Clearing Blocked Crushers

Gyratory Crusher A gyratory crusher breaks rock by squeezing the rock between an eccentrically gyrating spindle, which is covered by a wear resistant mantle, and the enclosing concave hopper. As oversize rock enters the top of the gyratory crusher, it becomes wedged and squeezed between the mantle and hopper.
