Rock Crushing Process in Mining
First the rock will enter the crushing chamber and drop as far as the angle of the crushing surface will allow it to. The crusher "breaks it and the fine material produced will drop through the gap between the mantle and the liner as it opens. The coarse material that can't fall through will remain to be crushed with the next gyration.

The six main steps of iron ore processing
Six steps to process iron ore. 1. Screening. We recommend that you begin by screening the iron ore to separate fine particles below the crusher's CSS before the crushing stage. A static screen is used to divert the fine particles for crushing. This step prevents overloading the crusher and increases its efficiency.
