<p>A mobile frame has a primary rotary brush in contact with the ground and with secondary brush parallel to an behind the primary brush. The brushes pick up materials from the ground and toss them against a reflecting panel and onto a primary conveyor belt leading rearwardly. A stream of air is impelled to flow along the primary conveyor and assists in lifting lighter waste materials therefrom. An upwardly traveling draft of air, flows through a separator column and produces a further separation of the lighter, irregularly shaped materials from the heavier, uniformly shaped materials.</p> |
