  • 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
