The Design Principle of Vertical Roller Mill

11.07.2016· Vertical roller mill, is vertical mill for short, is a grinding processing equipment dealing with raw material such as cement, cement clinker, slag and cinder. Vertical roller mill has features of a simple structure, low manufacturing cost. Experts of Shanghai Clirik studied the impact of curvature of the disc, roller to grinding capacity and unit power consumption, toDesign Advantages of Vertical Roller Mill,01.10.2019· Reasonable design of rocker, grinding roller and millstone. The vertical roller mill adopts the bed materials grinding working principle. The grinding roller and grinding roller bushing are hanging on the up through rocker. When there is material on the millstone, the material will enter into the grinding roller and millstone. Under the movement of millstone, materials will be grinded. This design will prevent the collision of grindingVertical Roller Mill,Verical Roller Mill Types,The design idea of vertical roller mill. Grinding principle of vertical roller mill is the use of 2 ~ 4 rollers to the disc, as the speed of rotation the ground material, basically belongs to the material layer grinding. The material is mainly due to the rolling action of grinding roller and grinding in the mill, the grinding roller and disc rotation speed difference between, so has the shear milling.
