Ultrafine pulverizers are generally used in industry, machinery and other industries. Due to long-term gravity labor, the service life of ultrafine pulverizers is affected to a certain extent. Even if there is improper operation or feeding problems during use, it is very likely to cause problems. It is easy to affect the use of the pulverizer. Here, we introduce the key points of maintenance in the use of ultra-fine pulverizer in two sections. We hope it will be helpful to you when using the pulverizer.

1. The crusher motor has been lead-sealed before leaving the factory, and the coupling has been calibrated, please do not loosen it; 

2. Regularly clean the iron impurities on the permanent magnet cylinder and the permanent magnet plate of the crusher feeder; 

3. Regularly check the fineness of the crushed products; 

4. Clean or replace the dust collector bag regularly (make sure the bag is breathable), and check the working condition of the solenoid valve regularly (to see if it can work normally); 

5. Regularly check the wear of the wearing parts of the crusher to see if it is normal wear; 

6. Always pay attention to the vibration of the crusher;

7. When the pulverizer hammer is seriously worn and needs to be replaced, pay attention to weighing to ensure that the weight difference between the two opposite hammer pins on the two opposite (1800 direction) hammer pins is ≤1g and the weight difference between the two opposite (1800 direction) hammer pins The total weight difference of the hammers on the shaft is ≤2g; 

8. When the screen of the crusher is seriously worn and needs to be replaced, pay attention to the flatness of the new screen, whether the size of the screen is reasonable, and whether the installation is in place. It is recommended that the rough surface of the screen faces in during installation; 

9. The opening degree of the air supply door of the impeller feeder should be adjusted appropriately;  

10. If abnormal conditions such as large vibration and high noise are found in the crusher, it should be stopped immediately for inspection; 

11. After every 40 hours of operation, 80 grams of grease should be added to the spindle bearing, but it can only be added to 60%. After 1800 hours of operation, the bearing box cover should be removed and all used grease should be replaced. When replacing with fresh grease, add grease to the area around the rollers and bearing rings, and add 1/3 to 1/2 of the grease to the bottom box. Do not add too much grease; 

12. When it is found that the output of the ultra-fine grinder suddenly drops, in addition to raw material factors, you should focus on checking whether the air supply door is in place, whether the pipeline is leaking, whether the pulse bag is blocked, and whether the solenoid valve and fan are working properly.
