Daily maintenance method of Raymond mill

 

For Raymond mill, daily maintenance and care is a very important task. Raymond mill is mainly composed of: main machine, analyzer, fan, finished product cyclone separator, micro powder cyclone separator and air duct. Among them, the main machine is composed of: frame, air inlet volute, scraper, grinding roller, grinding ring, cover and other accessories.

After understanding the composition of Raymond mill, let’s learn about the daily maintenance method of Raymond mill:

  1. During the grinding process of Raymond mill, there should be fixed personnel to supervise and be responsible. The operator must have a certain technical level. Secondly, the operator must receive necessary technical training so that he can understand the principle and performance of Raymond mill very well and be familiar with the operating procedures before the operator can control the Raymond mill.
  2. After the Raymond mill has been used for a period of time, it should be inspected and repaired when it is shut down. At the same time, the grinding rollers, grinding rings, scrapers and other vulnerable parts of the Raymond mill should be inspected and replaced. The connecting bolts and nuts of the grinding roller device should be carefully checked before and after use to see if there is any looseness and whether the lubricating grease is sufficient. If not, please solve it immediately.
  3. When the use time of the grinding roller device of the Raymond mill exceeds about 500 hours, the grinding roller should be replaced, the rolling bearings in the roller sleeve must be cleaned, and the damaged parts should be replaced in time. The refueling tool can be refueled with a manual refueling pump and butter.
  4. In order to ensure the normal grinding operation and toner requirements of the Raymond mill, the scrap limit of the grinding roller and grinding ring of the Raymond mill is that the minimum wall thickness of the remaining grinding roller and grinding ring shall not be less than 10mm. Once the wall thickness of the grinding roller and grinding ring is found to be less than 10mm during the inspection, the grinding roller and grinding ring must be replaced immediately to avoid affecting the milling effect.
  5. When the Raymond mill needs to be stopped, the feeder should be stopped first, but the main machine should not be stopped and should continue to work so that the residual abrasive can continue to be ground until all the materials in the mill are discharged. Then the main machine motor and analyzer motor can be turned off to stop the grinding work, and then the fan motor can be stopped to blow away the residual powder.
