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.

Heat taken away by ventilation systems can accounts for roughly 20% of the total heat discharged by the ball mill. Improving that ventilation system brings more cool air into the inside of the ball bill, gradually reducing the internal temperature. However, the major benefit of using ball mills is the product fineness they can deliver.
