The present invention relates to an automatic sorting device for aggregates, by selecting waste stones or mining stones by an automatic sorting device provided in a water tank to maximize utilization and reduce air pollution by minimizing dust generation according to sorting. It is to do. The present invention for realizing this, the input conveyor for introducing the waste aggregate； A housing in which the waste aggregate is input and seated, and a sorting plate for guiding and screening the waste aggregate are provided inside the housing, and the specific gravity of the waste aggregate is separated by a pressure by spraying water by spraying water on the side of the housing. A separator provided with a first pump and a second pump, and provided at the bottom of the housing with a third pump for raising a small specific gravity among the submerged waste aggregates； One side is submerged in the water tank is installed adjacent to the lower discharge portion of the sorter, the other end is installed outside of the water tank aggregate transport conveyor for discharging the aggregate has been completed to the outside； The bottom surface of the dewatering plate is made in the form of a mesh net so that the water is discharged downward, and the lower part is supported by a dust-proof spring, and the upper part is installed in conjunction with a vibrator, so that the water remaining in the foreign material is vibrated while the dewatering plate is vibrated by operation of the vibrator A dehydration part to be removed； It is characterized in that it comprises a； provided on the side of the dewatering unit to sequentially transfer the dehydration completed foreign matter.본 발명은 골재 자동 선별장치에 관한 것으로서, 폐석재, 또는 채광 석재를 수조내에 구비된 자동 선별장치에 의하여 선별하여 활용성을 극대화 시킴과 아울러 선별에 따른 먼지 발생을 최소화 시킴으로서 대기오염을 줄일 수 있도록 하기 위한 것이다.이를 실현하기 위한 본 발명은, 폐 골재를 투입하는 투입 컨베이어와； 폐 골재가 투입 안착되는 함체와, 상기 함체의 내부에는 폐 골재를 안내 선별 하는 선별판이 구비되고, 상기 함체의 측면에는 물을 분사하여 분사하는 압력에 의해 폐 골재중 비중이 큰 것과 작은 것을 분리하는 제1펌프 및 제2펌프가 구비되
