PCT No. PCT/JP94/01382 Sec. 371 Date Feb. 19, 1997 Sec. 102(e) Date Feb. 19, 1997 PCT Filed Aug. 22, 1994 PCT Pub. No. WO96/05912 PCT Pub. Date Feb. 29, 1996A chain beating type crusher includes a crusher vessel (3), a shaft (7) provided centrally thereof and capable of being rotated at a high speed, and a plurality of beating chains (11) provided in a plurality of axially spaced-apart stages in each of which a plurality of radially spaced-apart chains are formed on the shaft. With high speed rotation of the shaft the beating chains in the individual stages are caused to undergo high speed revolution to form respective bearing zones. In order to return an object scattered toward the inner surface of a peripheral wall (4) of the crusher vessel back to the beating sone, a plurality of guide members (15) are mounted on the inner surface and each have a surface inclined toward the beating zones in the direction of revolution of the beating chains. The beating chains are mounted on the shaft such that they are each positioned in correspondece to the mid position between adjacent ones of them in the next stage. Each of them is coupled to an independent support bar (13) which is fitted in a recess provided in a chain holder means (14) secured to the outer periphery of the shaft. A rotary disc (16) is provided for rotation about its shaft in the lowermost portion of the crusher vessel, and a plurality of scrapers (17) are provided on the rotary disc to cause the crushed object to be led downward and pushed to the outside of the peripheral wall of the crusher vessel.
