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.

Noise and Vibration Reduction of a Vibrating Screen

2012-8-30  Vibrating screens are a major noise problem in most coal preparation plants because screens are used extensively in the plants, are usually located in high traffic areas and can generate high noise levels (Rubin et al., 1982).

Noise and Vibration Reduction of a Vibrating Screen

Workers in coal preparation plants, where vibratingscreens are significant noise sources, are often exposed tosound levelsexceeding90 dB(A). The National Institutefor Occupational Safety and Health, a major coal company,and a vibrating screen manufacturer conducted acooperative study of vibrating screen noise. Rubberisolators reduced sound levels by 1 dB. Urethane screenpanels did not reduce sound levels in this case. Drive noisewas determined to be the dominant noise

Noise controls for vibrating screen mechanisms

2012-8-30  To characterize noise sources, NIOSH researchers performed sound pressure level (SPL) measurements on a vibrating screen at their Office of Mine Safety and Health Research laboratory in Pittsburgh. The results show that the entire screen contributes to noise below 1 kHz, and the vibration mechanism housings are most significant above 1 kHz.
