• Pressing And Sintering Of Powder Parts

    Pressing force is a function of pressure over the area of the part perpendicular to the direction of pressing. Usually the press is vertical, in this case the horizontal plane of the part would be considered. Force for industrial powder manufacture typically varies between 10,000 lbs/in 2, (70 MPa), and 120,000 lbs/in 2, (800 MPa).

  • 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.
