Comminution theory focusses on the relationship between energy input and the particle size produced from a given feed size. 2 The most common breakage methods are impact and attrition, mostly by ball mills. This compares with the compression mechanism, as well as attrition, utilised in both highpressure grinding rolls (HPGRs) and vertical roller mills (VRMs).
