Maintenance key points in the use of superfine grinder

Ultra-fine grinders are generally used in industries, machinery and other industries. Due to long-term gravitational labor, the service life of the ultra-fine grinders is affected to a certain extent. Even if there is improper operation or feeding problems during use, it is very It is easy to affect the use of the pulverizer. Here, we will introduce the maintenance key points of the superfine pulverizer in two sections, and hope to help you when using the pulverizer.

1. The grinder 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 feeder of the crusher;   

3. Regularly check the fineness of crushed products;   

4. Regularly clean or replace the dust collector bag (to ensure that the bag is ventilated), and regularly check the working condition of the solenoid valve (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 hammer of the crusher 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 two opposite (1800 direction) hammer pins The total weight difference of the hammers on the shaft ≤ 2g;   

8. When the grinder screen is severely worn and needs to be replaced, pay attention to the flatness of the new screen and whether the size of the screen is reasonable, whether the installation is in place, it is recommended to make the screen wool face inward during installation;   

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

10. If abnormal conditions such as large vibration and high noise of the crusher are found, the machine should be shut down immediately for inspection;  

11. The main shaft bearing should be added 80 grams of grease after every 40 hours of operation, 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 changing to 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 case. Do not add too much grease;  

12. When it is found that the output of the ultra-fine grinder suddenly drops, in addition to the factors of raw materials, check whether the air supply door is in place, whether the pipeline is leaking, whether the pulse cloth bag is blocked, whether the solenoid valve, the fan are working normally, etc.
