Comprehensive utilization device for tailings

The invention discloses a comprehensive utilization device for tailings, and relates to the technical field of recycling of tailings. The device comprises a spiral conveyor, wherein the outer wall of the spiral conveyor is connected with a screening disc and a receiving disc located below the screening disc; the material screening disc is of an umbrella-shaped structure and is divided into a plurality of screening areas from the spiral conveyor to the outer side, and screening holes of different screening areas are different in size. The material receiving disc comprises a plurality of annular bearing grooves, the annular bearing grooves correspond to the screening areas in position, and one annular bearing groove is located in the outer edge of the material screening disc and used for bearing tailings falling off from the material screening disc. Discharging openings are formed in the bottom walls of the multiple annular receiving grooves correspondingly and used for discharging and collecting the received t
