In main unit’s working process, grinding roller device not only performs gyration by surrounding the central axis，but also performs revolution by surrounding the grinding ring. The grinding roller itself self- rotates by rubbing effect, the merit of which is that it can not only fully pulverize material, but also ensure uniform wear around grinding roller, increasing service life of grinding roller. perching knife, which is installed under grinding roller hanger, rotates with grinding roller at the same time. In this process, the perching knife throws up materials and feed them into grinding ring of grinding roller to form a padding layer. This padding layer is pulverized through outward centrifugal force generated by grinding roller（namely extrusion force between grinding roller and grinding ring）for the purpose of pulverization.
