The present invention relates to a device for sorting and dehydrating sand for an aggregate. The device comprises: a vacuum screen which sorts a mixture including water and sand; a transferring unit which has an inlet and an outlet, receives the mixture sorted from the vacuum screen to be fed though the inlet, and separates the sand included in the mixture into first particles and second particles, which have the same or relatively smaller particle diameters than the first particles, in order to be discharged through the outlet; a dehydrating screen in which the first particles separated from the transferring unit are fed; a storing tank in which the second particles separated from the transferring unit are fed and which is disposed at the bottom of the dehydrating screen; and a separating unit in which the second particles stored in the storing tank are fed and which collects the mixture excluding fine sludge included in the second particles through a dehydrating screen. Accordingly, the collection rate of sand from raw ingredients is improved, and the fine sludge, which is waste, is minimally discharged so that the device of the present invention is environmentally friendly. |
