REDUCING THE NOISE OF VIBRATING SCREENS USING DOUBLE BODY STRUCTURE

This paper is devoted to the analysis of the working principle and the noise measuring results of vibrating screens. It is concluded that the high noise of vibrating screen is mainly caused by the high frequency disturbing forces from the driver. On the basis of the conclusion the paper then proposes a new noise control method—doube body structure, the noise reducing principle of which is studied and the effectiveness of which is illustrated by test results at the same time.
