1. A vibratory material separating apparatus comprising:

  • a conveying surface for moving a composite mixture in a conveying direction between an inlet end and a discharge end, the conveying surface having a first conveying plateau and a second conveying plateau spaced from the first conveying plateau toward the discharge end to form a drop out opening between the first and second conveying plateaus, the first conveying plateau directing the composite mixture substantially along a plane adjacent the drop out opening and having an edge at the drop out opening, the second conveying plateau having a landing area including at least a portion spaced beneath the edge of the first conveying plateau;

    a vibratory actuator for vibrating the conveying surface to effect vibrating movement of the composite mixture;

    a source of pressurized air including at least one pressure chamber and a blower communicating through the at least one pressure chamber; and

    a deflector plate for directing air from the pressurized air source through the drop out opening and angularly upward with respect to the plane of the first conveying plateau and from underneath the composite mixture moving over the first conveying plateau edge, the deflector plate cooperating with the pressure chamber to define an air duct, the deflector plate being shiftable between a first position, wherein the deflector plate is shifted towards the first conveying plateau so that the air duct has a first width, and a second position, wherein the deflector plate is shifted away from the first conveying plateau so that the air duct has a second width larger than the first width.
