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.

Material is directly conveyed to the silos (silos are the large storage tanks of cement) from the grinding mills. Further, it is packed to about 2040 kg bags. Only a small percent of cement is packed in the bags only for those customers whom need is very small. The remaining cement is shipped in bulk quantities by mean of trucks, rails or ships.
