1. The feeding speed is too fast, the load becomes larger, causing blockage. In the feeding process, it is necessary to pay attention to the large offset angle of the ammeter pointer in time. If it is higher than the rated current, it will reflect that the motor is overloaded. If it is overloaded for a long time, the motor will be damaged. In such a situation, the feed gate should be lowered or closed in time, and the form of feed can also be changed, and the feed amount can be controlled by increasing the feeder. There are two types of feeders: manual and automatic. Users should choose the appropriate feeder according to the actual situation. Due to the high speed of the food grinder, the large load, and the strong fluctuation of the load. Therefore, the current of the food grinder is generally controlled at about 85% of the rated current.

2. The discharge pipe is not smooth or the material is blocked too fast, which will block the air outlet of the pulverizer. Mismatching with the conveying equipment will cause the discharge pipe to be weakened or blocked after no wind. After checking the fault problem, you should first clear the delivery port to change the unmatched conveying equipment, adjust the incoming and outgoing material quantity, and make the equipment operate normally.

3. The hammer is broken and old, the screen mesh is closed and worn, and the moisture content of the crushed material is too high, which will surely block the crusher. The broken and severely aged hammers should be updated regularly, the good working efficiency of the food grinder should always be maintained, and the screen should be checked. The moisture content of the crushed materials should be less than 14%, so that the productivity can be continuously improved, and The food pulverizer is not blocked, and the safety and reliability of the pulverizer is strengthened.
