The additional crusher surface (40) has, in horizontal projection and as seen in the first direction (Rl) , 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 crusher surface (40) , be squeezed between the additional crusher surface (40) and the outer shell (5) and be crushed.
