Do You Know the Application of Superfine Mill?

Superfine mill is also called superfine grinding mill, which is a kind of Raymond mill, and which is widely used in grinding and processing processes of mineral materials in metallurgy, building material, chemical, mining and other fields. There are various kinds of inflammable and explosive mineral materials that can be ground by this mill, such as quartz, feldspar, clay, talc, calcite, clay, barite, fluorite, gypsum and clay whose humidity is below 6%.

1. The superfine mill should be used with the bin and electromagnetic vibrating feeder. The grinding roller and motor are directly related to the uniform feeding situation of superfine mill. Feeding too much will cause the overloading processing of motor for a long time. Uneven feeding can cause stress on roller, inner bearing and oil seal. If the stress frequency is not regular, it will reduce the service life of bearing and oil seal.

2. The regulation of the fineness for the superfine mill is the combination of flow and the rotational speed of the classifier. A reasonable allocation of air volume and speed can achieve high yield and good fineness effect. During the production of coarse powder, classifier can be stopped and the fan door opened. If necessary, the classifier wheel can be removed to reduce the pressure loss of fan. During the production of fine powder, the classifier motor is needed to be opened, if necessary, the motor classifier can be equipped with a frequency converter, which can carry out step less regulation of the speed. When producing fine powder, it is better to increase the volume of the blower as large as possible. The high rotating speed of classifier is the assurance for the high yield of fine powder.

3. The wind closing device at the lower part of the cyclone separator should be checked to ensure the close state of super cyclone separator. Keep the cyclone separator close to avoid air internal circulation, low yield and large power consumption. The above skills of superfine...
