Abstract
An inner shell has a first part of a lug-notch arrangement, which first part is arranged to co-operate with a second part of the arrangement to prevent rotation of the inner shell relative to a crushing head. The inner shell has a contact surface in its upper portion and is arranged to be pressed towards the lower portion of the crushing head by a pressing force which is obtained by tightening at least two threaded bolts, which are arranged in the upper portion of the crushing head such that their longitudinal direction is substantially parallel to the symmetry axis of the crushing head.
