ABSTRACT:
Apparatus for automatically and selectively separating the components of an admixture of shredded materials in a scrap metal reclamation process according to the individual weights of such components. The apparatus includes conveying means for transmitting a shredded admixture of metals of various densities, lint, rubber, etc., to the periphery of a rotating drum. The periphery of the rotating drum is substantially completely perforate and is exposed from the interior thereof to a source of subatmospheric pressure. The rotating drum and a relatively fixed low pressure source interior thereof are so arranged that the differential between ambient pressure and the pressure at the drum perforations decreases as the drum rotates from a first point of material acquisition to a second point of deposition. This arrangement causes particulate components of the admixture to first become adherent to the perforations of the drum and then to drop free thereof, progressively, in accordance with the weight of each component, as the drum rotates. Additional conveying means are provided for collecting the various weight segregations of shredded materials, as they fall from the drum, for conveyance to different points of utilization.
