Provided in a casing (31) are a rotating shaft (32), a cylindrical-shaped wire body (33) which coaxially surrounds the rotating shaft (32) and rotates in an opposite direction to that of the rotating shaft (32), a screw shaft (34) disposed below the cylindrical-shaped wire body (33), an arcuate-shaped wire body (35) provided below the screw shaft (34) to extend in a sliding contact wit the screw shaft (34), and a lower screw shaft (36) provided below the arcuate-shaped wire body (35). A suction pipe for sucking an atmosphere in the casing (31) is connected to an upper portion of the casing (31), and a plurality of agitating rods (32a) are provided on a surface of the rotating shaft (32). The casing (31) is provided with a defective goods loading port, a first separate substance discharge port for discharging a first separate substance therethrough, a second separate substance discharge port for discharging a second separate substance remaining on the arcuate-shaped wire body (35) therethrough, and a final separate substance discharge port for discharging a final separate substance conveyed by the lower screw shaft (36) therethrough. Dans un carter (31), il y a un arbre rotatif (32), un corps cylindrique (33) en fil métallique qui entoure l'arbre rotatif (32) en étant coaxial avec lui et qui tourne dans une direction opposée à celle de l'arbre rotatif (32), une vis sans fin (34) située en dessous du corps cylindrique (33) en fil métallique, un corps de forme courbe (35) en fil métallique disposé sous la vis sans fin (34) pour venir en contact coulissant avec la vis sans fin (34) et une vis sans fin inférieure (36) disposée en dessous du corps de forme courbe (35) en fil métallique. Une conduite d'aspiration pour aspirer une atmosphère dans le carter (31) communique avec une portion supérieure du carter (31) et plusieurs tiges d'agitation (32a) sont prévues sur la surface de l'arbre rotatif (32). Le carter (31) comporte une ouverture pour introduire les déchets, une première sortie pour évacuer un premier type de substances séparées, une seconde sortie pour évacuer un second type de substances séparées restant sur le corps de forme courbe (35) en fil métallique et une dernière sortie pour évacuer un autre type encore de substances transportées par la vis sans fin inférieure (36).
