Predicting the effect of operating and design variables in grinding .
WEBJul 1, 2021 · 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].
