Abstract
A dewatering device for aggregate products such as sand and gravel to allow dewatering to a moisture within the range of 8% by weight. This energy efficient dewatering system uses an inclined rotatably mounted dewatering screw to initially dewater, followed by an associated vibratory dewatering screen to achieve combined results that neither an inclined dewatering screw or a vibratory screen can achieve separately.
