Modeling of grinding mill and circuit is and continues to be a challenging theme for many researchers. Grinding models are mainly used in grinding circuit simulators for process optimization [1], design of control strategies [2,3] and for the analysis of the effect of a change of operating conditions (ball size, shape, rotation speed etc.) on the mill efficiency [4,5].

This is consistent with the relatively low collision energies of the grinding media in this mill (Fig. 2). Indeed, these deviations from firstorder breakage rates have been observed by the authors for ball mills grinding coarse particles [32, 34], being this identified as 'abnormal breakage region' by Austin and coworkers [51].
