1. Introduction. Grinding is an essential procedure used in almost every mineral processing operation to reduce particle size, and to liberate or expose the valuable minerals (Fuerstenau and Han, 2003).The size reduction of solids is an energy intensive and inherently inefficient process; less than 1% of energy consumed in comminution is used for actual size reduction (Rhodes, 2008).
