High Pressure Grinding Roll ("HPGR") technology is very rapidly gaining a wide acceptance within the mineral processing industry. Benefits from energy efficiency and a low overall operating cost

The high pressure grinding roll machine comprises a pair of counter-rotating rolls mounted in a sturdy frame. One roll is fixed in the frame, while the other is allowed to float on rails and is positioned using pneumo-hydraulic springs. The feed is introduced to the gap between the rolls and is crushed by the mechanism of interparticle breakage.
