PROBLEM TO BE SOLVED: To provide an RDF (refuse-derived fuel) forming machine to be used in making domestic wastes or industrial wastes into a solid fuel (RDF) by a stable operation through such a scheme that, in addition to the static pressure by a press roller, a vibrator is placed to apply a dynamic (vibratory) pressure to enhance a crushing force for hard-to-treat feedstocks and to reduce the passage resistance of the wastes passing the die of a ring to cause no clogging at the die. SOLUTION: This RDF forming machine 1 includes a hydraulic unit 10 functioning to apply static pressure force onto a press roller 8; wherein, dynamic (vibratory) pressure force is further applied onto the press roller 8 by the action of a vibrator, i.e., an electromagnetic vibrator 13 or small-sized electrohydraulic vibration generator.
