Apr 07, 2016 A cone crusher is punished during every minute of operation. It squeezes a dense mass between heavy castings until the mass disintegrates. It impacts and abrades material until it yields to the applied forces. It rumbles and vibrates and bangs as its core shaft spins eccentrically to capture and destroy chunks of stone.

Crushers All crusher types for your reduction needs

Primary crushing with gyratory crushers. The primary gyratory crusher offers high capacity thanks to its generously dimensioned circular discharge opening (which provides a much larger area than that of the jaw crusher) and the continuous operation principle (while the reciprocating motion of the jaw crusher produces a batch crushing action).
