The vibration pulverizer generally adopts a motor directly connected to the pulverizing device, and the connection mode is simple and easy to maintain. However, if the two are not well connected during the assembly process, the overall vibration of the pulverizer will be caused.
1. The pulverizer rotor is not concentric. The reason is that the two bearing faces of the rotor shaft are not in the same plane. The copper can be padded on the bottom of the bearing housing, or an adjustable wedge iron can be added to the bottom of the bearing to ensure that the two shaft heads are concentric.
2. The anchor bolts of the pulverizer system are loose or the foundation is not strong. When installing or repairing, the anchor bolts should be evenly tightened. Between the anchor foundation and the pulverizer, shock absorbing devices should be installed to reduce vibration.
3. The hammer is broken or smashed into the room with hard debris. These will cause the rotor to rotate unbalanced, causing the whole machine to vibrate. Therefore, it is necessary to check regularly for hammers with severe wear. When replacing, it should be replaced symmetrically; if abnormal sound occurs during the operation of the crusher, stop it immediately and find the cause and deal with it in time.
Bearing overheated bearings are important accessories on the pulverizer, and their performance directly affects the normal operation and production efficiency of the equipment. During the operation of the equipment, the user should pay special attention to the noise of the bearing to the noise of the bearing part, and the abnormality should be dealt with early.
1.2 bearing blocks are uneven, or the rotor of the motor is not concentric with the rotor of the pulverizer, which will cause the bearing to be subjected to an additional load, causing the bearing to overheat. In this case, stop the machine immediately to eliminate the damage to avoid early damage to the bearing.
2. The bearing cap and the shaft are too tightly fitted. If the bearing and the shaft are too tight or too loose, the bearing will be overheated. Once this problem occurs, the friction sound and the obvious swing will occur during the operation of the equipment. The bearing should be removed at the stop. Trim the friction parts and reassemble as required.
The clogging of the pulverizer is one of the common faults in the use of the pulverizer. It may be a problem in the design of the organic tool, but it is more caused by improper handling.
1. If the discharge pipe is not smooth or the feed is too fast, the clogging machine will be blocked; if it is not properly matched with the conveying equipment, the discharge pipe will be weakened or blocked after the 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.
2. The feed rate is too fast, the load increases, 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, and the amount of feed can be controlled by adding a feeder. 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.
