Abstract: A crusher includes a base, a cylinder pivoted to the base, cutting portions arranged on the cylinder. A crusher cutter assembly is further provided, including: a cutter base, for being assembled to the crusher, having receiving slots including an abutting recess and a bottom portion. A crusher cutter is further provided for assembling on the cutter base. The crusher cutter includes: two corner portions, disposed on two sides thereof, for being inserted in the abutting recess and fixed on the cutter base, two sides of the corner portion abutting against the abutting recess; two abutting portions, disposed on two opposite sides of the crusher cutter, for being positionably abutting against another crusher cutter; wherein when the crusher cutter is fixed on the cutter base, a part of the corner portion protrudes beyond the cutter base and is alternatively shifted with a part of the cutting portions.

Abstract: A recycling machine includes a main frame, a sieve barrel, a pressing cylinder, an end disk, a propeller shaft, a cutting device and an output device. The sieve barrel has a receiving chamber and a plurality of sieving apertures. The pressing cylinder has a receiving space and a plurality of toothed pressing portions. The end disk has a plurality of extruding holes. The propeller shaft has a first helical blade, a buffering portion and a second helical blade. Thus, the reused materials are forced into and revolved in the sieve barrel by rotation of the first helical blade to proceed a first-stage dehydration process, and are compressed in the buffering space between the buffering portion and the receiving chamber to proceed a second-stage dehydration process so that the reused materials are dehydrated completely.
