Regarding ball mill design, the full-scale cement mill obviously differs from the laboratory mills in various respects. While the former commonly consists of multiple compartments and multiple diaphragms (Seebach and Schneider, 1987, Ozer et al., 2006, Genc, 2015a), the latter uses a single compartment without partition diaphragms. Thus ...

Peripheral Discharge Ball Mills. The several layers of balls lying on top of those next to the shell follow a similar cycle except that, due to relative difference in the two forces, their paths become more nearly vertical. The outer layers, spreading more than the inner layers, increase the area in the zone of the falling balls.
