High pressure grinding rolls. A high pressure grinding roll, often referred to as HPGRs or roller press, consists out of two rollers with the same dimensions, which are rotating against each other with the same circumferential speed. The special feeding of bulk material through a hopper leads to a material bed between the two rollers.

High pressure grinding rolls are preferred for their energy efficiency and flexibility in ore processing. 's unique take on this technology, the HRC™ HPGR, delivers even bigger – as the most advanced high pressure grinding roll on the market.
Thus, some of the finish grinding work is handled by the high-pressure grinding roll. The throughput of the existing grinding system can be increased by 50 to 70%, while power consumption can be cut by 20 to 30%. Additional options for high-pressure grinding roll use in gold ore comminution circuits are illustrated in Figure 11.

Comminution, i.e. grinding, is frequently the most energy-intensive step between mine and metal. High pressure grinding rolls (HPGR) are being installed in a rapidly growing number of 'hard rock' mineral processing operations. In the energy conscious cement industry, HPGR grinding has been standard practice for decades.
High pressure grinding rolls are an energy efficient grinding solution, and now has improved this technology even further. The HRC™, our innovative approach to HPGR technology, is like no other HPGR on the market.
With the development of the autogenous wear surface, the high pressure roller press (HPR) is receiving interest from the mineral industry. Previous work by the Coleraine Laboratory had indicated energy saving using a single stage of HPR compared to rod milling and an energy saving using 2 stage HPR compared to single stage HPR.
