Claim 10:
11. The device according to claim 1, further comprising a magnetic attaching drum configured to have circular type first and second side plates located on both sides thereof, sorting films surrounding a space between the first and second side plates, a magnetic force sorter mounted therein to provide a magnetic force, and the magnetic attaching drum sorting iron foreign substances by the magnetic force,
wherein the screening drum is located spaced apart from the magnetic attaching drum by a predetermined distance to allow first side plate of the screening drum to face the first side plate of the magnetic attaching drum, and the rotary shaft is coupled to the centers of the first side plates of the screening drum and the magnetic attaching drum and rotates with the power received from outside, the magnetic force generated from the magnetic force sorter of the magnetic attaching drum is applied to the iron foreign substances transferred along the conveyor belt from the sorting films, and the iron foreign substances are transferred in a rotating direction of the magnetic attaching drum in a state of being attached to the sorting films and discharged in a section where the magnetic force is not provided, thereby sorting the iron foreign substances and the lightweight foreign substances contained in the aggregates transferred along the conveyor belt in one direction sequentially.
