Raymond Mill is a new type of mill that replaces ball mills to process powder. Its various technical indicators have reached the domestic advanced level, and it is highly praised by users in various industries. So for Raymond mill, daily maintenance and maintenance is a very important task.

Structure of Raymond Mill
Raymond mill is mainly composed of: main engine, analyzer, fan, finished product cyclone separator, micro powder cyclone separator and air duct. Among them, the main engine is composed of: frame, air inlet volute, blade, grinding roller, grinding ring, cover and other accessories.
Compared with ball mills, Raymond mills have advantages such as higher efficiency, lower power consumption, smaller footprint, and one-time investment. When the Raymond mill is working, the grinding roller is tightly crushed on the grinding ring under the action of centrifugal force, so the degree of wear of the grinding roller and grinding ring is relatively large. When the wear exceeds a certain thickness, the It will directly affect the output and fineness of finished products.

Raymond mill maintenance method
1. During the milling process of the Raymond mill, there should be fixed personnel in charge. The operator must have a certain technical level. Secondly, the operator must have the necessary technical training so that he can understand the Raymond mill very well. The principle and performance, after being familiar with the operating procedures, 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 roller, grinding ring, blade and other wearing parts of the Raymond mill are repaired and replaced. The grinding roller device is in use The connecting bolts and nuts should be carefully checked before and after to see if there is any looseness and whether the lubricating grease has been added enough. If not, please solve it immediately.
3. When the grinding roller device of the Raymond mill has been used for more than 500 hours, the grinding roller should be replaced again. The rolling bearings in the roller sleeve must be cleaned, and the damaged parts should be replaced in time. The oiling tool can be used Use a manual oil pump and a grease gun for refueling.
4. In order to ensure the normal grinding operation and toner requirements of the Raymond mill, the scrapping limit of the grinding roller and ring of the Raymond mill is the minimum wall thickness of the remaining 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 test, the grinding roller and grinding ring must be replaced immediately to avoid affecting the milling effect.
5. When it is necessary to stop using the Raymond mill, the feeding machine should be stopped first, and the main machine cannot be stopped, but continue to work, so that the residual abrasive can continue to be milled until all the materials in the mill are discharged. , you can turn off the motor of the host machine and the motor of the analyzer, stop the milling work, and then stop the motor of the fan to blow off the residual powder.
During the use of Raymond mill, various problems will occur, so it is very important to take precautions in advance, which not only reduces the loss of the enterprise, but also prolongs the service life of Raymond mill, killing two birds with one stone.
