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.

To understand the performance of a vertical roller coal mill, the real operational tests have been performed considering three different coal sources. Obtained results indicate that grinding pressure, primary air (PA) temperature and mill motor current have a tendency to rise by increasing coal feeding mass flow rates for all used coal.
