    SummaryOverviewOperationPrincipleMethod of operationBenefits over ball millLimitations

    Vertical roller mill is a kind of grinding machine for cement, raw material, cement clinker, slagand coal slag. It has the features of simple structure and low cost of manufacture and use. Vertical roller mill has many different forms, but it works basically the same. All of these forms of machine come with a roller (or the equivalent of roller grinding parts), and roller along the track of the disc at the level of circular movement imposed by external grinding roller in the vertical pressure on the disc on the material being the joint act

  • Vertical Roller Mill Structure And Working Principle

    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.

  • Comparison Grinding Principle of Ball Mill and Vertical

    Ball mills and vertical roller mill use different forces to achieve the necessary size reduction of clinker and gypsum plus other materials.. In ball milling, the size of the material is progressively reduced through the impact and attrition forces on the feed material as the rotation of the mill causes the tumbling action of the grinding media.
