Recycled aggregate separation device for construction waste

The invention discloses a construction waste recycled aggregate separation device which comprises a first system, the first system is communicated with a second system, the second system is communicated with a separation system.According to the construction waste recycled aggregate separation device, crushed non-magnetic substances are conveyed into a third roller through a second conveying belt, and the third roller is communicated with a second conveying belt; the first roller is adjusted to rotate, the first roller drives the second roller and the third roller to rotate, crushed nonmagnetic substances are screened through second screening holes in the third roller firstly, fine aggregate and micro powder pass through the second screening holes, the fine aggregate and the micro powder enter the inner wall of the second roller, and the micro powder enters the inner wall of the first roller after being screened through the first screening holes; and the first roller, the second roller and the third roller are
