NOVELTY - Material of used paper crushed piece and waste-plastic crushed piece are detected separately by irradiating with near-infrared rays, and each heat energy released is separately calculated. Composite supply of separately stored used paper crushed piece and waste-plastic crushed piece is carried out at preset ratio and extrusion-molded, to obtain the refuse paper and plastic fuel.    USE - For manufacturing refuse paper and plastic fuel used as alternative of fossil fuel of kiln for cement baking, and alternative of coke for blast furnace, boiler and drying machine.    ADVANTAGE - The method enables manufacture of refuse paper and plastic fuel of favorable quality. Uniform release of heat energy of refuse paper and plastic fuel is enabled.    DETAILED DESCRIPTION - Used paper and waste plastic are crushed separately. The material of used paper crushed piece and waste-plastic crushed piece are detected separately by irradiating with near-infrared rays, and the heat energy released into the material is multiplied with the number of used paper crushed piece subjected to material detection, and waste-plastic crushed piece, and each heat energy released is separately calculated. Composite supply of separately stored used paper crushed piece and waste-plastic crushed piece is carried out at a ratio corresponding to the desired heat energy released based on the calculated heat energy released and extrusion-molded, to obtain the refuse paper and plastic fuel. The process is carried out at preset interval of time.    An INDEPENDENT CLAIM is included for manufacturing equipment of refuse paper and plastic fuel, which has feed conveyor (1) for supplying used paper or waste plastic, crusher (2) for crushing used paper or waste plastic, material detectors (3A and 3B) for detecting the material of crushed used paper pieces and waste plastic crushed pieces, respectively, heat energy-released calculating units (I and II) for calculating the released heat energy of used paper crushed pieces and waste plastic crushed pieces based on detected results of detectors (3A and 3B), respectively, feeders (10A and 10B) for storing and supplying used paper and crushed pieces and waste plastic crushed pieces, ratio control unit for controlling ratio of feed rate of feeders (10A and 10B), and molding machine (14) for carrying out extrusion-molding of mixture.    DESCRIPTION OF DRAWING(S) - The figure shows the outline block diagram of the manufacturing equipment of refuse paper and plastic fuel.    feed conveyor (1)    crusher (2)    material detectors (3A,3B,13A,13B)    feeders (10A,10B)    molding machine (14)    thermometer (15)    sprinkler system (16)    moisture content measurement unit (22)
