Abstract
A device for comminuting scrappable feedstock by way of cutting or shear-cutting is provided that includes at least one rotor situated within a housing. The rotor has a plurality of rotary disks which are situated at an axial distance from each other, forming spaces, and which are fitted on their circumferences with comminuting tools which interact with additional comminuting tools to perform the comminution work. Stationary scraping elements extend into the spaces in the radial direction. To achieve a largely unhindered flow of stock through the device, it is proposed according to the invention to situate the stationary scraping elements in the dead zone of the at least one rotor with regard to the direction of stock flow.
