ABSTRACT:
A central shaft for a gyratory crusher, which includes a crushing head on which a first crushing shell is mounted; a frame on which a second crushing shell is mounted, which second crushing shell defines, together with the first crushing shell, a crushing gap; and a driving device, which is arranged to rotate an eccentric about said central shaft and thereby to cause the crushing head to execute a gyratory movement for crushing of material that is introduced in the crushing gap. The central shaft has a cavity in which are accommodated an anti-reverse and a torque limiter, the anti-reverse and the torque limiter being adapted for connection to said crushing head for restricting spinning.
