• 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. Feed material can be ...

    High Pressure Roller Press Grinding In Cement Plant. Normally, when the material is continuously fed to the two grinding rolls and goes through them, a certain force is given to the movable roller, thus the material is held by the two rotating rollers and moves downward with the rolls. at this time, in a certain area between the grinding rollers, the material particles will form a material layer.
