PROBLEM TO BE SOLVED: To drastically reduce the possibility of failure of a blade and enhance crushing efficiency by properly discharging a foreign matter. SOLUTION: This crushing treatment apparatus 10 is provided with a crushing rotor 34 equipped with a plurality of crushing blades towards the rotation direction at the outer periphery, a fixed crushing member which is positioned at the outside of the crushing rotor 34 and has a plurality of apertures to crush the material to be crushed in cooperation with the crushing blades, a motor connected with the shaft of the crushing rotor for rotatively driving the crushing rotor by normal rotation/ reverse rotation and a driving means that drives and controls the motor. The fixed crushing member has a fixed crushing plate 30 in which a plurality of apertures are formed and which is extendable in the axis direction at the side in the reverse rotation direction of the crushing rotor 34, and a guidance plate 31 which is extendable in the axis direction in the normal rotation direction. The distance between the crushing rotor and the fixed crushing plate is sufficiently smaller than that between the crushing rotor and the guidance plate. COPYRIGHT: (C)2006,JPO&NCIPI
