PURPOSE:To provide a magnetic meneral dressing device which gradually attenuates the magnetic force of magnetic poles from the supply side of raw material to be dressed to the discharge side to increase the process amount with economical magnetic poles. CONSTITUTION:Raw materials are dispersed and floated by the stirring action of AD magnetic field produced by AD magnetic poles 5, 11. Most part of non-magnetic particles are dropped as they are by gravity and discharged to the outside through a non-magnetic particle transporting chute 16 provided on the lower portion. The magnetic particle group including non-magnetic particles are dressed while skipping alternatively over magnetic pole rows 6, 12 opposed to each other and discharged to the outside through magnetic particle transporting chutes 17a, 17b. Such group repeats positively the skipping and dressing even if a great amount of raw materials are supplied since the magnetic force of magnetic pole is greater at the supply side so that the magnetic pole is greater at the supply side so that the magnetic force corresponding to the passing amount of raw material acts thereto. |
