Atlas Copco

Atlas Copco’s new ultra fuel-efficient drill rig, the SmartROC CL, was unveiled for the first time in public at MINExpo, ahead of its official world launch this month.

For the thousands of open pit miners around the world who use Down-The-Hole (DTH) drilling technology, the new rig will certainly be seen as a major step forward. Not only have the designers managed to slash fuel consumption by 45 percent, averaging 35 l/h using a 165-mm drill bit, they have also boosted the achievable penetration rate by 50 percent compared with conventional DTH rigs currently in use.

The engine power required to drive various functions and operations can now be controlled and optimized in a way that was previously not possible, thereby minimizing the amount of diesel fuel consumed overall.

The design of the COPROD drill string which, combined with a choice of robust, high-powered rock drills up to 50 KW, gives the kind of high penetration rates normally only achieved in top hammer drilling together with the superior hole quality that comes with DTH drilling.

In addition, this package includes a range of automated, time-saving features including automatic rod handling, hole navigation system and the ability to operate the rig by remote control using Atlas Copco’s BenchREMOTE system. Coupled with Surface Manager, Atlas Copco’s drill-management software, this rig will be unbeatable in mining applications.

Mattias Hjerpe, product manager, said: “Many of our customers in, for example, Australia, South Africa, Latin America and Scandinavia, who use the DTH drilling method, now have a great opportunity to slash their fuel bills and boost their productivity at the same time. It’s a winning combination.”

McLanahan Corp.’s Rotary Scrubbers are ideal for helping producers remove water-soluble clays, deleterious materials and coatings from a variety of hard rock and ores, but can be over 100-ft. long, 40-ft. wide and 25-ft. high and weigh more than 838 tons empty. To give mining producers the opportunity to see this equipment up-close-and-personal, McLanahan turned to the Gear Virtual reality (VR) system, powered by Oculus Technology.

Booth attendees received a complete experience with the rotary scrubber, as well as the jaw crusher. Visitors wearing the headset walked around and inside both these pieces of equipment for an experience like no other.

“It’s pretty incredible to look back over the four years since the last MINExpo and see changes that have happened both at McLanahan Corp. and in the mining industry,” said Sean McLanahan. “The changes in the commodities markets, which you all know have been tough, have caused us to look closely at how we serve our customers around the world – from the products we offer to the need for local service and support in emerging markets.

“In 2015 alone, we opened three new global offices, restructured internally to improve our focus on products, took our solutions into new industries, and delivered innovative new products to the market. Through it all, our main goal has been to make sure we are giving our customers the service and support they need – whether that means serving them from local offices or asking them what they need to improve their operations,” McLanahan said.



Philippi-Hagenbuch showcased its Material Spreader body. The Material Spreader was designed primarily for mining but with benefits in a variety of applications, including construction, aggregates, quarries and landfills. It provides a safe and efficient solution for mine haul road maintenance as well as improves the safety and traction of icy haul roads in winter by applying road grit. During spring thaw, the material spreader easily tackles deteriorating road areas by spreading repair material and building up areas.

“We receive multiple requests every year for a sanding body that can apply grit to haul roads,” said Josh Swank, Philippi-Hagenbuch vice president of sales. “When we started designing the material spreading system, we wanted to ensure that it met the same criteria as all of our products. This spreader, like all PHIL products, is robustly built to withstand the harshest worksite conditions, simple to operate, and designed to maximize efficiency and achieve the truck’s true hauling capacity.”

The heart of the system is a patented PHIL rear-eject body coupled with the new material spreader attachment. The Material Spreader easily spreads road grit, sand or other material ranging in size from very fine to more than 2 in. Operators can easily adjust the material spreading width from about 15 ft. to more than 60 ft. The haul truck operator controls the material spreading rate and width from the truck’s cab.

An optional top-loading Grizzly Screen controls the maximum size of the material being spread. The ejector blade on the proven PHIL Rear-Eject Body moves material to the rear of the body and into a Cross Auger Channel. The auger gathers material to the center of the spreader and then discharges it onto a set of Material Spinners for spreading.



Sandvik showed its Panterea DPi series drill rigs, which it said provide improved technical solutions for boosted productivity Sandvik has engineered notable productivity upgrades into the well-known DPi series surface top-hammer drill rigs. The latest release of the Pantera DPi series drill rigs introduces such features as a redesigned operating system combined with other substantial upgrades and a completely new rock drill.

The Pantera DPi drill rigs include a redesigned control system with an updated user interface and touch screen.

To optimize drilling performance Pantera DP1500i is now available with a high frequency RD1635CF rock drill with Circulating Shank Lubrication (CSL) system that guarantees fast and efficient penetration. In CSL oil is circulated through filters and reused, rather than just collected. “The new CSL system reduces shank lubrication oil consumption by up to 70 percent compared to the old system, and significantly increases coupling sleeve life,” said Jarno Viitaniemi, product manager, surface boom drills, Sandvik Mining and Rock Technology. “The drill rig has really been redesigned with economy in mind. It has also been enhanced with a new compressor control system that provides even better fuel efficiency.”

Further Pantera DPi improvements include modifications to the exterior design, which improves accessibility thereby enabling easier maintenance. In addition, the drill rig comes with the latest high-tech options, such as Driller’s Notes. The latter is a completely new feature that allows the operator to add hole information, such as voids and cavities, to hole-quality reports during drilling.


Superior Industries

Superior Industries Inc. showed its new Patriot Cone Crusher at MINExpo. The high-performance cone is the manufacturer’s first entry into crushing technologies for bulk processing applications. 

Besides a strong commitment to service and convenient access to wear parts, the Patriot Cone Crusher will be recognized for rugged structural integrity and high-grade components to extend service life. Internally, bronze sleeve bearings are used for all moving components that are load bearing or perform load transmission (including countershaft bushings, thrust bearings, head and eccentric bushings and socket liners). In addition, these critical components are cast of high-grade steel, which typically exceeds standards for conventional cone crushers.

Superior said engineers uniquely designed high throw and high-pivot point crushing performance to achieve strong production rates at a low cost per ton. Mobile applications will appreciate a readily mounted design for transportation on a cone/screen chassis.

For protection from costly structural damage, each Patriot Cone Crusher is equipped with fail-safe hydraulics to defend the unit against damaging mechanical overload. Additionally, standard relief valves within the dual acting tramp release cylinders provide immediate, alternative protection should the accumulator fail. Engineers also developed overload sensing technology. In the event of force overload, a simple alarm can activate or optional advanced sensing technology will automatically take the necessary corrective action. This same automation can control the feed rate to optimize performance, adjust other settings and monitor critical lubrication and hydraulic parameters.



Terramac, a manufacturer of innovative rubber track crawler carriers, offered various models that deliver superior performance and versatility to tackle the toughest mining jobs. Terramac’s RT9, RT14 and RT14R crawler carriers are well-appointed to provide operators with maximum efficiency and easy maintenance, the company said.

The greatest feature that sets Terramac’s units apart from other vehicles is its rubber track technology. Terramac crawler carriers exert minimal ground pressure while fully loaded, making them ideal for loose and wet ground conditions where heavy, wheeled or steel track machines are likely to get stuck. Flotation from the units’ rubber tracks leave a minimal footprint and less disturbance on the soil while providing reduced slippage to conquer adverse conditions, climb faster on rugged terrain and reach remote areas.

The robust Terramac products feature powerful Cummins diesel engines and added torque, allowing operators to tackle a wide-range of mining applications with ease. Terramac crawler carriers also boast large carrying capacities to ensure quick cycle times and keep productivity levels on point – regardless of application.



Volvo debuted the A60H articulated hauler. The machine offers a 60-ton payload capacity. This new-to-industry hauler class opens increased production opportunities and cost savings potential not previously possible with smaller articulated haulers or rigid trucks in the 60-ton size class, Volvo said.

“The A60H is a perfect fit for contractors who typically run multiple articulated haulers on long-term earthmoving projects. In many cases, customers could expect reduced operating costs by replacing two smaller trucks with one A60H,” said Eric Fatyol, product manager, GPE products at Volvo Construction Equipment. “The A60H could also open up new areas of production for mine and aggregate sites by providing access to areas of the site that were previously inaccessible with rigid trucks. Similarly, the A60H could extend the production season in harsh-weather regions and also eliminate the need for hiring outside contractors to handle overburden work.”

Powered by a 673-hp Volvo D16J engine and built upon the Volvo platform, the A60H goes where others can’t, noted Volvo. The active hydraulic front suspension, hydro-mechanical steering and high ground clearance at the articulation joint enable the A60H to easily and comfortably navigate severe terrain, and the rotating hitch design makes the articulation joint virtually maintenance-free. Automatic traction control (ATC) and 100-percent differential locks continue to be a competitive advantage for Volvo.

The no-slip, no-wear differential locks work in 4×6 and 6×6 drive combinations. This industry-unique design employs the front two axles in full-time, and the back axle kicks in as necessary – allowing unmatched off-road performance while reducing fuel consumption and tire wear. With oil-cooled, wet, multiple disc brakes on all three axles, stopping distance is impressively short – even on steep, muddy gradients.
