    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 particles of all …
