ABSTRACT:
A crushing machine is disclosed which comprises a casing, a coarsely crushing blade which crushes scrap into coarsely crushed pieces, and a finely crushing blade which crushes the coarsely crushed pieces into finely crushed pieces. The coarsely crushing blade and the finely crushing blade are rotatably disposed in the casing, and jetting holes are formed in the coarsely crushing blade to jet compressed air radially outward from the coarsely crushing blade. Also, the jetting holes are connected to a compressed air passageway which is formed in the rotary shaft of the coarsely crushing blade. In addition, a stationary jetting hole is formed in the wall of the casing to jet compressed air towards a gap between the coarsely crushing blade and the finely crushing blade.
