Mill blockage is one of the common faults in the use of mill, our Fangyuan machinery summarized the following points for your reference.
(1) Hammer fragment, aging, screen hole closure, tattered, crushed material water content is too high will make the crusher blocked. The broken and severely aged hammer should be regularly updated to maintain the good working condition of the crusher, and the screen should be regularly checked, and the water content of the crushed material should be less than 14%, which can improve the production efficiency, but also make the crusher not blocked, and enhance the reliability of the mill.
(2) The feed speed is too fast, the load increases, causing blockage. In the feeding process, we should always pay attention to the ammeter pointer deflection Angle is large, if the rated current is exceeded, it indicates that the motor is overloaded, long-term overload will burn the motor. In this case, the feed door should be reduced or closed immediately, and the feeding method can also be changed to control the feed amount by increasing the feeder. There are two kinds of feeders, manual and automatic, and users should choose the right feeder according to the actual situation. Due to the high speed of the mill, the load is large, and the load volatility is strong. Therefore, the current of the mill is generally controlled at about 85% of the rated current.
(3) The discharge pipe is not smooth or the feed is blocked too fast, which will block the mill tuyere; Improper matching with the conveying equipment will cause the wind of the discharge pipeline to weaken or block after no wind. After finding out the fault, it should first clear the delivery port to change the mismatched conveying equipment, adjust the feed amount, so that the equipment can operate normally.
