Abstract:
1. A particulate material dedusting apparatus for cleaning unwanted debris from the particulate material, comprising: a housing; a central infeed opening directing a flow of contaminated particulate material into the housing; a pair of primary wash decks joined at an apex and extending downwardly and outwardly therefrom to opposing discharge edges, said apex being positioned beneath said central infeed opening to divide said flow of contaminated particulate material between said primary wash decks; a Venturi zone located outboard of each respective discharge edge; a discharge port supported by said housing below each respective Venturi zone so that both said discharge ports provide for a simultaneous discharge of the same particulate material as received through said central infeed opening; a support leg supporting said discharge edge of said at least one wash deck at a position spaced above said discharge port, said support leg including louvers formed therein; and an air flow manifold directing a flow of air through openings in said primary wash decks and through said louvers in said support leg and below said discharge edges of said wash decks to provide a flow of air into the respective Venturi zones.
