Abstract: A chipping apparatus includes a housing arranged about an axis of rotation and a chipping system within the housing rotating in a predefined direction about an axis of rotation. The chipping system has chipping tools that form a circular or ring-shaped chipping zone. The housing is divided into the sectors I, II, III and IV in the direction of rotation, with a material outlet being arranged in sector I. The axis of rotation of the chipping system is arranged eccentrically, with respect to a central axis of the housing, in the region of sector I or II. In this way, a uniformly widening flow channel is produced between the chipping tools and the housing, even when the housing is circular in cross-section. The constant volume increase in the flow channel toward the material outlet prevents an increasing material density, which can cause blockages in the material flow.
