While operating the foam pulverizer in strict accordance with the operating procedures, keep in mind the following tasks:
1. The motor of the pulverizer has been 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 pulverizer feeder;
3. Regularly check the fineness of the crushed finished product;
4. Regularly clean or replace the bag of the dust collector (to ensure that the bag is breathable), 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 pulverizer to see if it is normal wear;
6. Always pay attention to the vibration of the crusher;
7. When the hammer blades of the pulverizer are severely worn and need to be replaced, attention should be paid to weighing to ensure that the weight difference between the two opposing hammer blades on the shaft of the two opposing (1800°) hammer pins is ≤ 1g and that the weight difference between the two opposing (1800°) hammer pins The total weight difference of the hammer on the shaft is ≤2g;
8. When the screen of the pulverizer 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, and it is best to make the wool of the screen face inward during installation;
9. The opening degree of the supplementary air door of the impeller feeder should be adjusted properly;
10. If abnormal conditions such as large vibration and high noise of the pulverizer are found, stop the machine immediately for inspection;
11. After every 40 hours of operation of the main shaft bearing, 80 grams of grease should be added, but it can only be added to 60%. After 1800 hours of operation, the bearing box cover should be removed and all the 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, never add too much grease;
12. When it is found that the output of the pulverizer suddenly drops, in addition to the factors of raw materials, it is necessary to focus on checking whether the supplementary damper is in place, whether there is air leakage in the pipeline, whether the pulse bag is blocked, whether the solenoid valve and the fan are working normally, etc.
