Abstract
A vibratory screening apparatus for dry, very fine material. A vibratory housing is employed with parallel screening elements disposed across the housing and spaced vertically. The lower screening element has a much finer mesh size than the upper screening element. The housing includes an opening laterally from between the two screening elements for discharge of material not passing through the lower screen. Sliders are positioned between the screens which have a flat lower surface for riding directly on the lower screen and extend a major portion of the distance between the upper and lower screens.
