摘要： A method of separating solid waste materials, in the form of dried particles of substantially uniform size, into constituent materials on the basis of density, with primary stage processing utilizing one or more fluidized bed and cyclonic separator assemblies to separate materials on the basis of density, is provided by the invention. Secondary stage processing utilizing combinations of vibratory conveyors and melt separation assemblies, is also provided. As the waste materials move through the separator assemblies the initial stream is further refined into a plurality of streams of increasingly specific densities as a result of air flow separation of lighter particles from heavier particles in each assembly. Further refined separation may be achieved through the use of vibratory conveyors and melt separation. Air flow separator assembly apparatus and melt separator apparatus, including a plurality of belts each heated to a selected temperature for temporary adhesion of plastic particles thereto, is also provided by the invention.

摘要： Thermoplastic articles are removed from a mixed waste stream and are sorted by heating the articles along the path of the waste stream to different softening temperatures of the different types of articles before the articles contact the separating bodies which have surface formations that are forced into the softened zones of the thermoplastic article so that the articles are impaled upon the body. The articles are then removed. The force with which the softened articles are impaled is obtained by a support or counterforce member juxtaposed with the separating bodies.

摘要： Apparatus and process for removing unwanted foreign material from particulate material. The apparatus and process find particular application in the pulp and paper industry to remove contaminating plastic material from wood chips. The apparatus includes a transporting conveyor for moving the particulate material between a inlet area and an outlet area and a vibrating motor for vibrating the conveyor to sort the particulate material and the foreign material. Heated rollers heated to a temperature sufficient to render the foreign material tacky are applied to the sorted material and cause the foreign material to adhere thereto such that the foreign material is extracted from the particulate material which is delivered to the outlet area.
