When higher rolling resistance is applied due to particle shape complexity at less mill speed, more vertical force is exerted on the roller, and the roller speed is insensitive to rolling resistance. This study provides the basis for further experimental investigations on industrial-scale VRM and supports the design optimization of the VRM.

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 mills grinding an OPC of low fineness, say around 3000 cm2/g (Blaine) can operate without grinding aid, but even when grinding to that low fineness, grinding aid improves the output rate as well as the specific energy consumption. Recent experience has shown that water has an effect similar to that of a grinding aid.
