ABSTRACT:
A vibratory material separating apparatus has at least two plateau conveying surfaces interrupted by a drop out opening. A composite mixture is conveyed by a vibrating action beyond the first conveying plateau and over a foraminous section in the first conveying plateau adjacent the drop out opening. Air is directed upwardly through the foraminous section to break apart the composite mixture, and an air supply formed by an air duct is also directed angularly in relationship to the plane of the first conveying plateau to further break apart the composite mixture and to propel particles of predetermined density and/or dimension to the landing area on the second conveying plateau. The air duct is adjustable between a first position and a second position to form an air stream having an adjustable and width. In another aspect, a separating tube is located between and spaced from the first and second conveying plateaus, within the drop out opening. The separating tube interacts with the air stream produced by the air duct to assist in carrying particles passing over the leading edge of the separating tube over the drop out opening and onto the landing area of the second conveying plateau.
