ABSTRACT:
A magnetic separation apparatus for separating metallic material from a granulated stream of mixed metallic and nonmetallic material comprises a vibratory conveyor having a trough assembly mounted on a suspension system and coupled to a motor for causing the suspension system to vibrate. The trough assembly includes an upper trough having at least two sections aligned in a predetermined direction of material flow and a lower trough extending in the same direction as and beneath the upper. The upper trough includes one or more gaps of a predetermined width so as to permit material to fall onto the lower trough. Each trough is arranged so as to feed a different output collection point. At least one of the gaps between a downstream section of the upper trough and an upstream section of the upper trough includes the downstream section positioned at a height lower than the upstream section thereby forming a vertical drop between the two sections with the gap positioned therebetween. For each gap, an adjustable gate may be used for adjusting the width of the gap. A magnetic separator may be arranged above the gap in the upper trough so as to pick up free metal. Rubber granules fall through the gap and are deposited in a receptacle, while metal is deposited on the upper trough which feeds a separate receptacle. A declumping zone comprising at least one perforated deck may be situated in-line with the upper and lower troughs.
