HPGR technology is a qualified alternative for large-scale comminution circuits and is becoming increasingly popular. 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

In-feed grinding is also a form of centerless grinding. This process, however, is optimized for workpieces with complex or abnormal shapes. The workpieces must be manually loaded into the grinding machine and then the regulator wheel is manually moved, as well. This process is optimal for complicated parts and wheel shapes.

Smooth or profiled rolls can tolerate larger sizes – however at the expense of wear. For optimum grinding effect, the rolls should be choke-fed. Underfeeding the rolls re-duces breakage and causes excessive wear at the center of the rolls. Misconception 4. "It is more efficient to grind truncated feed than full feed size distributions".
