High Pressure Grinding Rolls (HPGR)The technology's working principle is that two counterrotating 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.
arsenic high pressure grinding rollsHigh pressure grinding rolls. A high pressure grinding roll, often referred to as HPGRs or roller press, consists out of two rollers with the same dimensions, which are rotating against each other with the same circumferential speed. The special feeding of bulk material through a hopper leads to a material bed between the two rollers.
