Noise reduction of chain conveyors for underground coal

2005-8-11  Results of a three‐phase program are presented, during which methods of reducing the operator sound level of coal chain conveyors were examined. The three phases were (1) the identification and quantification of important noise mechanisms, (2) an exploration of several alternative methods to reduce the sound level, and (3) selection and implementation of a set of noise control techniques

Plant Engineering Limiting noise from conveyor rollers

2003-12-10  The noise reduction that might be expected from retrofitting conveyors with rollers having tapered hex shafts and precision bearings has been documented. A large facility with a heavy concentration of conveyors monitored the results of such a retrofit over 6 mo. Noise level readings were taken at 4 ft above floor level to simulate what an
