CLASSIFIER FOR RECOVERING AGGREGATE

Japanese Patent JP3662356

B2

PROBLEM TO BE SOLVED: To simplify a structure, to reduce moisture contained in recovered gravel and to increase the flexibility of the discharge head of gravel in an aggregate recovery classifier separating aggregate in ready-mixed concrete according to diameter difference.
SOLUTION: A raw material charging pipe 43 is inserted in a separation drum 31 and the raw material supplied from the raw material charging pipe 43 is transferred to the other end of the separation drum 31 by an inner feed blades 44 and solids of gravel, send or the like in the raw material are separated and sedimented according to diameter difference by a separation hole 34 and the sediments stored in a sedimentation tank 33 are scraped up by an outward feed blade 32 and the scraped up sediments are discharged to the outside of the sedimentation tank 33 by a scooping-up discharge part 35 to recover aggregate. In the aggregate recovery classifier thus constituted, the separation drum 31 has a cylindrical shape opened at both ends thereof and the center line O thereof is arranged so as to be inclined by a predetermined angle θ with respect to a horizontal line H and the separation drum 31 is immersed in the surface of water of the sedimentation tank 31 on the side in which the raw material charging pipe 43 is inserted and the discharge side of large diameter matter of the separation drum 31 is exposed to the outside of water in the sedimentation tank 31 and formed into a blind cylindrical part 31A over predetermined length.
