Aug 20, 2020. Closed circuit cement mill. The strength development of concrete is the result of the chemical reaction of water with cement particles. The reaction always starts at the surface of the cement particles. Thus larger the surface available for reaction, greater is the rate of hydration and strength development.

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.
