ABSTRACT:
A method and apparatus for separating aluminum-based materials from non-aluminum materials is provided. The apparatus includes a conveyor which leads into a chute. Mixed materials which may be pre-shredded travel along the conveyor and into the chute. An adjustable air header assembly is provided at the end of the conveyor within the chute which directs an air stream generally upwardly and at an angle towards the end of the conveyor and the pieces of material thereon. A predetermined air velocity and air flow is selected such that the lighter aluminum materials are lifted and blown, or propelled, a fixed distance as they emerge from the end of the conveyor and the heavier non-aluminum materials fall short of that distance. Suitable collection bins are provided at the appropriate location. The apparatus and associated method used are particularly suited to separating used food and beverage can stock before it enters a recycling station.
