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 compressive strength with equal pressureHigh Pressure Grinding Rolls - 911 Metallurgist,28/07/2020· High Pressure Grinding Roll Features & Performance.
