ル表面の磁気勾配を利用したものであった。(b) Conventional technology Dry magnetic separators include those in which the processed material is passed through a narrow gap between two excited rotating rolls, and ferromagnetic materials are absorbed and removed by the rolls, and those in which the ferromagnetic material is removed from the surface of a single induction magnetic roll. There is a type that adsorbs and removes ferromagnetic powder. Both were electromagnetic, with the former utilizing a high magnetic field in the air gap, and the latter utilizing the magnetic gradient on the roll surface.

小さいなどの問題があった。(c) Problems to be solved by the present invention However, since it is an electromagnetic type, not only does it consume a lot of power, but it also causes electrical troubles because the electromagnetic coil is placed in the flow of the processed material. There were problems such as a large amount of gas, an inability to form a sealed structure, and a small throughput due to the flow of the processed material through a narrow gap.

状態となる。The ferromagnetic matrix 5, which has now entered between the inner magnetic pole 1 and the outer magnetic pole 2 as the drum rotates, immediately reaches a magnetic saturation value (15,000 to 20,000 Gauss) due to magnetic induction. The moment it exits between the internal magnetic pole 1 and the external magnetic pole 2, it becomes demagnetized.

00 to 4000 gauss, which can be sufficiently obtained with a permanent magnet, so there is no need to use an electromagnet, and if the chute at the bottom of the frame tank is connected to the next process, it will be a sealed structure, which solves various problems with dry magnetic separators. It became possible to dispel them all at once.
