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

The philosophy in the development of the MRRC grinding simulation package was to build interactive software that could be used as an inexpensive means of providing a semi-quantitative check on a grinding mill design. In addition the software is designed to “slot in” to a general mineral processing package now undergoing development at the MRRC.

The three basic types of dust-control system currently used in minerals extraction and processing operations are: airborne dust capture. Dust-collection systems use ventilation principles to capture the dust-filled airstream and carry it away through ductwork to the collector. Wet dust-suppression techniques use water sprays to wet the fugitive

A common method of dust control at mineral processing operations is the use of wet spray systems to add sufficient moisture to contain the dust but not more than what is required, or otherwise known as DEM ( Dust Extinction Moisture). Wet dust control can be done to the process material before crushing, after crushing, or both.
