Crusher clogging is one of the common failures in the use of pulverizers, perhaps the design of the machine itself, but more due to improper use. The main reasons for the blockage problem may be the following:
1. The feed rate is too fast and the load is increased, causing blockage. During the feeding process, always pay attention to the large deflection angle of the ammeter pointer. If the rated current is exceeded, it indicates that the motor is overloaded and overloaded for a long time, which will burn the motor. In this case, the door should be immediately reduced or closed, and the way of feeding can be changed. The feeder is controlled to increase the amount of feed. There are two types of feeders: manual and automatic. Users should select the appropriate feeder according to the actual situation. Due to the high speed of the pulverizer, the load is large, and the fluctuation of the load is strong. Therefore, the current when the pulverizer is working is generally controlled at about 85% of the rated current.
2. If the discharge pipe is not smooth or the feed is too fast, the pulverizer will be blocked. If the mismatching with the conveying equipment will cause the wind of the discharge pipe to weaken or block without wind. After the fault is detected, the conveying equipment whose delivery port is not matched should be cleared first, and the feeding amount should be adjusted to make the equipment operate normally.
3, the hammer piece, aging, screen mesh hole closed, broken, the water content of the crushed material is too high will cause the crusher to block. The broken and severely aged hammers should be regularly updated to keep the pulverizer in good working condition, and the screen should be inspected regularly. The moisture content of the pulverized material should be less than 14%, which can not only improve the production efficiency, but also prevent the pulverizer from being clogged. Enhance the reliability of the pulverizer work.
