ABSTRACT:
A self tightening mantle retention assembly for a conical crusher. The self tightening assembly includes a locking bolt or nut provided with external threads for engaging in internally threaded bore in the head of the crusher. The locking bolt is provided with a central bore for receiving a central bolt, the threads of which engage an internally threaded aperture formed in the head or a block secured to the upper bearing supporting the head to apply a further compressive force to the locking bolt. The threaded engagement between the locking bolt and the head and between the bolt threads and the threaded aperture in which they are received, are formed such that the torque applied to the locking bolt by the crushing action on the mandel tends to further tighten the locking bolt to secure the mantle on the head of the crusher.
