AbstractA vibratory particle separation apparatus of the type having at least two plateau conveying surface interrupted by a drop-out opening. A composite mixture is conveyed by a vibrating action beyond the upper plateau and over a foraminous section in the upper plateau adjacent the drop-out opening. Air is directed upwardly through the foraminous section to break apart the composite mixture, and an air supply is also directed angularly in relationship to the plane of the upper 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 level. In another aspect of the invention, the landing area is adjustable angularly with respect to the plane of the upper plateau of the conveying surface and is translatable to constrict or enlarge the dimensions of the drop-out opening. The particles passing through the drop-out opening and not intercepted by the landing area exit the system.
