Abstract: An inner shell, which is intended for use in a gyratory crusher and which during crushing will rotate around its own center axis in a first direction, has at least one additional crusher surface. The additional crusher surface has, in horizontal projection and as seen in the first direction, a decreasing distance to the center axis. Large objects can be introduced between the additional crusher surface and an outer shell near a first end of the additional crusher surface in order to, near a second end of the additional crusher surface, be squeezed between the additional crusher surface and the outer shell and be crushed.

Abstract: A fastening mechanism comprising a pin having a shank coupled to the head at a first end of said shank. A metallic pin-lock is provided having a base portion coupled to a resilient pin-engaging portion. The shank has a circumferentially-formed notch at a second end, said notch being adapted to receive the resilient pin-engaging portion. A resilient member is coupled to the base portion of the metallic pin-lock and to a mobile phone housing. A retainer is provided for housing said fastening mechanism inside the mobile phone housing. Upon insertion of the pin into the pin-lock, the pin is adapted to move the resilient pin-engaging portion a predetermined distance until the resilient pin-engaging portion engages the circumferentially-formed notch. The pin-lock is adapted to be removed from the pin via a magnet attracting at least a portion of the pin-lock away from the pin.
