Working Principle And Structure
The grinding roller moves along the horizontal circular track on the grinding disc, and the vertical pressure of the external roller applied on the grinding roller causes the material on the millstone to be combined with the extrusion and shearing and can be crushed.
The main factors affecting the grinding efficiency of a vertical roller mill include its screw diameter, screw pitch, rotational speed and medium layer level.
Vertical Roller Mill In Cement Industry
The selection rate of vertical mill in the raw materials, coal, cement and slag grinding accounts for 85%, 80%, 70% and 93% respectively. Vertical roller mill has become the preferred grinding equipment in the cement industry. Environmental protection advantages are obvious, and achieved good economic results, and has good prospects for development.
