Other designations were also used for the high pressure grinding technology with respect to a wide range of applications from coarse crushing to very fine grinding, such as 'high pressure roller crusher', HPRC. The generic term that has been widely settled upon is HPGR, high pressure grinding rolls, and is used in this paper as well.

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.
