Working Principle of Vertical Mill

Read Time:49 Second



It will fall freely under the action of gravity, and the abrasive body will be crushed like the projectile. The cyclic movement of the rising and falling of the grinding body is recurrent. In addition, in the process of vertical roller mill, the grinding body also produces sliding and rolling, so the grinding body, the lining plate and the material will be lapping, so that the material is fine.

Due to the continuous feeding of new materials at the feed end, there is a material difference between the feed and the discharge end material, which can force the flow of material. And when the grinding body falls, the impact of the material produces axial thrust, which also forces the material to flow.

In addition, the movement of air in the mill also helps the material flow. Therefore, although the barrel of the mill is horizontally placed, the material can flow slowly from the feed end to the discharge end and finish the grinding operation.
