Despite its prevalence, the efficiency of the conversion of applied force to the creation of new surfaces is extremely poor, none worse than the commonly encountered ball mill. However, tuning of operational parameters may be a means to increase the low efficiency levels, if the proper connection between operating conditions and breakage ...

1. Introduction. Mathematical modeling of tumbling ball mills has evolved tremendously over the last 70 years or so. From the empirical size-reduction relationships (Charles, 1957, Bond, 1952, Morrell, 2004) to the traditional population balance model (Austin et al., 1984, Herbst and Fuerstenau, 1980) and the more recent mechanistic …
