ABSTRACT:
A shredder having a hopper for funneling material to the cutting blades of the shredder is provided with a ram assist within the hopper to push material into the cutting blades. The ram is shielded from the material passing through the hopper by an intermediate partial wall extending from the infeed of the hopper to the mid portion of the hopper. In its retracted position the ram is positioned behind the partial wall out of the stream of material passing through the hopper. In its extended position the ram is proximate the outfeed of the hopper within the flow of material. A ram controller senses the load upon the cutting blades of the shredder and selectively activates and deactivates the ram.
