During the wear process of the grinding roller, the materials that pass through the grinding zone continuously and contact the surface of the grinding roller directly may produce alternating contact stress. It leads to a very small amount of contact fatigue on the surface of the grinding roller, and the phenomenon of pitting or falling off occurs.
