The grinding process of the vertical mill is completed by a set of grinding device (i.e. the mill roller and the mill disc), and the material is ground into powder between the mill roller and the mill disc. The mill roller of the vertical mill roller type vertical mill is a core component, and the quality of the mill roller affects the processing effect of the equipment.
