Abstract

A grinding apparatus for forward feeding material in a drum in which the grinding apparatus has a circular grinding track therein. The drum is driven in rotation at a speed such that material therein is held on the circular grinding track by centrifugal force. A knife is positioned in an upper descending portion of the drum for detaching material from the circular grinding track. A deflecting plate is disposed beneath the knife so as to receive materials detached by the knife and to divert the detached materials toward the output of the drum. The knife is disposed such that the knife has an active face forming an angle of between +15.degree. and -50.degree. with a radial plane extending between a horizontal axis of the drum and an edge of the active face.
