The fineness of raw materials used to be controlled at the level of several percents of 90 micron residue in the old wet process or others. As the burning method changed to SP and NSP, efforts were made to reduce the power consumption rate at the raw material process by increasing coarseness.

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 equipment in …

re VRM vs Ball Mill for Cement Grinding. Specific power consumption- high for ball mill and Low for VRM. Maintenance costs- high for VRM and low for Ball mill.
