An inner shell (4), which is intended for use in a 5 gyratory crusher and which during crushing will rotate around its own centre axis (CL) in a first direction (R1), has at least one additional crusher surface (40). The additional crusher surface (40) has, in horizontal projection and as seen in the first direction (R1), a 0 decreasing distance to said centre axis (CL). Large objects (S) can be introduced between the additional crusher surface (40) and an outer shell (5) near a first end (46) of the additional crusher surface (40) in order to, near a second end (48) of the additional crasher surface (40), be squeezed between the additional crusher surface (40) and the outer shell (5) and be crashed. |
