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.
The MPS mill also grinds, dries, calcines, and classifies gypsum without any problem, all in a single machine, for any fineness requested and considering individual requirements. The MPS vertical roller mill - built to last, reliable and energy-efficient - is the optimum solution when it comes to performing several process steps in one unit.
Vertical roller mills and ball mills represent two clearly distinct technologies. However, with proper adjustments to the operational parameters of the vertical roller mill almost identical cement properties can be achieved by the two mills that satisfy the cement user's demands.Nevertheless, the two types of mills have their distinctive merits.

Vertical Mills. Vertical mills (such as bowl, roller grinding, ball-and-ring, and roller mills) are mainly used for comminuting limestone, clinker, slag, lime, gypsum and ores for the building industry and raw material processing. They reduce raw material from a thickness of 30 mm to a very fine-grained material.
