High pressure grinding rolls (HPGR) are used for size reduction or rocks and ores. They compress the feed material between two rotating rollers, one of which is in a fixed position and another roller that is floating. The two rotating rollers generate such a high pressure that it grinds the feed material to the desired smaller grain size.

High pressure grinding rolls (HPGRs) have seen an increased global popularity over the past decade, due to the development of more powerful variable-speed drive (VSD) systems. ABB's VSD solution plays an integral role in providing high-throughput and energy efficient grinding – making HPGRs a competitive alternative to SAG mills.

Pressure is then applied to one of the rolls (floating) by means of a hydropneumatic spring system while the other is fixed in the frame. The feed is introduced by a hopper mounted above the rolls, between which it is compressed under high pressure giving rise to breakage amongst the individual particles.

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.
