PROBLEM TO BE SOLVED: To provide a rotary crusher capable of suitably crushing even wood, or the like, without scattering the crushed powder thereof to the circumference. SOLUTION: This rotary crusher is constituted so that a crusher rotor 15 rotationally driven by a drive source 8 is provided in a casing 2 having an upper charging port 3 and a lower discharge port 4 formed thereto. An exhaust port 14 is formed to the side wall plate 2A of the lower part of the casing 2 and the exhaust port 14 and an exhaust fan 28 are connected through an exhaust duct 29. Air streams flowing from the upper charging port 3 and the lower discharge port 4 are formed in the casing 2. As a result, crushed powder is not blown up from the upper charging port 3 and the charging of an object to be crushed into the upper charging port 3 can be suitably performed. COPYRIGHT: (C)2004,JPO
