Vertical roller mill is widely used in cement raw material, fuel and cement grinding system, and is equipped with feeding and discharging system. However, the feeding and discharging system often has an unsatisfactory effect. For this reason, we analyze and deal with the common problems of the system and solve the problems. 01 Process flow
The material falls through the screw feeder's discharge port and falls in the center of the grinding table. When grinding the roller table area, it is crushed by the grinding roller, and the bulk material is crushed directly, and the fine-grained material is extruded to form a material bed for inter-particle crushing.
