Abstract

Abstract Apparatus and method for economically separating reusable paper, cardboard, rags, metal, glass and the like from mixed household refuse is described. A separation station, preferably at a refuse transfer point, has a plurality of feed conveyors for moving mixed refuse past a plurality of work stations where valuable components of the mixed refuse are removed. These components are placed in receiving hoppers which communicate by chutes with a matrix of conveyor belts below the floor level of the work stations. Each work station has a plurality of such hoppers, each for receiving a particular component such as, for one example, cardboard, and the several cardboard hoppers feed onto ''''cardboard'''' conveyors for continuously moving the cardboard to a baling station or the like. Separate conveyors carry other components, such as metal, glass, paper or the like to separate processing stations. Some of the conveyors, preferably those handling large volume, run transverse to the feed conveyors and in opposite directions for carrying the bulkiest products to separate locations. Other conveyors at different elevations from the transverse conveyors run parallel to the feed conveyors for moving other products. Thus, each feed belt has a plurality of work stations, and each work station has a plurality of productreceiving hoppers. Each product-receiving conveyor serves a plurality of product-receiving hoppers of the same kind. Thus a large volume of refuse can be sorted rapidly and economically with most of the material handling being done automatically.
