Abstract
The apparatus for separating plastic from paper fibers includes conveying means for initially passing contaminated paper while removing waste, adding water to the flow of plastic contaminated paper for converting the paper to a pulp condition, agitating the water and paper pulp to release plastic material so that the paper pulp will more easily release the plastic material, directing the paper pulp to a dewatering step before grinding in a hammer mill while grinding the released plastic material to be used as a fuel for creating a drying atmosphere in the hammer mill, and packaging the paper from the hammer mill in bales.
