The fitting of the RTD using the cell-based PBM reveals that stirred media mills have much higher R, on the order O(10 0), than the continuous tumbling ball mills O(10 −3 −10 −1). The cushioning action (nonlinear breakage) of the finer particles leads to a coarser product than that predicted by the traditional linear PBM.
