PROBLEM TO BE SOLVED: To provide a bucket type disintegrator increased in destructive power by providing a destructive function to both members of a rotary disintegrator and the inverted truncated cone-shaped frame body provided outside the rotary disintegrator. SOLUTION: The inverted truncated cone-shaped disintegrator frame body, wherein a plurality of radial vertical frames are connected by one or more stages of upper and down horizontal frames, is fixed to the inside of a bucket-shaped main body frame and the rotary disintegrator having one or more stages of protruded crushing teeth provided thereto is arranged in the disintegrator frame body. In the disintegrator thus constituted, the vertical frames of the disintegrator frame body are spirally arranged so as to be inclined in the direction reverse to the rotary direction of the rotary disintegrator and vertical frames are constituted of a square steel material. An inner bottom plate having a falling hole is fixed under the rotary disintegrator and a plurality of crushing projections different in protrusion length are formed to the outer bottom surface of the rotary disintegrator opposed to the inner bottom plate. The crushing teeth of the rotary disintegrator are made gradually long from a lower stage to an upper stage in lateral protrusion length. COPYRIGHT: (C)2004,JPO
