PURPOSE: A production device and a production method of an RDF(Refused Derived Fuel) are provided to obtain an RDF of high quality by improving the combining force of different materials. CONSTITUTION: A crusher(100) contains a housing to insert waste, a pair of crushing rotors to be supported inside the housing to be rotatable and a crushing motor to drive the crushing rotors. The crusher shatters waste through the crushing rotors and discharges shattered waste. A pre-forming processor(300) contains a case, a pair of mixing rolls(310,310a) to be fixed inside the case and an extruding motor to drive the mixing rolls. The pre-forming processor receives the crushed materials from the crusher and discharges by extruding and mixing. A forming device(400) contains a cylinder to enter the extruded material and to discharge through a forming slot, an injection screw to be rotated by arranging inside the cylinder, an injection motor to rotate the injection screw and a cutter(420) to pass through the forming slot by installing in the rear side of the forming slot. The forming device discharges the extruded material as a solid fuel through the forming slot by pressurizing through the injection screw and cuts the solid fuel at regular intervals. Thereby, the crushing force is increased.
