A water tank-type aggregate sorting device having a drum screen is provided to reduce an installation area by making a screen-type drum in a double structure and to reuse the water for removing foreign materials, by purifying the water through a precipitation tank. In the water tank-type aggregate sorting device(10) having a drum screen(20), the drum screen has inner and outer cylinders(30,40) made of a perforated net and integrated with each other, and sorts out aggregates poured through an input port(36) formed at one side, through the perforated net formed along the outer peripheral surface according to the size with transferring the aggregates to the other side. A housing(50) rotatably supports both ends of the drum screen to dip the aggregates in the water, and comprises a transfer screw(51) installed at the inner bottom in an axial direction to deliver the sorted aggregates toward one side and a collecting tank(52) formed at one end to collect the delivered aggregates. First, second, and third conveyors(71,72,73) receive the aggregates sorted and loaded through the inner and outer cylinders of the drum screen and the housing, through a delivery unit and then transfer the received aggregates. |
