Noise Causes and Solutions of Vibrating Screen

2018-6-28  Vibrating screen noise source: 1.Eccentric shaft: The vibrating screen works by relying on the centrifugal force of the eccentric block to generate the vibration force. If the eccentric force deforms the eccentric shaft to produce a bend, the relative deflection of the inner and outer bases of the bearing will occur, and the trajectory of the rolling body will change, and thus increase.
