  • Pellets and method for producing the same
    Publication number: 20030021991
    Abstract: Waste plastics including solid plastics, thin plastics, and foamy plastics are fed into a ring die of an extrusion molding machine. The waste plastics are either semi-melted or melted, and are then extruded onto an outer circumferential surface the ring die through die cavities. Thus, granular plastic moldings are extruded onto the outer circumferential surface of the ring die through the die cavities, and are then cut or scraped from the outer circumferential surface of the ring die. The pellets have a melt-solidified surface, and have a strength sufficient to reach a predetermine zone in a raceway of a furnace and a grain diameter sufficient to be fed at a velocity higher than a limiting velocity thereof during injection to the furnace.

  • Apparatus for disposing synthetic resinous materials
    Patent number: 6221311
    Abstract: A method for disposing synthetic resinous material comprises: dechlorinating a synthetic resinous material by heating the synthetic resinous material and decomposing the same; and supplying the synthetic resinous material into the furnace as a fuel or a reducing agent. An apparatus comprises: a chlorine removing means for dechlorinating the synthetic resinous material by heating the synthetic resinous material; and a pulverizer for pulverizing the dechlorinated synthetic resinous material, a supply means for supplying the processed synthetic resinous material into a furnace.

  • Method of blowing synthetic resin into furnace and apparatus therefor
    Patent number: 5992335
    Abstract: A method for blowing a synthetic resin material into a furnace which comprises processing film-shaped synthetic resins into a first granular resin material; crushing non-film-shaped synthetic resins into a second granular resin material; pneumatically feeding the first granular resin material and the second granular resin material to a furnace; and blowing the first and second granular resin material into the furnace.
