Because raymond mill with stable performance, strong adaptability and high cost performance, it has been widely used in the processing of non-metallic minerals since its introduction in China for more than 20 years. In order to ensure the long-term normal use of Raymond mill, here we introduce some common knowledge of Raymond mill maintenance.

1.During the use of Raymond Mill, there should be fixed personnel responsible for the care, and the operators need to have a certain level of technology. Before the installation of the mill, the operator needs to carry out the necessary technical training to understand the principle performance of the Raymond mill and they should be familiar with the operating procedures.

2.In order to makenormal use of Raymond mill, ” the equipment maintenance operation system” should be established to ensure the long-term operation of the mill, besides, the necessary maintenance tools and grease and corresponding accessories should be also prepared.

3.After using the Raymond mill for a period of time, it should be repaired. At the same time, the wearing parts such as the grinding roller and the blade should be repaired and replaced. The grinding roller device should be carefully checked before and after use to see if there is loosenessphenomenon, whetherthe grease is added.

4.When the grinding roller areused for more than 500 hours to replace the grinding rollers, the rolling bearings in the roller sleeve need to be cleaned, and the damaged parts should be replaced in time. The fueling tool can be manually pumped and greased.

5.Adjust the finenessaccording to the size, hardness, water content and specific gravity of the material, we can adjust the upper analyzer, if the the speed of analyzer is high, the particle is finer, and the output will be reduced accordingly, the fan speed should be debugged if it is not up to the requirement.

6.The scrapping limit of the grinding roller and grinding ringisthe remaining wall thickness shall not be less than 10mm.

7.When the Raymond mill stops, we should stop the feedatfirst, and the main machine continues to smash, so that the residual abrasive continues to be ground. After about one minute, the main machine and the separator can be turned off to stop the grinding work, turn off the fan motor after it purges the remaining powder.
