PURPOSE:To eliminate the central concn. of refuse, to avert an overloading state and to stably crush and discharge the refuse by using a part of screw vanes as cutting blades and providing the inside surface of a casing opposite to these cutting blades with stationary blades at a prescribed spacing from the cutting blades. CONSTITUTION:A part of the screw vanes 4a, 4b of screw shafts 2a, 2b of twin screws of this refuse supplying device are formed as the cutting blades 6 having twist angle larger than the twist angle of the screw vanes 4a, 4b. The inside wall of the casing 8 facing these cutting blades 6 is provided with the stationary blades 7 for crushing the refuse by the interaction with the cutting blades 6. The two screws are rotated respectively relatively outerward to crush the refuse by the cutting blades 6 and the stationary blades 7. |
