ABSTRACT:
The invention comprises a method and apparatus for separating and recycling plastics from plastic parts containing, for example, light metal, rubber, non-ferrous metals and labels of any type attached. The plastic parts are also reduced to selected sizes. The method and apparatus basically includes shredding the plastic parts so as to reduce the plastic parts into a first reduced size of plastic pieces; moving the shredded plastic pieces to subject them to a magnetic device so that light metal material is removed from the shredded plastic pieces; subjecting the plastic pieces to a grinder device to reduce the plastic pieces to smaller pieces; subjecting the smaller plastic pieces to a sufficient high pressure steam to remove contaminate materials from the plastic pieces; and drying the plastic pieces and contaminate materials and separating the plastic pieces from the contaminate materials.
