  • Gyratory crusher, outer shell intended therefore and methods for mounting and dismounting the outer shell
    Patent number: 8047460
    Abstract: A gyratory crusher has an outer shell, which is attachable in a frame having a frustoconical supporting surface, which is facing obliquely downwards and inwards. The outer shell has on the outer surface a collar, which has outer lugs, which are movable, from below, past the supporting surface and between inner lugs of a ring. The inner and outer lugs have mutually corresponding contact surfaces, which are adapted, by relative rotation of the ring and the outer shell, to be positioned opposite each other and, upon lifting of the ring, to lift also the outer shell so that a lower portion of the outer shell abuts the supporting surface of the frame. The contact surfaces of the inner and outer lugs are arranged such that lifting of the ring causes the outer lugs to be lifted by means of the inner lugs and brings the inner and outer lugs into radial abutment against each other.
