A time dynamic model of a high pressure grinding …

Traditional models of high pressure grinding rolls (HPGR) crushers rely heavily on survey data to make accurate predictions. In this paper, a consolidation of previous approaches of modeling comminution machines is combined with insights from crusher modeling to develop a time dynamic process model of the HPGR. The crusher is modeled from a mechanistic point of view.

High pressure grinding rolls (HPGR)

High pressure grinding rolls (HPGR) are used for size reduction or rocks and ores. They compress the feed material between two rotating rollers, one of which is in a fixed position and another roller that is floating. The two rotating rollers generate such a high pressure that it grinds the feed material to the desired smaller grain size.
