In cement production, tube mills having multichambers are traditionally used either in open or closed circuit operations. After the introduction of high compression grinding mills (High pressure grinding rolls (HPGR), vertical roller mill (VRM) and Horomill), various circuit configurations have been developed for energy efficient grinding.

The application of vertical roller mills (VRMs) for ore grinding is a part of the strategies against rising energy consumption (Reichert et al., 2015). The VRM technology was introduced in the mid'90s for grinding clinker and slag by LOESCHE (Schaefer, 2001). Fig. 1 illustrates the grinding parts of a Loesche vertical roller mill.

Vertical roller mill maintenance can be broken down into three general areas; rolls, bearings, and drives. In order to achieve best roll life and consistent performance from end to end the rolls must be parallel and tram. If rolls are allowed to operate out of parallel, not only is the product inconsistent (fine on one end, coarse on the other ...
