#0183;#32;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 grinding circuits.
INDUSTRIAL CASE STUDY: THE CEMENT INDUSTRY. operation sites account for over 90% of the California cement industry''s electric. Energy intensity can be examined by combining information on energy. materials are ground into a flowable powder in horizontal ball mills or in vertical roller mills. ball mills in combination with roller presses, roller mills, or roller presses.
