Gyratory Crusher
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.
Gyratory Crusher vs. Cone Crusher: What's the Difference?
The gyratory crusher operates by means of a gyrating mantle, which gyrates continuously against a stationary concave surface.
