Precautions for the use and maintenance of the grinder

After the grinder is installed and debugged, before the operator takes over the production and operation, please read the product manual carefully, understand the structure principle of the grinder, be familiar with the performance and operating procedures of the grinder, operate strictly in accordance with the operating procedures, and follow the operating procedures and Precautions for roving inspections.

While operating in strict accordance with the operating procedures, you must also keep in mind the following tasks:

(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 and tear of the vulnerable parts of the crusher to see if it is normal wear and tear;

(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 hammers on the hammer pin shaft of the two opposite (1800 direction) hammers is ≤1g and the two opposite (1800 direction) hammers The total weight difference of the hammers on the pin shaft is less than or equal to 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 best to install the screen with the wool side facing inward;

(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, the pulverizer should be shut down immediately for inspection;

(11) 80 grams of grease should be added to the spindle bearing 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 pulverizer 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.
