Crushing Plant Design and Layout Considerations
Crushers, screens and dust-collection fans all contribute to high noise levels. Air-cooled lubrication systems are not only noisy, but often leak oil. Well-balanced, choke-fed crushers, dust-enclosed screens and dust collector fans with silencers can keep noise levels under control. Recirculating water can be used to cool crusher lubrication

5 Best Practices for Dust Control in Manufacturing
Here are some best practices for dust management. 1. Capture the Dust at Its Source. Any effective dust control program should capture as much dust as possible and capture it at the source. This generally involves moving airborne dust particles into a hood or machine connection point, through a duct system, and then to the dust collector.
