摘要

PURPOSE: A device is provided for separating and washing aggregate from construction waste article by more effectively separating float wastes from the aggregate. CONSTITUTION: The apparatus includes a reservoir(1) for storing a constant amount of water therein and having an outlet at a rear portion thereof. Two screw-type of rotary members(10) concentrically disposed are installed along a longitudinal direction of the reservoir.
