摘要： PROBLEM TO BE SOLVED: To crush a large amount of waste plastic with a small size device by enabling the crushing of a large amount of waste plastic at high speed, to carry out economical treatment and to efficiently convey small waste plastic containing a moisture content being hardly conveyed at prior art.
SOLUTION: When the waste plastic is crushed by a fixed blade and a rotation blade using a single-shaft type crusher, reduction of a crushing speed is prevented by suppressing raising of temperature of the waste plastic at crushing by making it to a deposition moisture content value of the waste plastic corresponding to a crushing treatment speed of the waste plastic per length of 1 meter of a rotor. Further, when the crushed waste plastic is conveyed, it is conveyed by a conveying device in which a plurality of moving elements are moved in a pipe.

摘要： PROBLEM TO BE SOLVED: To manufacture a high firmness coke, when high density particles are blended with coal and the resultant mixture is pyrolyzed in a coke oven, wherein the particles are made by molding waste plastics. SOLUTION: A waste plastic, which contains low temperature softening plastics i. e. polyethylene, polypropylene or polystyrene at a ratio of 50% or more in total, is used as a raw material. The waste plastic is molded by a molding method wherein a material is extruded from a nozzle by using a screw type pushing device. The waste plastic is brought to a temperature of 180-260°C in a molding apparatus, and a gas in the molding apparatus is sucked. By this operation, polyethylene, polypropylene and polystyrene are converted into a molten state, and the gas in the plastics is reduced. After compression molding the resin in that state by extruding from a 15-60 mm diameter nozzle, the extruded material is cut and then cooled by a water-cooling means within 3 seconds after cutting.

摘要： The present invention provides a reducing furnace of the rotary hearth-type and a method for reducing a metal oxide simplified in the process from dehydration to molding, according to which a moisture-rich powdery raw material is reduced at low cost. The present invention also provides an operation method whereby dusts or sludge generated in the refining or processing of metal are economically recycled. A powdery mixture having a moisture content of 100% or higher relative to the total mass of a metal oxide-containing powder and a carbon-containing powder is made into a slurry and mixed by stirring. Thereafter, the slurry is dehydrated to a moisture content of 16 to 26% and compression-molded into articles. The cylindrical or granular shaped articles having a thickness or diameter of 30 mm or less thus obtained are fed to a zone the atmospheric temperature of which is 1170 DEG C or lower in the furnace and reduced through calcination by a rotary hearth reducing furnace thereby to provide a metal.

摘要： The invention is directed to producing high-density pellets by molding waste plastic and to producing high-strength coke by mixing the pellets with coal and dry-distilling the mixture in a coke oven. As feedstock is used waste plastic that contains polyethylene, polypropylene and polystyrene, which are plastics that soften at a low temperature, at a total rate of 50% or greater. The waste plastic is molded using a molding method of extruding it from a nozzle of a screw-type stuffing machine. In the method of this invention, the waste plastic is heated to 180 - 260 °C in the molding machine and gas in the molding machine is sucked out. By this operation, the polyethylene, polypropylene and/or polystyrene are made molten and the amount of gas in the plastic is reduced. The plastic in this state is compression-molded by extrusion from a nozzle of 15 - 60 mm diameter. The plastic molding obtained is cut into chunks and cooled with a water cooler within 3 seconds after cutting.
