<p>A shredding machine for shredding vehicle tires and various other materials includes a pair of rotatable shafts and a cutting block mounted within a frame. The cutting block includes a top surface and a plurality of slots extending downwardly from the top surface and located on each side of the cutting block. The top surface of the block and each of the slots define respective U-shaped cutting edges. The shafts are rotatably mounted on the frame on opposite sides of the cutting block. Each shaft includes a plurality of cutting teeth which are spirally arranged along the length of each shaft. Each shaft may include one or more spirals of cutting teeth. The shafts are rotated in opposite directions relative to one another with one or more of the cutting teeth on each shaft being rotated through a respective slot in cutting engagement with the U-shaped cutting edge of the slot. The cutting teeth and the U-shaped cutting edges coact to shred material which is fed into the shredding machine into uniformly sized pellets. A stationary cleaning bar is mounted on the frame adjacent to each respective shaft for removing any shredded material which may cling to the cutting teeth.</p> |
