Abstract: The method and apparatus for separating materials includes a feed splitting assembly (27) which evenly divides the materials to be separated into equal parts for inputs to a like plurality of screen assemblies (16, 17, 18). These inputs are evenly distributed across the width of some of the screen assemblies (17, 18) by manifolds (44, 51). One of the screen assemblies (16) can receive the input directly through an aperture (40) in the feed splitting assembly (27). The material not passing through the screen assemblies (16, 17, 18) is collected at one location and the material passing therethrough is transmitted to a common discharge spout (55).
Abstract: A material separating device includes a support member (21) carrying one end of a plurality of rod members (18, 19). The rod members (18, 19) are mounted in a staggered relationship defining two rows which together form separating decks (16, 17). Each rod itself consists of a metallic core (22) and plastic sheath member (25). The diameter of the sheath member (25) determines the distance between adjacent rod members (18, 19).
Abstract: A material separating device (10) includes a frame member (13) which carries a plurality of vertically arranged support members (19-23). Each of the support members (19-23) includes a plurality of support rods (19A-D, 20A-D, 21A-D, 22A-D, 23A-D). Screen elements (24-28) are stretched by adjustable tensioning devices (30) over each of the support members (19-23) to form screen panels (24a-e, 25a-e, 26a-e, 27a-e, 28a-e) between the support rods (19A-D, 20A-D, 21A-D, 22A-D, 23A-D). Each successive screen panel (24a-e, 25a-e, 26a-e, 27a-e, 28a-e) is inclined at a greater angle than the preceding screen panel (24a-e, 25a-e, 26a-e, 27a-e, 28a-e) so that material being separated moves progressively faster as it traverses each screen element (24-28).
Abstract: Apparatus for separating a composite of three materials into their particular groups includes a first screen (17) which permits the group of the smallest sized material to pass therethrough. The materials not passing through the screen (17) are fed to a trough (21). Second screens (23) are provided near the end of the trough which permits the group of the mid-sized materials to pass therethrough. The group of the largest sized materials move to and through a discharge spout (25) at the end of the trough (21).
