Multiple Noise Sources Rank Ordering – Vibrating Screen Example Screening noise: Noise generated by the flow of material due to coal-coal, coal-chute, and coal-screen impacts Drive noise: Noise radiated by the vibration mechanism housings, screen sides, and the building due to excitation by the gears, bearings, and eccentric weights of the ...2MB
where machines are required to be used in a cost-effective way. Operation The screening process is continuous. The machine operates dust free and with low noise levels. The hookstrip screen can be easily lifted upwards out of the machine once the retaining device has been released. The angle of the screen deck can be set at between 2° and 5°. The direction of oscillation is achieved through configu-ration of the vibrators.
offsite human noise receptors from mining project’s noise and/or vibration. Screening is required at all new mines, and also at existing mines if there is a proposed change to the mine plan that is likely to result in a new source of noise or vibration or an increase in existing noise or vibration levels. 184.108.40.206.
