High Pressure Grinding Rolls HPGR

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.
