PROBLEM TO BE SOLVED: To separate surely highly precisely a magnetic substance from a nonmagnetic substance by a method wherein on an inner wall of an apparatus wherein a high speed draft from a turbofan collides against, a broken piece in which a magnetic substance and a nonmagnetic substance are entangled is separated, and the magnetic substance is attracted by magnet rollers arranged in upper and lower two stages. SOLUTION: A broken piece wherein a magnetic substance broken piece 7 and a nonmagnetic substance broken piece 8 are entangled, collides against an apparatus inner wall part 6b by a high speed draft from a turbofan 1 and after being separated by its impact, it reaches a magnet roller 2. Then, in the magnet roller 2, the broken pieces are attracted onto an outside cylindrical part surface at positions A, B. Then, when a broken piece comes to a position C, it drops by being released from the attraction force. In the case where it reaches a surface of a magnet roller 3 in dropping, the magnetic substance comes in contact with the outside cylindrical part, comes to a reverse relational position to that in the case where it comes in contact with the magnet roller 2, only the magnetic substance is attracted, the nonmagnetic substance made in a free condition is housed in a nonmagnetic substance container 6, and the magnetic substance is housed in a magnetic substance container 4. |
