These roll crushers have large forces of compression and are called high pressure grinding rolls (HPGR). The present trend is to replace secondary cone crushers by HPGR. The work at Polysius [3] and described by Friedrich and Baum [4] , and Otte [5] indicates considerable metallurgical advantage in the extraction of minerals such as gold and copper by the use of high pressure grinding rolls.

Used in mining applications for the last 30 years, high pressure grinding rolls (HPGR) reduce particles by compressing and crushing the feed between two counter rotating, parallel rollers with a small gap between them. This forces the rocks against each other and compresses the feed’s density to 80% of its solid volume, exceeding its compressive strength with equal pressure being applied to

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.

Unfortunately, high pressure grinding rolls continue to be confused with conventional roll crushers. HPGR comminution is substantially different from impact, attrition and abrasion comminution as it occurs in crushers, SAG and ball mills. The HPGR comminution occurs in a bed of particles between two counter-rotating rolls where only a limited amount of the ore is in contact with the rolls. The
