ABSTRACT:
An energy efficient "large bore" dual auger shredder that is adaptable to waste of different characters and constituents and is capable of conveniently handling large scale bulk is described. Counter-rotating tapered auger screws are mounted on parallel axes in a frame that includes a hopper beneath the axis of the screws that on each side essentially corresponds to the conical taper of the screws. A central exit opening is formed in the hopper bottom beneath the screw axes.
