The utility model discloses a device for separating light articles from construction waste. The device comprises a shell, a material feeding belt, an aggregate transfer belt, an aggregate discharging belt, a light article belt A, a light article belt B, a negative pressure belt, a primary air separation draught fan, a secondary air separation draught fan and a separation rotating drum, wherein the material feeding belt, the aggregate transfer belt, the aggregate discharging belt, the light article belt A, the light article belt B, the negative pressure belt, the primary air separation draught fan, the secondary air separation draught fan and the separation rotating drum are arranged at the inner part of the shell. According to the device disclosed by the utility model, air blowing, negative pressure and the separation rotating drum are utilized, and the separation of aggregate and the light articles of the construction waste is realized by mainly utilizing an elasticity separation principle by the separation rotating drum; the light articles can be cleared after the elasticity separation and the negative pressure separation of the separation rotating drum are carried out, ferrous metal can be also cleared by additionally arranging an iron removing device, the purity of the aggregate is fully ensured, the national standard can be completely met by produced recycled aggregate, and the later secondary utilization can be convenient; the device can be also used for the separation of other two articles in different specific gravities.
