Modeling breakage rates of coarse particles in ball mills ...

2009-6-1  The first-order rates are commonly observed in batch grinding (Austin et al., 1984) and are the basis of modeling breakage in tumbling mills.In the case of particles contained in coarser size ranges, deviations from linearity are identified in Fig. 1, as have been observed by other investigators (Austin et al., 1982).This behavior, in which grinding rates appear to slow down with time, has ...
