Raw Material Vertical Roller Mill

Vertical Roller Mill Working Principle. In a vertical roller mill, materials to be ground fall upon the center of a rotating grinding table. Centrifugal force causes the materials to spread out evenly towards the edge of the plate. As particles lying flatly on the plate reach a certain thickness, they are ground or crushed by multiple pairs of rollers. When the crushed particles fall off the
