Vertical roller mill is the core equipment of modern grinding system. The grinding roller is the vital grinding component of vertical mill. Because the grinding roller can directly exert force on the material the grinding roller has high requirements for hardness and wear resistance in actual production.The CHAENG grinding rollers have the characteristics of high hardness good crack

Roller mills are also more sensitive to instantaneous changes in the feed rate than are other pieces of process equipment. Feeding a roller mill directly from a screw conveyor or bucket elevator will cause surges in the feed rate that the roller mill "sees" instantaneously unless some damping system such as a surge hopper is used.
