HPGR High Pressure Grinding Rolls
HPGRs first made inroads into diamond processing (where rock fracture along grain lines favored a reduction in diamond breakage during comminution), and in the iron-ore industry. Over the course of the past 20 years. HPGR based circuits have become a circuit commonly evaluated, and there are now many circuits in operation.

High pressure grinding rolls (HPGR) - Outotec
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.
Why HPGRs are revolutionising mill circuits
High Pressure Grinding Rolls consist of two counter rotating, similar sized rolls, which synchronously operate at variable speeds, depending on the plant's requirements, which force particles to crush one another and compress the feed's density to 80% of its solid volume.
