  • 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 pressure being applied to particles of all

    High Pressure Grinding Rolls (HPGR) consist of two rolls of identical dimension, that rotate against each other at the same circumferential speed. The main grinding action is a result of interparticle crushing. Extreme pressure causes the particles inside the compacted material bed to fracture into fi ner particles and also causes microfracturing at the grain size level. • Model RPM: HPGR
