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.
