Comminution specialist thyssenkrupp has rewritten the crushing and grinding technology rule book with the introduction of the High Pressure Grinding Rolls (HPGR) Pro.

Based on over three decades of proven grinding technology, our development of the HPGR Pro has taken a market-leading product to the next level of performance and reliability,” comments Gerhard van Wyk, who heads up Technical Sales at thyssenkrupp Industrial Solutions.

Used as a grinding unit upstream of ball mills, this machine incorporates smart design engineering and a host of innovations for enhanced mineral processing plant operational and production efficiencies. The cost-efficient HPGR Pro can boost throughput significantly at lower-specific energy input. Rotating side plates and a skew limiting device improve the grinding efficiency of the machine.

Visitors to the thyssenkrupp Industrial Solutions stand in Hall 6 will be able to view a three-dimensional print of the HPGR Pro, as well as some of the company’s other innovations, including the eccentric roll crusher (ERC), a ball milll, combiflex gearbox for mills and cone and jaw crushers.

A team of specialists will also be on stand-by to offer information on thyssenkrupp Industrial Solutions’ in-pit crushing systems (IPCC) and crawler mounted spreaders.

The ERC is designed, developed and manufactured by thyssenkrupp to deliver highly efficient, cost-effective crushing capabilities for bulk and precious metals.

“Equipped with state-of-the-art features, the energy efficient ERC offers a new dimension in technology for hard rock primary crushing, delivering a large throughput,” states thyssenkrupp Industrial Solutions crushing and screening technologies product manager Demitri Kokoroyanis.

The ERC is suited for underground and surface mines, mobile and semi-mobile crushing plants in openpit mining, mineral processing plants and quarries. The compact, low profile machine boasts a small footprint and low maintenance.

Integrated screening, automated hydraulic control system, an automated gap adjustment and a retraction system ensure smoother downstream processing and automated operation. The symmetrical arrangement of the roll allows the crusher to be balanced with great precision which significantly reduces machine vibrations and loads on surrounding structures.

thyssenkrupp Industrial Solutions business development manager for materials handling Henry Swart draws attention to the versatility of its heavy-duty conveying systems, typically found in opencast mines.

“Owing to our successful integration of the unique functionality of these conveyors with crushers, excavators and or spreaders, we have created innovative mining systems over the past 40 years.”

These tailings, waste and/or discard systems are operated autonomously and are typically found in the power industry and mines where continuous operator involvement is kept to an absolute minimum and production load losses cannot be tolerated.

“We have close on 100% market share in South Africa when it comes to these heavy-duty ramp, extendable and shiftable conveyor installations combined with rail or crawler mounted spreaders,” affirms Henry.

According to Demitri, dependant on the current and future mining plans, IPCCs are very much in demand, especially for high volume capacities. “There are currently more than 285 plants installed globally in different mining commodities. IPCCs deliver reduced energy costs by eliminating time from the blasting area to tipping to crush the run-of-mine for transporting material. This technology continues to develop, adding further value through reduced emissions, lower maintenance and improved safety. Additionally, we continue to incorporate our latest crushing technology into these plants with some of the largest gyratory crushers and now our latest ERC machine.”

thyssenkrupp Industrial Solutions CEO for Middle East and Africa Wilfred Barkuizen says: “We support our product portfolio with excellent after-sales service delivered by highly skilled technicians as well as through our state-of-the-art-equipped service centre. The thyssenkrupp team is prepared, ready and eager to share product and technology knowledge and expertise in crushing and grinding, materials handling, mining and revamp with customers during Electra Mining.”
