During the production process of the Raymond mill, someone should be present to oversee it, and this person should have some technical knowledge. The operator of the grinding machine needs to receive professional technical training and understand the detailed operations. Be able to understand the principle of the grinding mill and be familiar with the procedures for each step. 2. To ensure the proper operation of the Raymond mill, a strict maintenance regime must be followed to enable long-term use; in addition, a complete set of lubricants and common disassembly tools should be available. 3. After the Raymond mill has been in operation for half a year, a thorough inspection is required; replace those grinding rollers, grinding rings, and shovels that are severely worn out, and check whether the connection bolts and nuts of the grinding roller assembly have become loose before and after use. 4. The service life of the grinding roller unit is 500 hours, after which it can be replaced with a new one. The moving bearings inside the roller sleeve need to be replaced; those that are damaged can be discarded. Grease can be injected using a grease gun, which is cost-effective and helps improve lubrication, thereby reducing wear. This type of grinding machine often experiences various faults during operation; the causes of these faults are analyzed as follows: Fault analysis of Raymond grinding machines. I. Faults in the power distribution system – Unstable power supply to the motor is a problem that cannot be ignored; in severe cases, it can even cause the machine to burn out. Electrical protection devices should be installed. II. Stirrer unit failures: (1) Motor rotation direction issues, broken stirrer blades, and the discharge outlet getting stuck on other objects. (2) The feeding is too fast, and the conveyor belt lacks strength. III. Grinder faults (1) The machine is unstable and shakes back and forth; tighten the nuts connecting the grinding head to the frame. (2). Unable to meet the production volume: tighten the springs, check the distance between the two ends of the grinding roller, and inspect the grinding teeth. (3) The discharged material is too hot, causing wear and requiring replacement of the grinding rollers ； Stop the machine and let it rest for a while. IV. Screen failure: If the screen is shaking, the bolts should be tightened. Counterattack crusher
