PURPOSE:To fractionate correctly magnetic components without damaging them from a mixture of magnetic components and dummies of non-magnetic or feeble-magnetic components. CONSTITUTION:A mixture of magnetic components A and dummies B of non- magnetic or feeble-magnetic is transported on a conveyer 1. A belt 11 is circulated between the first roller 3 and the second roller 10, and the first roller 3 equipped with a magnet 4 is arranged so that the peripheral surface of the roller 3 closely faces the transport surface 2 of the conveyer 1. By the magnetic force acting from the magnet 4 in the roller 3 through the belt 11, the magnetic A on the conveyer 1 adhere on the peripheral surface of the roller 3 to be transferred to its upper side. Additionally, when the belt 11 separates from the first roller 3, the magnetic A, which are held on the belt 11, are enforced to separate from the magnetic force of the magnet 4 in the roller 3 to drop into a chute 7 on the side of the second roller 10, and are discharged. On the other hand, the dummies B are discharged through a chute 14 placed at the tip of the first roller 3. |
