Mill liners protect the mill shell from wear and transfer energy to the grinding charge. Careful balance is needed to optimise these differing requirements, as poor liner design has detrimental effects on milling performance – and on mill liner life. Mill liners developed by Multotec include Ball Mill Liners, SAG Mill Liners, AG Mill Liners.The permissible sound level view of point was 24 ft at day time The acceptable sound limit set by Department of Environments is 60 dBA at mixed area This value exceeds in every stone crushing plant at Jaflong area Key Words Noise Level Crushing Machine Decibel Permissible Sound Human Health UCTION Noise is generated from sound. Detail.The assessable noise level from Edna May operations are 43 dB(A) during night time periods. Therefore, there would be an exceedance with the regulatory criteria of 8 dB(A). Noise control in the form of bunding would be limited in its effectiveness in reducing noise levels.
