CHAIN BEATING TYPE CRUSHER

摘要

A chain beating type crusher comprises a rotating shaft (7) vertically provided centrally of a crusher vessel (3) and adapted to rotate at high speed, and a plurality of beating chains (11) mounted to the rotating shaft in a radial and multistage manner so that a centrifugal force produced by high speed rotation of the rotating shaft causes the respective multistage beating chain groups to revolve at high speed to define multistage beating zones. Mounted to an inner wall surface of a peripheral wall portion (4) of the crusher vessel are a number of guide plates (15) having upwardly inclined surfaces in a direction of revolution of the beating chains for returning a substance being crushed to the beating zones from locations, in which the substance being crushed is scattered towared the inner wall surface. Furthermore, the beating chains are monted to the rotating shaft to be staggered in mounting intervals so that each beating chain is positioned in a middle position between adjacent beating chains in a subsequent stage. In addition, the respective beating chains are mounted on the rotating shaft such that they are connected to separate support bars (13) separately provided correspondingly to the respective beating chains and the separate support bars are fitted into support fittings (14) secured to the outer periphery of the rotating shaft with play gaps therebetween, in which gaps the respective beating chains can slide. Also, provided at the lowermost portion of the crusher vessel is a rotary disc (16) which is adapted to rotate about an axis, and on which scraping vanes (17) are provided to enable downward guiding and discharging of a crushed substance to the outside of the peripheral wall portion.
