ABSTRACT:
A vibrating dual deck dewatering unit which includes a lower screen deck and an upper screen deck. Material being processed by the unit is discharged from the upper screen deck onto the lower screen deck in such a manner that excess water is allowed to backflow beneath the upper screen deck, while solids are directed in an opposite direction. The upper screen deck is provided with a jagged discharge lip which creates interruptions or gaps in the flow of discharged solids. The excess water which is discharged from the upper screen deck is allowed to backflow through the interruptions or gaps in the discharged solids that are created by the jagged discharge lip of the upper screen deck.
