Rock Crushing Process in Mining. Let’s follow a rock through a crushing cycle to see what variables will have to be controlled. First the rock will enter the crushing chamber and drop as far as the angle of the crushing surface will allow it to.

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
