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.

In addition to ball mills, one of the other common mills in factories is the vertical roller mills (VRMs). In contrast to grinding by ball mills that need other devices to dry and separate powder, VRM performs separation, grinding, and drying processes just in one machine and reduce the number of devices in a close circuit.
