is known for carrying out large-scale blasting operations. With a staff of 20 and a fleet of 18 machines, the company performs rock extractions amounting to 7 million tonnes a year in a range of sites.
“Among our customers are aggregate suppliers, crushing companies and earthworks companies. We blast rock in open-pit mines in roughly 70 different sites every year; in recent years, we have also carried out a number of contracts for wind farms. We have numerous long-term customer relationships, which helps us in planning our operations in advance. Our services include crushing extractions and other large-scale quarrying, excavation of building foundations and road alignments, rock-breaking using a hydraulic rock hammer, per-metre drilling, rock slope scanning and hole straightness measuring,” lists Managing Director and head charger Matti Ylimäki.

Top-notch machine performance
Louhintaliike Ylimäki’s fleet of drilling equipment consists of six mid-range Sandvik drill rigs for open-pit mining and two Doosan excavators equipped with an ExcaDrill rock drilling attachment. The company also extensively uses rock-breaking equipment: 14 primarily Atlas Copco rock hammers mounted on ten 30–35-tonne excavators, most of which are from Doosan’s range. A wide array of other equipment used in quarrying contracts, from dumpers to vibration meters, is also in the company’s fleet.
Drill rigs are replaced after roughly 5 to 6 years of use; in one year, a single rig drills around 60 to 70 kilometres of holes in rock. The equipment is maintained at our own workshop in Lapua and of course we also use the equipment supplier’s maintenance services,” says Ylimäki.

Decades of co-operation with Robit Louhintaliike Ylimäki has relied on the quality of Robit’s consumables, such as drill bits, rods and shanks, in its drilling operations for more than 20 years. “Robit is a very important partner to us. As a Finnish operator, their service and products are always nearby, they listen closely to customer feedback, and perhaps most importantly for an operator of our size, their service is flexible – Sales Manager Esa-Matti Polvi is very pro-active, always on the lookout for new solutions to further enhance our operations. And of course the products are in top condition, which enables efficient drilling and well as a good price/quality ratio. Robit’s continuous product development brings better solutions to market and if we need, say, a few dozen special bits, they will be produced in Lempäälä just the way we want them and on a tight schedule,” praises Ylimäki.

A container with drilling products on site
A year ago, Robit set up a consignment stock at Louhintaliike Ylimäki’s location in Lapua.
“The products stocked in the container include all the drilling consumables we need, meaning bits, rods and shanks, as well as coupling sleeves and bit adapters, to name a few. Robit invoices us for the products we use, and we place orders to ensure the shelves are always stocked with what we need. The container itself was made to be user-friendly, so picking products and, for instance, using a forklift to lift drill rods onto the rack is easy. Drillers bring the products to the worksite with them in their vehicles, and they always have enough for one or two weeks’ worth of work on the rig,” says infrastructure engineer and head charger Matti Pitkäjärvi.
Robit’s consignment stock has significantly improved Louhintaliike Ylimäki’s logistics:
“It makes things easier for drillers when they can pick up the consumables they need from a single location straight off the shelf, without having to order them separately,” says Pitkäjärvi.

ROBIT PERFORMING WELL IN HARD ROCK FORMATION IN SOHAR, OMAN

Robit is supplying consumables for gabbro quarrying in Sohar, Oman. The tools are being supplied by Robit’s distributor, Pioneers For Mining.

Robit consumables are performing well in the hard rock formation, in the North Oman, and thus, getting positive feedback from the customer. The gabbro quarries are one of the toughest and challenging areas among Oman rock formation.

Despite the current travel restrictions, the seamless cooperation between Robit, Pioneers For Mining and the customer including continuous follow-up on Robit product quality and support, enables a strong sales development in Sohar region. 

Facts – Gabbro Quarry in Sohar, Oman 

Machine: Furukawa HCR 1200

Rock Formation: Hard and Abrasive

Button Bit Size: C45–89mm

Excellent performance with Robit button bit in Turkey

On July 2020, Robit’s Turkish distributor Guris Is Makinaları Endustri A.S. organized a drilling test at Ozkoyuncu open pit iron mine. The head-to-head test between Robit and globally well-known brand.

The test was conducted on a Sandvik DX800 Ranger with an HL700 drifter. The testing conditions were identical for each brand. The procedure was a simple wear test: To measure how deep each tool will be able to drill without sharpening or replacing. The ground condition is quite difficult and abrasive. It contains high quartzite and silica rate is around 90%. There is fragmented rock, water and spacing in ground.

We are happy to report the results. Robit C51-102 mm drop center spherical bit completed the service life at 1269 meters and this result is 300 meters better than competitor’s same design bit. Given the rock quality at mine site this is an excellent result. Customer confirmed that Robit bit were superior to the other well-known brands’ consumables.

Test Location: Ozkoyuncu Open Pit Iron Mine, Kayseri/TURKEY
Test Dates: Jul 09-14, 2020
Test Objective: Measuring performance of Robit C51-102 mm bit vs. other well known drilling consumable brand.

Top Hammer theoretical and practical training in Ecuador

Training organized by: Maqoperador S.A. (Ecuador) and Robit PLC
Objective: To give Top Hammer drilling tool customers theoretical knowhow and practical training to ensure maximum drilling performance
Location: Guayaquil, Ecuador
Date: November 22, 2019
Drill bits used: Robit HTG bit 45C76 DSR vs. a bit from another brand
Reported by: José Rodríguez, Sales Manager, Robit

Summary:

In ensuring maximum performance in Top Hammer drilling, one key element is selecting the optimal drill bit. To this end, a series of training sessions for our customers in Ecuador were organized jointly by Maqoperador, the distributor of Robit’s tools in Ecuador, and Robit.

In the theoretical part of the training we covered a wide range of topics such as drill string elements, energy flow through the drill string, correct drilling parameters, selection criteria for button bits, and total drilling costs.

For the practical training, Maqoperador arranged a visit to a quarry where the performance of two T45x76 mm bit designs was measured: a Robit Drop Centre Retrac bit vs. a bit from another brand. The other brand had overlarge 13 mm buttons whereas our bit was 11 mm. Typically customers see oversized carbides as a good feature, but our tests proved otherwise.

The difference in penetration rate was significantly in favour of Robit: 1,8 m/min vs. competitor at 1,06 m/min. In other words, Robit was faster by more than 70%.

Being able to drill faster with less effort also means a better energy flow from the drill string to the rock. This is why differences in overheating were also expected between the bits. If percussion energy is not correctly transmitted from the drill string to the rock, it will dissipate into heat, creating additional problems. Due to the overlarge buttons, the energy was not efficiently transmitted to the rock, so the competitor’s bit was overheating the shank adapter at 150 °C, while with the Robit bit, the shank adapter kept a much cooler temperature at 98 °C.

To ensure the reliability of the results, the testing was performed with the same drill rig, the same operator in the same quarry, using the same drilling parameters at a distance of 1 metre between the holes of each bit.

What was particularly rewarding for us to see was how actively the attendees participated in the training. Events like this are very rarely, if ever, arranged by other brands or distributors, so they truly add great value for our customers and help enhance the Robit brand. We will soon be organizing the same training in other parts of the world. Stay tuned!

ALL DRILL AND ROBIT: a partnership bearing fruit in Argentina

The Andes, the longest mountain range in the world, have been an abundant source of mineral riches for centuries – so much so that the largest Spanish-speaking nation in the world was actually named after a metal (argentum). Over the last ten years, the mining industry has seen a massive boom in Argentina.

Gold and copper are some of Argentina’s key mineral exports. Cerro Vanguardia, a major gold mine in the Santa Cruz province in southern Argentina, has been using Robit tools, such as Top Hammer and DTH RC, for six years. Customer satisfaction is crucial for Robit, and Juan Padilla, a senior Robit Drillmaster, knows where you need to look.

Feedback from the field

“The real challenge for us lies out in the field, in the hands of drillers and their supervisors. They work hard to achieve their goals, and my mission is to give them the best support so they can meet them”, Juan explains.

On his latest visit to Cerro Vanguardia Juan went right to the front line to hear the drillers’ feedback on Robit products. “Cerro Vanguardia is keen on continuous improvement, and it made me happy to learn that our tools continue to be an excellent option for them”, says Juan.

2018 has been a good year for Robit in Argentina, thanks to their dealer All Drill. Since its founder Ariel Fernandez was already familiar with and impressed by Robit products, the decision to partner was easy to make.

One of the new deals All Drill and Robit have signed took place in Casposo, a gold and silver mine in the San Juan province. 20 days of rigorous testing convinced the contractor of the quality of Robit’s Top Hammer tools. Cerro Negro, a large gold mine located in southern Argentina, has also opened its doors to Robit products.

Seamless teamwork

”I felt super confident about the opportunity to represent Robit exclusively in the Argentinian mining market. When you have one of the key brands in the world to offer, and you get great support from their Regional Manager Alexei Albuquerque and his team, you have all a dealer needs to close good deals”, says Ariel Fernandez.

Mining has still a lot of growth potential in Argentina, and Robit and All Drill are searching for new opportunities around the country. ”We are proud to say that Robit has become a major player in the Argentinian mining market, with very positive feedback from the end-users. This is a great foundation for planning the future and our next steps. It is a result of hard work, time investment, and trust between All Drill and Robit”, Alexei Albuquerque concludes.

TEST REPORT – Altyntau Kokshetau quarry, Kazakhstan

Tested tools: Robit DTH hammer and bits
Test location: Altyntau Kokshetau quarry, Kazakhstan
Client’s challenge: Finding an alternative for their existing QL6 DTH hammer: problems with the upper adapter not solved by the manufacturer
Reported by: Andrey Dak, General Director, LLP Robit Kazakhstan

Report:

At the site, Robit Kazakhstan has tested two QL6 DTH hammers, with 171 mm Robit DTH bits. Representatives of Robit Kazakhstan and Robit Russia as well as competitors’ technical specialists were present at the test. Each of 3 drill rigs had drilling tools from different manufacturers.

As a result, Robit hammers demonstrated excellent results, whereas the tested drill bits did not show the best performance. Therefore, Kazzinc acquired a batch of Robit hammers.

Once in operation, quality issues with the acquired DTH hammers arose: the lifetime of some of the hammers was 30 % less than expected. Lifetime expectation is set by the quarry; we accepted the challenge.

We took a customer-oriented approach and invited a technical specialist from Australia to Altyntau Kokshetau. In addition, two upgraded hammers and redesigned 171 mm DTH bits were sent. Using all the test data, we strove to manufacture the best fit for the customer’s ground conditions. The changes mostly concerned the hammer’s cylinder, make-up assembly, the DTH bit’s check valve and buttons. A second test supervised by our local Robit expert was conducted.

Eventually, thanks to our group’s teamwork and our desire to provide the best service, the performance became excellent again – even exceeding the lifetime expected by the contract. The upgraded DTH bits also showed good results, reaching their expected lifetime. The deal was secured.

Kazzinc decided to continue using Robit drill consumables. Starting from the beginning of 2019, a new contract for a batch of DTH hammers and DTH bits was signed.

TEST REPORT – Greenbushes, WA, Australia

Tested tools: Robit C51 bits, rods and shanks
Test location: Greenbushes, WA, Australia
Test date(s): Since May 2018
Client’s challenge: Top Hammer drill bit performance in the hard ground conditions of a lithium mine
Reported by: Mark Thwaits, Technical Sales Representative, Robit Australia

Report:

We began trialling at Greenbushes, the world’s largest lithium mine, in the spring of 2018. They are currently using our C51 Retrac bits monthly, principally the 115 mm Drop Centre Retrac (DSR) and Flat Face (FF).

Through frequent site visits we have developed a very positive relationship with our customer where information has become a two-way street. For example, it was our suggestion to try the DSR bit as a substitute to the FF, as we had seen it perform extremely well in similar conditions elsewhere.

We have secured their TH bit business off the strength of Robit’s bits. The life and performance of our bits has been praised by the client. They easily outlast the competition – and with the extremely hard and abrasive ground associated with lithium mines, the increased life of Robit bits has been greatly appreciated.

In today’s intensely competitive market, Australian drilling contractors have become far less inclined to sign contracts, preferring to give monthly business to the supplier who performs and provides value regularly.

Our top-performance bits have allowed us to continually do monthly business with the client, and we continue to trial new products in an effort to supply all their drill string needs, e.g. rods and shanks, at Greenbushes as well as other sites the client operates on.
