Regarding ball mill design, the fullscale 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.
