The metal tungsten forms the basis for valuable high-tech components in many industries. With its mine in Mittersill, Wolfram Bergbau und HĂĽtten AG, Mittersill/Austria, operates one of the most important tungsten mining operations worldwide. As the ore is being selectively extracted at ever greater depths and the uphill transport routes are becoming ever longer, a new Sandvik processing plant was built and recently commissioned in a specially constructed underground cavern (Figure 1).
The Wolfram company is a strategically important part of the global Sandvik Group and the only integrated tungsten smelting plant outside of Asia and Russia. As a result, the company has expertise in all aspects of the process, from exploration through to the finished product. Scheelite is extracted in the state-of-the-art underground mine in Mittersill and is used as a primary raw material at the smelting plant in St. Martin im Sulmtal, together with tungsten concentrates purchased from around the world.
The recycling of secondary raw materials containing tungsten at the recycling centers in Chiplun (India) and St. Martin plays an important role in conserving natural resources and completely closing the supply chain loop. Used indexable inserts or drill bits, e. g., are processed back into tungsten powder.
The target for 2030 is a recycling rate of 80 %. In the interests of sustainability, investments are continuously made at each site in the optimization of the recycling process, the further development of the circular supply chain and the complete conversion to sustainable energies.
Mining and processing in Mittersill are where Wolfram’s production line begins. Here, 65 employees are involved in mining and another 25 employees in processing. The raw ore is transported into the processing plant in an environmentally friendly manner by means of a conveyor belt through a tunnel. The raw ore is used to produce the scheelite concentrate, which covers a significant portion of Wolfram’s raw material requirements, thus ensuring independence and security of supply.
The deposit’s varying ore grades are defined by means of exploratory drilling. A wide variety of mining methods are used for the selective extraction of the scheelite. The resulting cavities are completely refilled. The drilling work is carried out with face drill rigs, bouldering rigs and longhole drill rigs (down-the-hole hammer and top hammer).
The mining points are connected by a winding main ramp, the lowest part of which is 550 m above sea level. This is 800Â m below the main opening and already well below the existing old crushing and processing plant. As the uphill transport route to the crushing plant continues to grow longer as the mining progresses, the construction of a completely new processing plant in the current mining area was discussed for the first time in 2020. After comparing various operating and production factors, which also included the use of electric dump trucks, it was decided that a new processing plant should be constructed around 300 m below the existing plant. An intensive planning phase followed in 2021, during which the Plant Manager Stefan Eggenreich and his team worked together with Project Manager Alois Raffelsberger from Sandvik SRP to develop a solution. After completion of the planning, the contract for the entire machinery and steel construction was awarded to Sandvik Rock Processing CEU in 2021. Before the first assembly work could be started, the cavern for the new processing plant had to be excavated. In close coordination with all parties involved and the responsible authorities, 3D planning of the cavern was precisely carried out with the aid of state-of-the-art measurement technology.
At the end of 2022, the first steel components and machines were delivered, which were gradually moved into the underground cavern. Assembly of the steel structure was started by the company Trost in Matrei in Osttirol/Austria. The innovative, medium-sized steel and mechanical engineering company specializes in large-scale projects in all application areas and its project management team made a valuable contribution to the project during the construction phase of the plant. In the next step, all the processing units, such as the crushing and screening technology, belt conveyors, reciprocating feeders and dosing troughs, were assembled and installed by Sandvik technicians. The assembly work was completed at the end of 2023. Cold and hot commissioning took place in 2024, and the system has been operational since 22nd March 2024 (Figure 2).

One focal point in the design phase was the construction of the heavy-duty preliminary stockpile with the hydraulically lockable needle gate specially developed for this job, through which blast rubble up to 1,200 mm in size is transported away via the lintel shaft.
Both at the needle gate and before the jaw crusher, a Sandvik 999E rammer hammer was installed in order to quickly and safely eliminate potential jams. Below the preliminary stockpile is a Sandvik SH2071M reciprocating plate feeder, which transports the material by means of a hydraulic moving-floor conveyance system via a SV2131 vibrating feeder to an in-line CJ815 jaw crusher. The single-toggle jaw crusher has an inlet of 1,500Â x 1,100 mm and reduces the maximum grain size to 250 mm. Below the jaw crusher is a silo, which has been blasted out inside the mountain and from which the material is transported to a linear vibrating screen via a Sandvik SP1630 pan feeder. Here, the material is separated at 60 mm. Material of 0 to 60 mm in size is deposited in an ore stockpile. Two dosing troughs below the ore stockpile and Sandvik belt conveyors transport the material to a steep conveyor system from which the material is conveyed to the surface installation. Material larger than 60Â mm is fed in a closed circuit to a CS840i cone crusher, a premium cone crusher from the Sandvik 800i series. A stockpile is used upstream of this as a buffer to achieve the desired uniformity. Secondary crushing in the CS840i produces a grain size of 0 to 60 mm. The material is screened again via the return belt until the desired degree of particle reduction is reached. The process and layout design, as well as the detailed engineering of the plant, was carried out by the Sandvik Rock Processing team in close cooperation with the client.
Although the construction of the new processing plant represents a major investment, it is much more economical compared to the future operating costs of an unchanged transport concept. Wolfram Bergbau und HĂĽtten AG is thus taking an important step toward future-proof optimization of further mining operations.
Thanks to its wide range of models, Sandvik is, among other things, the market leader in surface drilling rigs, which can be seen as key for extraction in quarries and open pit mines. Sandvik has repeatedly demonstrated through groundbreaking developments that a high-performance overall drilling system is more than just the sum of its components. When all components are perfectly matched to each other, impressive increases in results can be achieved, as Sandvik now proves with its latest product innovation. The first striking feature of the new CT drill system is its innovative curved thread design, but the Sandvik CT is much more. It represents a really effective newly developed system for top-hammer drilling, which brings about a real quantum leap in drilling efficiency through a wide range of optimized details, as a wide variety of application scenarios show after just a few months.
Many large companies have been working with Sandvik for decades. These include, e. g., the MHI Group, which operates one of the most important hard rock quarries in Germany in Nieder-Ofleiden, amongst other places. Many people are probably familiar with the location, as the SteinExpo takes place here every three years. The company has been relying on Sandvik’s drilling technology for more than 20 years, they currently have a Pantera DP1100i working in the quarry. With a purchase in 2018, it is in its “prime” age and has proven itself over many thousands of meters of drilling in difficult conditions, to the complete satisfaction of MHI. There was a lot of excitement when Sandvik announced in 2023 that it wanted to make a functioning overall package even better, as operations manager Philipp Tuschhoff admits.

“Of course, as a supplier, you have to bring good arguments to convince an important customer like MHI to convert the drilling rig for test operation,” explains Ekkehard Bolle, Sales Manager for the Drilling Tools division. After all, the Sandvik Pantera is not only used for drilling in Nieder-Ofleiden, there are also three other locations being drilled with this machine. Initially some conversions were necessary when the new CT55 and CT67 system became available. At MHI, the Sandvik Pantera DP1100i was equipped with a predecessor thread system (ST58). For the conversion, Ekkehard Bolle advised MHI to convert to the larger diameter of the CT67 (Figure 1). In order to do this, the Pantera had to be equipped with new clamping jaws, magazine plates and a larger flushing head. The reason for this can be found in the thread design: The energy of the hydraulic drifter is no longer transferred via the bottom of the thread, as is the case with the ST58 tool system, but via the so-called shoulder at the male end of the thread. As a result, the shank has become wider and requires a larger flushing head. “We trusted Sandvik’s expertise and were not disappointed,” says Tuschhoff happily afterwards.
Test operation has started since mid-July 2023. In Nieder-Ofleiden, a classic columnar basalt with all its (drilling) problems can be found: a great density and strength, irregularly fissured, especially between the basalt columns, plus with embedded softer tuff zones. Drilling through those soft layers and repenetrating the compact basalt zones, the bending stiffness of the drill string is of immense importance and the drill holes do not deviate. Internal stresses in the drill string are kept at a minimum when, as in Nieder-Ofleiden, the drillholes are drilled up to 30 m into the basalt. This has a great effect when the drill string is extracted and the 4.3 m rods can be uncoupled easily. Comprehensive success was not lacking: As of early November, MHI decided to take over the new CT67 thread system on a permanent basis and has drilled a total of more than 15,000 m with it. “The effects were indeed enormous and immediate,” recalls Tuschhoff, adding: “The most obvious effect was actually the enormous increase in performance and a fuel saving of 30 % as a direct result.” This could only be explained to a small extent by the larger flushing head, which of course allowed for a higher capacity. Rather, the “inner values” of the tool provide an explanation. Because the design increased the stiffness by 45 % compared to GT60 rods, Sandvik was able to implement an enlarged flushing channel for the CT67 rods. As a direct result, the total weight of the drill string is almost unchanged compared to the well-known GT65 – another remarkable detail. The increased bending stiffness allows higher percussion and feed pressures to be achieved with high drilling accuracy at the same time. “As an indirect consequence, we were able to select 96 mm Sandvik semi ballistic drill bits that last longer while at the same time improving penetration speed,” says Tuschhoff, pleased with one of the additional synergy effects. Sandvik product specialist Ekkehard Bolle is also aware of the importance that the curved shaped thread system has in terms of overall performance: “The special geometry associated with the thread design reduces the specific loads by distributing the impact energy over a larger area within the thread, the result is lower tensions in the string.” MHI, in turn, notices its effects in daily use, because both rattling when changing rods and coupling are made much easier. “These are only a few seconds, but in total this makes a considerable acceleration and the automation of the drilling process could also be efficiently improved as a result,” confirms Tuschhoff.
The fact that the successful optimisations at MHI are no coincidence can be seen at the same time just 50 km further west: Basalt AG (BAG) operates a quarry on Paleozoic diabas at the Stockhausen site. Here, Chief Operations Manager Bernd Eiding has been relying on drilling rigs from Sandvik for many years as well. Since June last year, a Sandvik Pantera DP1500i has been newly commissioned and has been equipped with the CT67 system directly on the recommendation of local Sandvik dealer Ralf Ogroske (Figure 2). It was not necessary to convert subcomponents, especially the flushing head, as the predecessor GT65 tool was already installed here. In diabase, the driller has to reckon with rock sections of varying hardness, and clayey insertions repeatedly make easy drilling difficult. “The differently hard sections and irregular fractures are already a challenge here and we also drill into the weathered overburdens when expanding the benches,” describes Eiding. He was really surprised by the obvious increase in efficiency: “Because the CT67 system can be operated at higher pressures, we have since achieved penetration rates of 1.2 to 1.3 m/min – as opposed to 0.9 with the old tool system.”
By reducing the annular space and the associated increase in the flushing speed, precise drilling with increased percussion power is possible. When pulling the string, it is noticeably easier to uncouple the rods, which results in lower tensile stress on all components involved, from the entire drill string to the hydraulic drifter. One question that was of particular interest to Eiding and the BAG in this context was the quality of the holes, especially the hole deviation according to the specified planning. “We have some of the holes checked immediately after drilling, if only to make sure that the necessary specifications are met, because nobody wants flyrock here”. The result was very convincing. The drilled holes, which are up to 26 m deep, were measured by blasting engineer Joachim Milde with the probe and were extremely accurate, even with a driller who was not very experienced in these operating conditions.
As with MHI, the Sandvik Pantera at BAG is also underutilized with the one location and so the operator supplies other BAG quarries from the Stockhausen site if necessary. “Even after the first experiences here at the site, we believed that the CT67 system could do all rock conditions, whether greywacke, basalt, quartzite or quartz keratophyr,” says Eiding enthusiastically and: “We were not disappointed.” After no less than 15,000 m of drilling performance with an improved service life compared to the GT65, BAG was convinced to convert another Sandvik Pantera rig to the CT67 drill system.
The experience gained in a wide range of practical operations impressively proves the thesis that even the perfect machine can only ever be as good as the tools with which the actual work has to be done. “The previous Sandvik GT concept has proven itself with our customers over the past 20 years and has ensured extremely reliable and productive drilling,” explains Sandvik man Bolle, adding: “The task was familiar from previous years, but we were able to confidently approach the most demanding customers with the new CT tool, because we had already had the rod system very successfully tested at Kautz drilling company in Dortmund since May 2022 and proven in use.” Furthermore, in 2023, the possible applications of the CT67 from granite to limestone were extensively tested with a Pantera DP1100i demonstration machine all over Germany. These demonstrations ultimately led to the successful sale of the complete Sandvik Pantera and CT67 system to two customers. The successful interplay of good service by the local dealer Ralf Ogroske and Sandvik’s Ekkehard Bolle to adjust the machines exactly according to the requirements of the company and a good price-performance ratio of the tools is demonstrated several times.
Featuring an industry-first curved thread design, Sandvik’s new CT55 and CT67 top hammer tool systems are the most advanced the company has launched. The unique design increases efficiency and reduces cost while saving fuel and simplifying automated drilling in surface bench and underground longhole applications.
The new multi-patented, first-of-its-kind curved thread design from Sandvik reduces stress levels by distributing them over a larger area inside the tool. This enables the system to handle higher drilling power and a drill rig’s full potential.
“We are proud to offer an innovation that delivers significantly increased efficiency, since higher drilling parameters are allowed with fewer stops for breakages,” said Anders Brungs, Vice President Product Line Top Hammer at Sandvik. “Our design increases productivity by 15 percent while reducing fuel consumption by 15 percent, as faster drilling means less flushing time.”
Sandvik’s unique new curved thread CT system is designed to increase drilling productivity and reduce cost both underground and on the surface.
“Surface drill rigs have much more power than current standard tools can handle,” said Fredrik Björk, Product Manager for Top Hammer Surface Tools at Sandvik. “This means the full potential of the drill rig cannot be used. Our new CT system radically increases the fatigue strength and we’ve also seen 30 percent longer tool life together with better hole precision in our product evaluation tests with early-adopting customers. This is a fully optimized system that includes the drill rig, the rock drill and the rock tool. The CT system also brings out the full potential of Ranger™ DXi and Pantera™ DPi rigs.”
The higher productivity of the CT systems can be reached with more aggressive settings for parameters like percussion, rotations and feed.
“Trouble-free drilling is key when operating underground,” said Robert Grandin, Product Manager for Top Hammer Underground Tools at Sandvik. “In addition to higher productivity and lower cost, the extended service life of our CT system will be especially important for underground operations where tool breakages create frustration and interrruptions. The stronger geometry that comes with the curved thread design boosts tool service life by more than 30 percent. The curved design also makes the CT system automation-ready, since easy coupling and uncoupling in itself is an important enabler for automation, a vital technology in many underground operations.”
Sandvik’s new curved thread systems, CT55 and CT67 for surface mining and CT67 for underground mining, are now available. Drill bit diameters are 89 – 127 mm on CT55 and 102-140 m on CT67, plus reaming bits 152-204 mm.
Sandvik Mining and Construction Central Europe GmbH rates steinexpo as one of the most important trade fairs this year. A variety of exhibits will be on display in specially defined areas of the 1,250 m² Sandvik stand highlighting the manufacturer’s competence in its core market of the raw and construction materials industry. Product innovations and significant new developments from the Sandvik portfolio in the segments of drilling technology, mobile and stationary rock processing as well as from the area of wear protection and screening media demonstrate the strength, performance and practical understanding of the manufacturer. In addition, digital features in the program address current user expectations in the Industry 4.0 age.
Acting globally and expanding the locally recognized market presence with confidence is one of the challenges that large companies like Sandvik have to master. In addition to its own organizations, such as the Essen-based Sandvik Mining and Construction Central Europe GmbH, reliable and well-known partners are essential for regional success. Consequently, Sandvik is also planning this year’s demo fair participation together with its dealers TTS Trump Technik and Ferronordic. Both dealers represent Sandvik Mobile crushing and screening in Germany, and will be available to answer visitors’ questions specifically about mobile equipment.
Crushing technology for mobile and stationary applications
Designed specifically for applications in the rock industry: The remarkable CH800i cone crusher series, which includes this CH840i, addresses users with high quality awareness. Photo: Sandvik
Spotlight of the stationary crushing technology is the CH840i cone crusher – from the CH800i series – a technologically advanced, high-performance medium-sized unit for secondary and tertiary crushing in processing plants of mines or large quarries.
Hydrocone crushers of this series have a hydraulically supported main shaft, which is supported at both ends. Thanks to the robust construction, an adjustable stroke and the CLP Sandvik OEM crushing chamber design, high production capacity can be achieved with consistent product quality.
The CH840i comes with the latest generation Automation & Connectivity System (ACS) as standard. The system continuously monitors and optimizes crusher utilization and controls the complete lubrication system to increase machine availability and reliability. ACS also automatically adjusts crusher settings in real-time to match variations in feed curve and material hardness. This compensates for wear in the crushing chamber to ensure consistent product particle size.
Bolted instead of welded wear protection elements on the upper and lower housing reduce maintenance times by up to 90%. All service and inspection work is carried out from above. This makes the relevant work safer and also reduces the maintenance effort required for the robustly designed crusher series.
Other features that protect against wear or delay its progress include the improved overpressure system with special air inlets. It protects against dust and increases reliability. A standard offline filter unit keeps the lube oil cleaner through fine filtration, reducing wear on internal crusher components and extending oil life by up to five times.
Weighing just under 25.8 t, the CH840i cone crusher achieves throughputs of between 212 and 659 t/h, depending on crushing chamber, feed material and desired particle size. The maximum feed size is specified at 431 mm. A variety of standard crushing chambers are available for each model in the range. The Hydrocone can be easily adapted to production-side changes by selecting the appropriate crushing chamber and stroke.
The exhibition will be complemented by the first joint product presentation in the area of screening technology. Through the acquisition of the screening technology manufacturers Kwatani (formerly Joest Afrika) and Schenck Process Mining, the portfolio in the area of screening technology has been substantionally expanded over the past two years. In addition to a DF classifier exciter and linear vibrating screens, a wide variety of screening media will be presented, as well as a web-based monitoring system for monitoring screening machines.
Mobile plant operators will find the QJ341 on display, the largest mobile jaw crusher in Sandvik’s world-leading Q series, with its own fuel-efficient  stage V CAT diesel engine, hydraulic drive and overband magnet. Designed for use in quarries and demanding recycling applications, the continuously improved mobile plant, which weighs almost 49 t, is ideally equipped for tough operating conditions. The single-toggle jaw crusher is certified to have a capacity of up to 400 tph. Built for durability, it comes complete with many features as standard such as a level sensor, central lubrication, dust suppression system, extended main conveyor with a raise and lower facility for removal of blockages.  A radio remote control for the tracks makes it easy to move the machine on site. Integrated into the My-Fleet telematics for mobile crushers and screens, the system supplies important data via an online portal, to optimize machine performance.
 The latest generation(s) of digital support for preparation.
With the new “SAM by Sandvik” tool, a digital assistant is now available to provide insight, support and information needed to increase productivity in stationary crushing and screening. A constantly evolving digital service, SAM was launched to optimize operations. Activities and data flow together in a user-friendly, seamless collaboration tool. Technical managers, operators and service technicians get a complete view of what’s happening across the plant, maintenance managers are informed about the condition of all equipment, and buyers can get to the SAM web store without any obstacles.
As the new best friend of plant managers, SAM offers its services in “SAM Standard” and “SAM Connected” variants. While the Standard variant includes the benefits already described (and a few more), the “Connected version” offers an additional utility plus, for example, by making it possible to track parameters of Sandvik cone crushers equipped with the ACS-c, ASRi 1.x or 2.x automation system in the SAM web application or via mobile devices using SAM apps (available in the Apple Store and Google Play).
Following the acquisition by Sandvik, the CONiQ cloud system formerly developed by Schenck Process is being consistently further developed and integrated into the existing digital infrastructure and product world. This solution acts like a virtual bridge between screening equipment and relevant digital services. In this case, too, the recorded operator data is the key to digital services such as remote service or efficient spare parts management. Thanks to the stored empirical values from machine and process tests, it is possible to predict with high precision how the machines will react under almost all operating conditions.
The service includes a data-driven model that predicts normal behavior based on historical data and current machine and process operation. Unlike normal condition monitoring based on predetermined absolute alarm limits, the approach focuses on the difference between measured and predicted value; the so-called residual value. This reflects the degree of deviation from normal operation and is more sensitive to changes of any kind. The goal is not only safer and more efficient operation, but also an extended response time for operators so that they can take appropriate action before a possible machine failure. For vibrating screens and vibrators, the monitoring system includes numerous wireless and three-dimensional fully synchronized motion sensors distributed at critical positions around the machine. Based on this sensor data, a 3D wireframe video representation of the machine motion can be generated. Via a slow-motion function and the amplification of non-ideal motion patterns, even non-experts can detect unfavorable deviations.
The information provided is converted into an easy-to-understand graphical representation of threshold values in trend diagrams. In addition, a machine learning-based anomaly detector highlights deviations from normal signal patterns. When an anomaly is detected, the system sends a warning email with compressed relevant information to the defined responsible parties.
The system is always supported and supplemented by ad-hoc service experts for current and historical machine problems. Thanks to a high degree of flexibility, the digital tool, designed as a plug & play solution, can be adapted to any type of process equipment, integrated into existing systems and updated as required.
Equipment for the first step in the process: the rock excavation

On display, there will also be a machine that will make its debut in Germany, the Commando™ DC300Ri-based electric concept drill rig. The new concept rig is a versatile research and development platform to demonstrate some of the most advanced technologies to be introduced in future surface drill rigs. The event is an excellent opportunity for visitors to discuss the visionary electric concept drill rig with Sandvik’s surface drilling product experts.
Even the most perfect machine can only ever be as good as the tools with which the actual work has to be done. With the introduction of the innovative, patented Curved Thread systems CT55 and CT67, Sandvik Rock Tools promises to improve the utilization of the machine and thus increase productivity enormously. Combined with our powerful DXi and DPi series drill rigs, the CT system supports higher penetration rates while maintaining low hole deviation.

The curvature profile and design of the thread reduces stresses at critical – and therefore crucial – points, which are common with standard systems, and every corner of the product is optimized for fatigue strength, allowing more efficient energy transfer. In addition to the positive effect of optimized energy transfer, which results in higher productivity with lower fuel costs thanks to a faster penetration rate per meter, the curved thread also makes the coupling and uncoupling process much easier. Long tool life and fewer premature breakages geniting lower total drilling costs, round off the multitude of positive effects with this new system. The CT55 and CT67 thread system will be one of the highlights at steinexpo Sandvik booth.
Sandvik Mining and Rock Solutions is introducing Toro™ LH518iB with AutoMine® (Figure 1). The automation-ready battery-electric underground loader is undergoing extensive factory testing, with the first unit scheduled for customer delivery during the first half of 2023 and AutoMine® compatibility available in the second half.
Toro™ LH518iB marries industry-leading battery-electric and automation technologies. Building on predecessor Sandvik LH518B, he features several design updates and significantly improved field serviceability. The latest version of Sandvik’s intelligent control system enables AutoMine® readiness. Sandvik’s patented self-swapping battery system, including the AutoSwap and AutoConnect functions, benefits from improvements to the operator’s controls to facilitate battery swaps.
Toro™ LH518iB is automation ready and the loader can be equipped with Sandvik’s AutoMine® system. The 18 t loader is equipped with standard valves, harnesses and other built-in hardware for automation. The AutoMine® onboard kit will be available as an option, providing scanners, AutoMine® box and wireless connectivity.
With AutoMine®, one operator can run the entire cycle from a surface chair, including tele-remote battery swapping. Human involvement underground is only required for connecting and disconnecting batteries from chargers and coolers.
“We are extremely proud of this new loader that will set the standard for productive, sustainable and autonomous underground mining,” said Jari Söderlund, Head of Product Management, Division Load and Haul, Sandvik Mining and Rock Solutions. “This is not experimental technology that will be ready sometime in the future. It is developed and ready to be delivered to our customers this year.”
Factory tests of the new loader are ongoing. The first Toro™ LH518iB units are being prepared for customer deliveries in North America, Australia, Europe and Southeast Asia. Deliveries are planned to start during the first half of 2023. Sandvik will closely monitor performance and production metrics in conjunction with the customers.
Rana Gruber has selected Sandvik Mining and Rock Solutions to supply a fleet of 19 battery-electric vehicles (BEVs), including trucks, loaders and drills, for its iron ore operations in Storforshei in northern Norway (Figure 3). The agreement underpins Rana Gruber’s aim to operate the world’s first carbon-free iron ore mine by the end of 2025.
Sandvik’s second-largest battery-electric mining fleet to date will include six Sandvik TH550B trucks, five Sandvik LH518B loaders, four Sandvik DL422iE longhole drills, two Sandvik DS412iE mechanical bolters and two Sandvik DD422iE jumbos. Delivery of the equipment has begun during first quarter of 2023 and is planned to continue through 2024. Sandvik will also provide on-site service support and batteries.
“We’re proud that our mining operations already have among the industry’s lowest CO2 footprints but we have even higher ambitions to completely eliminate our carbon emissions,” said Gunnar Moe, Chief Executive Officer of Rana Gruber. “We have a crystal-clear decarbonization strategy. When we announced our 2025 goal in 2020, many did not believe it would be possible, but we’re taking another major step forward partnering with Sandvik to implement a battery-electric fleet that will improve our work environment and reduce our operational costs. Most importantly, BEVs will help us achieve our ambitious goals for carbon-free mining.”
Moe said Sandvik’s philosophy around batteries and approach to battery safety was an important factor in Rana Gruber’s selection process.
Established in 1964, Rana Gruber produces approximately 1.8 Mt/a of iron ore concentrates from its five deposits in Norway’s Dunderland Valley. Its resource base includes more than 440 Mt of iron ore.
Sandvik has supplied underground equipment to Rana Gruber for more than 25 years. The companies signed a cooperation agreement to strengthen their partnership in November 2021. Trans4Mine, Sandvik’s in-house consultancy, conducted studies and simulations to advise Rana Gruber on BEV fleet requirements, charging station locations and other mining cycle optimizations, resulting in a letter of intent in November 2022.
“BEVs have demonstrated their power to reduce a mining operation’s carbon footprint,” said Mats Eriksson, President of Sandvik Mining and Rock Solutions. “Rana Gruber is a pioneer in the mining electrification shift in Europe, and we look forward to supporting their battery-electric transition.”
Sandvik Mining and Rock Solutions has launched a highly-automated, compact, twin-boom drill for underground development and small-scale tunneling. Sandvik DD322i (Figure 1) is a versatile drill that can be utilized in mining or tunneling applications and provides a high level of performance, accuracy and reliability. It has a new carrier and design, and can tram in small headings, tight corners and intersections thanks to its compact size, low profile cabin and Boom Control While Tramming option.
“Sandvik DD322i was very successful and well-received by our customer during the field testing in Finland earlier this year,” said Jari Talasniemi, Product Manager for Development Drills. “The site reported that almost 60 % of their development drilling during the trial period was completed using Sandvik DD322i. It performed extremely well from day one and the Boom Control While Tramming feature was useful for their operation.”
The Boom Control While Tramming option allows the operator to simultaneously control the two booms while tramming, ensuring improved control when moving the drill and reducing potential risk of boom damage. The new SB55i booms with two roll-overs ensure improved drilling performance and accuracy, as well as high flexibility to drill crosscut and bolt holes. Sandvik DD322i can also be equipped with features such as semi-automatic drill bit changer and tele-remote drilling to make underground operations safer and more productive.
Sandvik DD322i provides flexibility for operations, starting from small size drifts up to 58 m2 coverage area, reaching up to 6.8 m high and 9.5 m wide. The new SB55i booms provide 19.3 m2 side coverage, which is over 48 % more than its predecessor, Sandvik DD321.
The low profile cabin has been redesigned and the new larger glass doors offer 55 % more visibility, maximizing safety and improving operator comfort while creating a modern, spacious and ergonomic working environment. Larger displays provide an improved user interface and Sandvik DD322i is compatible with Sandvik’s digital offering, including Sandvik DrillConnect, iSURE®, AutoÂMine®, OptiMine® and My Sandvik.
Scalable automation packages and tele-remote drilling are available as options for Sandvik DD322i, enabling better drill utilization and continuous working hours over shift changes and during blasting and ventilation hours.
