The vibrating screen is composed of a vibrating motor plus a bottom frame, a screen and related accessories. Some noise will appear during the production operation, especially when the vibrating screen is in an abnormal situation, the noise will be greater, which will cause great problems to the production environment. At the same time, it also affects the quality of the vibrating screen.
