What are the reasons why the grinding roller of Raymond mill cannot rotate?

1. During the operation of the Raymond mill, the phenomenon of the grinding roller not rotating is mostly caused by the powder grinding entering the roller shaft. Because when the equipment is working, a large amount of powder will be produced in the grinding chamber, and the fine powder will enter the bearing of the grinding roller. After the lubricating oil and dust in the bearing are mixed, it is easy to form oil stains, thereby causing lubricating oil pollution.

2. In this process, the rotation of the inner side of the grinding roller sleeve will be in an abnormal state, and the external contact part with the material will produce greater friction, which has a great impact on the wear of the grinding roller. In this state for a long time, the time of the grinding roller will be shortened, which increases the cost of equipment production and causes a waste of resources.

3. When the roller of the Raymond mill rotates abnormally, it is necessary to stop the machine for inspection immediately, clean the internal dirt, and add new lubricating oil. If the wear is serious, new accessories need to be replaced. In addition, when the equipment is working, attention should be paid to the maintenance of equipment parts to reduce the phenomenon of damage during production, which is of great help to extend the service life of the equipment.

4. For the phenomenon that the roller of the Raymond mill cannot rotate, when the problem is found, the cause should be found out and solved in time. At the same time, the damage can be reduced through daily maintenance to maintain normal operation. Maintenance work needs to be carried out regularly.
