VRM shown in Figure-1 uses hydraulically hard-pressed conical shape 2-4 rollers against the horizontal revolving grinding table. To enhance comminution, the axes of table and rollers do not traverse in the plane of the table and approximately 150 inclination angles between
MoreAbstract. 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 ...
