Chapter 5 Comminution Engineering360

Introduction. Comminution in the mineral processing plant, or mill, takes place as a sequence of crushing and grinding processes. Crushing reduces the particle size of run-of-mine ore to such a level that grinding can be carried out until the mineral and gangue are substantially produced as separate particles.

Computation of bubbly cavitating flow in shock wave

Abstract. However, the particulars of the comminution mechanism (s) are still undetermined. In this work, a numerical model of the two-phase flow inside an electrohydraulic lithotripter was used to provide additional insight in the behavior of the bubble cloud. The numerical model is based on an ensemble averaged two-phase flow model
