International Journal of Environment and Pollution Research Vol.3, No.5, pp.24-30, December 2016
By adjusting the feed size and speed of the crusher, it's possible to minimize the rock crusher sound effects. Smaller feed size reduces the impact noise, while a slower operation speed decreases the frequency of noise produced. However, these adjustments need to be carefully managed to prevent compromising the crusher's output and efficiency.
From the recorded noise level in stone crushing clusters, it is found that the noise level is > 85 dBA from 6 a.m. to 4 p.m. when the stone crushers are running on and it is above the ambient noise threshold defined by Central Pollution Control Board in 2000. ...
