Introduction. The main air pollution problem in a mining area is due to the presence of particulates, which may be coal, soil or rock dust1. Strip mine air pollution source can be divided into two categories, point sources and fugitive sources. Points sources typically include stationary exhaust stacks2.

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.
