How to solve the tightness of ore ultrafine mill?

The ultra-fine mill is a kind of mechanical equipment commonly used in ore grinding. The ultra-fine mill can be used for grinding of limestone, dolomite, calcite and other ores. It is indispensable for industries such as industry, metallurgy and chemical industry. Key mechanical equipment. As a professional manufacturer of ore processing machinery and equipment, Shanghai Clirik Mining Machinery is here to talk to you about the sealing problem of the ultra-fine mill.

 

Grinding rollers and grinding rings are very important components in the ultrafine mill. The material is sent to the main body of the mill through the feeder, and then squeezed into the powder by the grinding roller and the grinding ring in the grinding chamber. Everyone should pay attention to that the grinding roller of the ultrafine mill is easy to be damaged due to high temperature and impact, which leads to poor sealing, which causes impurities such as dust to enter the interior of the ultrafine mill and damage the machine parts.
 

The grinding roller bearing gland of the superfine mill is generally composed of three seals: upper, middle and lower seals. The upper oil seal is used to seal the oil, the lower oil seal is used to prevent dust, and the middle oil seal is the felt seal. Soaked, so as to ensure that the grinding roller does not leak butter in the oil seal, the wool felt still plays a lubricating role, and will not burn out.
