Vibration pulverizer generally adopts motor direct connection pulverizer, this connection is simple and easy to maintain. However, if the two are not well connected in the assembly process, it will cause the overall vibration of the mill.
(1) The motor rotor is different from the mill rotor. The position of the motor can be moved left or right, or the foot surface of the motor is added to adjust the concentricity of the two rotors.
(2) The mill rotor different heart. The reason is that the two supporting surfaces of the supporting palm rotor shaft are not in the same plane. The copper leather can be padded on the bottom surface of the bearing seat, or an adjustable wedge iron can be added at the bottom of the bearing to ensure that the two shaft heads are concentric.
(3) The vibration of the crushing chamber is relatively large. The reason is that the coupling and the rotor connection is different or the rotor inside the flat hammer mass is not uniform. According to different types of coupling can take the corresponding method to adjust the coupling and the motor connection: when the quality of the hammer is uneven, must re-match each group of hammer, so that the relative weight of the hammer, so that the relative weight of the hammer error is less than 5G.
(4) The original balance is destroyed. Motor repair must be done after the dynamic balance test, in order to ensure the overall balance.
(5) The anchor bolt of the crusher system is loose or the foundation is not strong. When installing or maintaining the anchor bolt, it is necessary to fasten the anchor bolt evenly. Between the foundation and the crusher, the shock absorber should be installed to reduce the vibration.
(6) Hammer break or smash indoor hard debris. These will cause the imbalance of the rotor rotation, and cause the vibration of the whole machine. Therefore, to check regularly, for serious wear hammer piece. In the replacement, symmetric replacement; The abnormal sound in the operation of the shredder should be stopped immediately and checked to find the reason for timely treatment.
(7) The connection between the crusher system and other equipment is not consistent. For example, improper connection of feed pipe and discharge pipe will cause vibration and sound generation. Therefore, these connection parts, should not be hard connection, the best use of soft connection.
