1.The manufacturing precision of grinding ring

 Since the grinding ring rotating with the spindle is one of the main wearing parts when the grinding mill is working, the manufacturing precision of the grinding ring directly affects the service life of the grinding ring, and the key points are to control the radial runout of the grinding ring and the heat treatment deformation of the grinding ring, radial runout and internal diameter deformation will increase the impact on the grinding roller, vibration, and increase the additional load, thus shortening the service life of the grinding roller and the grinding ring.

2.The positive pressure of grinding roller and the gap between grinding roller and grinding rings

The positive pressure of the grinding roller is adjusted by an external spring. The appropriate spring pressure must be adjusted according to the hardness, particle size, moisture content, feed size and fineness of the desired product, while the grinding roller and the grinding ring are used. The gap between them is an important parameter that directly affects the yield and fine powder content. Generally speaking, the material processed by the user is relatively fixed. At this time, the gap between the grinding roller and the grinding ring should be adjusted according to the size of the feed particle size. If the gap is too large or too small, the yield and fineness will be affected, and also increase the vibration of grinding mill. In addition, after the grinding mill has been working for a certain period of time, due to the wear of the grinding roller and the grinding ring, the gap between them will gradually increase, and the adjustment should be made in time.

3.The lubrication of the main machine and classifier

The main machine and classifier of grinding mill are lubricated with oil. The main shaft of the main machine and the three grinding roller components are externally provided with a lubricating oil tank, and all the bearings are immersed in the lubricating oil for reliable lubrication and cooling. The user can observe the level of the oil level on the fuel tank and fill the oil as required.
