    Grinding Pressure In Vertical Roller Mills.the materials fall down the center of grinding table from feed opening. At the same time, hot air comes into the mill from the air inlet. due to the centrifugal force, materials move to the edge of the grinding table. the materials are pulverized by the roller when by pass of the groove on the grinding table.

    The working principle of vertical roller mill: ... During the pulverization process, the material is subjected to the pressure of the grinding plate and the shearing force generated by the movement between the grinding plate and the grinding roller. After the material is extruded, a bed is formed on the track of the grinding machine, and mutual ...

    2019-11-6 · Cement grinding process: The grinding process in ball mills and vertical roller mill s differ fundamentally. In a ball mill the comminution takes place by impact and attrition. The comminution in the vertical roller mill takes place by exposing a bed of material to a pressure sufficiently high to cause fracture of the individual particles in ...
