Optimise your pebble crushing with HPGR

With the cone crusher handling the initial coarse reduction, preventing wear on the HPGR's tyres and allowing a more economical HPGR size to be selected. The HPGR complements the operational life of the cone crusher liners, whilst generating a finer product that frees up the circuit's milling capacity.

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....
