Inline kiln/raw mill means a system in a portland cement production process where a dry kiln system is integrated with the raw mill so that all or a portion of the kiln exhaust gases are used to perform the drying operation of the raw mill, with no auxiliary heat source used. In this system the kiln is capable of operating without the raw mill operating, but the raw mill cannot operate ...

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.
