ABSTRACT:
An apparatus for shredding waste material includes first and second cooperating shredding rotors rotatably mounted adjacent to one another in a shredding chamber. Each rotor includes a series of axially spaced toothed ripper blades removably mounted on a shaft and positioned so that the blades of one rotor interleave with the blades of the other rotor. The blades are arranged in a stacked assembly which may be removed as a unit for repair or replacement without removing the rotor shaft. A crank drive arrangement develops relative rotational oscillatory bi-directional motion between the rotors to shred material fed therebetween. The rotors are oscillated out of phase with one another so that their teeth are continuously moving at different relative angular velocities with respect to one another.
