    Raw Material Vertical Roller Mill. 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.Working Process of Vertical Roller Mill. Grinding process materials are: motor through reducer drive disc rotates, the material falls under the spout from the central disc, mobile and by rolling the roller to the edge of the disc under the effect of centrifugal force, leaving the material crushed disc, is to speed up the flow and vertical mill with integrated splitter, splitter after meal after returning to the disc, re-grinding
