PROBLEM TO BE SOLVED: To surely sort aluminum alloy cans and plastic containers by arranging a driving roller on one end side of an endless belt and arranging a magnetic material drum and magnetic drum engaging with this endless belt at its other end, thereby utilizing the action of managnetic field. SOLUTION: The drive roller 15 and a motor 16 driving this roller are arranged at one end side of the endless belt 11. The other end is provided with the magnetic material drum 13 which engages with the endless belt 11 and is rotationally driven by the same and the magnetic drum 12 having plural coils 12 independently from the magnetic material drum 13 on the inner side thereof. Magnetic force is generated in the magnetic drum 12 and the magnetic material drum 13 by rotationally driving the magnetic drum 12. As a result, the steel cans 93 are attracted by the magnetic material drum 13 and the aluminum alloy cans 91 are thrown to a place remote from the other end provided with the magnetic material drum 13, etc., by the action of the magnetic force of the coils 121 by which the aluminum alloy cans are classified from non-metallic containers 92. |
