Run-of-mine ore is usually too large to be useful for construction or metallurgy. Large particles must be reduced to specific sizes to either comply with aggregate sizing regulations, or facilitate mineral liberation; therefore, in the aggregates and mineral processing industries, run-of-mine ore is broken in crushing circuits by cone crushers.

Ore entering the mill from the mine (run-of-mine ore) normally contains a small proportion of material that is potentially harmful to the mill equipment and processes. For example, In the crushing stage, large pieces of iron and steel broken off from mine machinery can jam in the crushers and even cause damage to the crusher machines.

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.
