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.
