Grinding roller and disc liner wear

Vertical mill is a grinding equipment that integrates drying, grinding, powder selection and conveying. It is favored by users because of its small footprint. However, many people have reported that after using the equipment for a period of time, the output is not as good as before, which directly affects the economic benefits. let's look at the factors affecting the vertical mill output and how to prevent the production from falling.

Grinding roller and disc liner wear
When the vertical grinding work, the grinding pressure is applied by the grinding roller, and the material is subjected to the action of pressing and shearing of the grinding roller and the grinding disc to achieve the purpose of grinding the material, so the wear of the grinding roller surface and the grinding disc surface liner is inevitable. As the grinding time is prolonged, the wear of the lining plate will be more serious. The gap between the grinding roller and the grinding disc will become the inner small outer large or uneven shape, the grinding efficiency will be greatly reduced, and the grinding output will be greatly reduced.

In this case, the wear of the lining should be checked regularly. When the grinding roller and the lining plate are worn to a certain extent, they must be replaced in time to avoid the vibration or other problems affecting the vertical grinding operation due to the wear of the lining. The wear of the lining plate should be checked and treated in time. The lining plate can be changed and the height of the retaining ring can be lowered to extend the service life of the lining.
