ABSTRACT:
The present invention is a universal shredder for shearing and cutting bulk material into pieces of a predetermined size. The apparatus has rotating shearing members that pull the bulk material down between the shearing members and shearing it into sheared pieces. Grooves formed by helically-shaped members extending from the bodies of the shearing members carry the sheared material downward to a main cutting member where the sheared material is cut by cutting teeth removably attached to the helically-shaped members as the cutting teeth pass through notches in the main cutting member. The cut pieces fall or are pushed through the notches in the main cutting member and pass through apertures in a screen positioned beneath the shearing members. The size of the apertures can be adjusted by moving the screen which is supported by a series of parallel ribs with lugs attached in a pattern that matches the pattern of the apertures of the screen.
