HPGR High Pressure Grinding Rolls WeirHigh Pressure Grinding Rolls HPGR TENOVA

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 The technology s working principle is that two counter rotating grinding rolls expose a column of material to high pressure which is distributed across the gap between the rolls Interparticle comminution is the HPGR specific grinding process in which material particles are crushed and ground within the compressed material bed and not by contact with the roll surface
