NOVELTY - Producing high purity flammable refuse derived fuel from landfill, comprises e.g. mixing high purity flammable waste with low purity flammable waste from landfill waste, introducing mixed flammable waste into a hopper, compressing, crushing the compressed flammable mixed waste in first crushing device, passing crushed flammable mixed waste through a magnetic separator, screening steel materials by a magnetic conveyor belt, separating debris and sediment in the flammable mixed waste, mixing with dry carbide, compressing unmolded flammable waste, and packaging.    USE - The method is useful for producing high purity flammable refuse derived fuel from landfill (claimed).    ADVANTAGE - The method is environmentally friendly.    DETAILED DESCRIPTION - Producing high purity flammable refuse derived fuel from landfill, comprises (S1) mixing high purity flammable waste including waste synthetic resin, waste tires, waste plastic and general household waste with low purity flammable waste obtained from landfill waste, (S2) introducing the mixed flammable waste into a hopper, primarily compressing in a compressing rotary drum, and secondarily compressing while transferring on a horizontal and inclined conveyor belt, (S3) primarily crushing the compressed flammable mixed waste with wave rods in a first crushing device formed with upper and lower circular rotary blades rotatably mounted vertically staggered, (S4) passing crushed flammable mixed waste through a magnetic separator by transferring on the conveyor belt, and secondarily crushing the crushed flammable mixed waste in a second crushing device formed with upper and lower circular rotary blades rotatably mounted vertically staggered, (S5) screening steel materials by a magnetic conveyor belt while transferring the secondarily crushed flammable mixed waste on the conveyor belt, and drying and primarily separating stone/rock in the flammable mixed waste by hot air from heaters, (S6) secondarily separating by removing debris and sediment remaining in the flammable mixed waste while rotating internal rotating body mounted on secondary drying sorter, sorting standard large flammable mixed waste, and returning to the first crushing device, (S7) separating debris and sediment in the dry sorter, and mixing dry carbide e.g. dry carbonized rice husk briquettes lime powder and flammable mixed waste to increase calorie and to reduce moisture content of the crushed flammable mixed waste, and (S8) compressing unmolded flammable waste, and packaging. An INDEPENDENT CLAIM is also included for a device for producing high purity flammable refuse derived fuel from landfill, comprising the horizontal conveyor belt for horizontally transferring flammable mixed waste at bottom of input hopper for mixing and introducing high purity flammable waste including waste synthetic resin, waste tires, waste plastic and general household waste with low purity flammable waste obtained from landfill, the compressing rotary drum attached to lower end of the input hopper for primarily compressing while rotating flammable mixed waste transferred by the horizontal conveyor belt, an inclined conveyor belt formed inclined forwards on upper end side of the horizontal conveyor belt for secondarily compressing flammable mixed waste transferred by the horizontal conveyor belt, the first crushing device formed with circular rotary blades fixed with diamonds engaging alternately at rotating shaft formed vertically to crush flammable mixed waste compressed by the horizontal and inclined conveyor belt, the magnetic separator for separating steel materials installed in a vertical direction to the conveying direction such that steel materials mixed with flammable mixed waste transferred by the conveyor belt is separated by an electromagnet, the second crushing device formed circular rotary blades engaging alternately at rotating shaft formed vertically to crush flammable mixed waste transferred by the conveyor belt, a further magnetic separator formed on input conveyor belt to separate remaining steel materials mixed with flammable mixed waste and to transfer flammable mixed waste crushed by the second crushing device to the conveyor belt and the input conveyor belt, the heater at lower portion of the input conveyor belt for drying flammable mixed waste with hot air while separating stone/rock mixed in the flammable mixed waste transferred by the input conveyor belt, a first dry sorter perforated with several through holes at outer peripheral surface and mounted with inner rotating body internally to separate debris and sediment remaining in the flammable mixed waste from the heater, the second dry sorter for identifying mixed waste of less than or equal to 50 mm and sorting debris, a dry carbide mixture feeding unit for mixing dry carbide e.g. dry carbonized rice husk briquettes lime powder and flammable mixed waste discharged from the second dry sorter, and a compressing and packaging unit for compressing and packaging unmolded flammable waste discharged from the feeding unit.
