A total scale-up method for planetary mill is discussed in this section. All parameters ( d M, h and R) of the basic planetary mill were scaled-up as t p times to investigate the effect of the scale-up ratio on E i. The scale-up ratio was changed from 0.50 to 3.00 ( V M = 170 – 36 650 cm 3; n B = 80 –17 496).

Austin et al. [23] favored the integration of the batch grinding solution with an appropriate residence time distribution to predict the mill product size distribution. This approach has already been successfully used to describe continuous ball mills operating at both pilot and industrial scale using a mechanistic model [28].
