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.
Used in mining appli ions 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.
