The maximum crushing ratio of coarse crushing is about three. The main force in the coarse crushing of ore is crushing. Typical coarse crushing equipment includes jaw crusher, gyratory crusher, and roller-tooth crusher. Ore medium crushing is a process of crushing ore blocks with a feeding particle size of 125–400 mm to 50–100 mm.

The majority of gyratory crushers are used as primaries, i.e. they receive the initial feed from the mine or quarry. The same type of crusher with chamber modifications is used as a secondary crusher, particularly when following a large primary crusher. The fine-reduction gyratory crusher can also be used for tertiary crushing.
