Abstract. Vertical roller mills (VRM) have found applications mostly in cement grinding operations where they were used in raw meal and finish grinding stages and in power plants for coal grinding. The mill combines crushing, grinding, classification and if necessary drying operations in one unit and enables to decrease number of In the case of Slag grinding, the acceptance of roller press in finish grinding is well recognised. It offers the distinct advantage of saving of about 6-7 Kwh/t as compared to Vertical Roller Mill at 4200 Blaine.
