I have summarized the above points and hope it will be useful to you.

First, the rotor of the motor is different from the rotor of the grinder. When the rotor of the motor is different from the rotor of the crusher, the crusher will easily vibrate during operation. In this situation, you may move the position of the motor left or right, or add pads under the bottom of the motor to adjust the concentricity of the two rotors.

Second, the rotor of the grinder is different. The rotor has a different center, that is, the two supporting surfaces of the palm rotor shaft are not in the same plane. The bottom surface of the supporting bearing seat can be padded with copper, or an adjustable wedge iron can be added to the bottom of the bearing to ensure that the two shaft heads are concentric.

Third, the vibration of the crushing chamber is relatively large. This situation is usually due to the difference in the coupling between the coupling and the rotor or the uneven quality of the flat hammers inside the rotor. The industry proposes that the coupling between the coupling and the motor can be adjusted in a corresponding manner according to the different types of couplings: when the quality of the hammers is uneven, each group of hammers must be selected from the beginning to make the hammers relatively symmetrical The deviation of the symmetrical hammer is reduced.

Fourth, the original average was destroyed. In this situation, a moving average test must be performed after the motor is repaired to ensure the overall average during equipment operation.

Fifth, the anchor bolts of the crusher system are loose or basically weak. According to the industry, during installation or maintenance, the anchor bolts should be evenly tightened, and a shock absorption device should be installed between the foundation and the crusher to reduce vibration.

Sixth, the broken hammer or the hard debris in the crushing chamber will also cause uneven rotor rotation, which will cause the whole machine to vibrate. Therefore, it is very important to inspect the equipment regularly, and the hammers that are important for wear should be quickly replaced. When replacing, it should be replaced symmetrically; the abnormal sound during the operation of the pulverizer should be shut down for inspection as soon as possible, and the reason should be solved quickly.
