Tungsten Carbide Hpgr Stud Pin For Cement Crusher Drilling Button
General information about High Pressure Grinding Roller Machines
HPGRs are modern and efficient comminution machines, which are becoming more and more popular in mineral processing.
HPGR technology is a qualified alternative for large-scale comminution circuits and is becoming ever more popular in minerals processing. 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. Feed material can be smaller than the gap, which is an important distinction as compared to crushers, for example.
HPGRs can be employed in brownfield projects to de-bottleneck conventional crushing/milling circuits so as to increase total plant capacity. Furthermore, they can also be used as tertiary and/or quaternary crushing stages or in the pebble-crushing stage to improve downstream milling performance.
