In the ultrafine mill machine, there are two lubrication methods: rare lubrication and grease lubrication. The thin oil lubrication inside the reducer below the ultrafine mill can remove the dust impurities and heat inside the bearing through the thin oil, protect the bearing from dust pollution, and protect the bearing from excessive heat damage. The separator on the upper part of the ultrafine mill is greased. The grease lubrication can reduce the friction between the bearings and reduce the chance of bearing damage.

Wear parts are a major expense for ultrafine mills and are essential for making powder products. The material is ground in the gap between the grinding disc and the grinding sleeve, causing the wear of the two kinds of wear parts. If not replaced in time, the parts under the grinding roller and the grinding disc will also be worn, which will lead to a sharp increase in operating costs. Therefore, it is necessary to replace the wear parts in time. In addition, the distance between the grinding roller and the grinding disc should be adjusted in time with the wear of the wear parts to ensure the normal operation.
