摘要

An apparatus for processing mineral materials comprises a feed device (4) having an opening for feeding the material; at least two parallel rotating shafts (14, 15) connected with a drive device, the shafts having a counter rotating movement; and wedge elements (23) for producing a chamfering effect on the brittle components to be crushed. The wedge elements are connected to the shafts to form a gap (5). - Preferred Features: The shafts are arranged in a passage which is arranged on the lower side of the feed device. Each shaft has several wedge elements to produce the chamfering effect. The wedge elements can be detached from the shafts.
