Gyratory crushers are also used as aggregate crushers. These types of crushers are similar to jaw crushers, but employ a cone shaped hopper with a smaller cone-shaped crushing head that gyrates around the inside of the hopper in an eccentric movement rather than rotating, crushing the source material until the particles are small enough to fall through the opening at the bottom.

Crushing in an impact crusher takes place when the stone is struck by the spinning impact bars, and by that stone being flung against an apron. When impact crushing is used, the striking of the aggregate by the spinning rotors blow bars knocks off or breaks the elongated fractures. This process is repeated by an impactor in the secondary stage.
