Crushing is accomplished by compression of the ore against a rigid surface or by impact against a surface in a rigidly constrained motion path. Crushing is usually a dry process and carried out on ROM ore in succession of two or three stages, namely, by (1) primary, (2) secondary, and (3) tertiary crushers. 13.3.1.1 Primary Crusher

The settings are based on the crushing characteristic of the material being fed and the desired final product size and size distribution. There are no hard and fast rules. But in general (very very generally, with many exceptions) crushers will do a 4 to 1 up to a 10 to 1 reduction (mostly dependent on the hardness and friability).
