An important aspect in the performance of the high pressure grinding rolls (HPGR) is its throughput. The HPGR throughput can be changed by varying the speed of the rolls, but, it is important to determine the effects of changes in the rolls speed together with other variations such as grinding force and feed size, on the overall performance of the HPGR.
