  • HPGR High Pressure Grinding Rolls Weir

    Crushers. HPGR High Pressure Grinding Rolls . HPGR High Pressure Grinding Rolls 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

    Feed material can be smaller than the gap, which is an important distinction as compared to crushers, for example. The high pressure comminution process causes micro-cracks in the particles, which lead to the liberation of minerals and a higher portion of fines. Roll crushers are customized solutions for new or existing crushing plants.
