HRC™ Series high pressure grinding rolls (HPGR) - Metso ...

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.

HPGR High Pressure Grinding Rolls | Weir

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 ...
