Born in magnetic separation process, the weight of magnetic separator magnetic system and the magnetic pole pitch lines related to polar distance smaller, more light weight magnetic system. Because of this reason, it seems that a small pole pitch magnetic separator magnetic system is reasonable. However, a very small distance, away from the magnetic pole surface of the magnetic field strength decreases too fast, and when the selected sub-chunks of ore, the ore will be a part of the magnetic field strength is too low in a region, the ore will be lost to the non-magnetic product to. In the magnetic field strength of the same machine a few faces and very different from the magnetic system, in which a small pole pitch magnetic system, in a very close to the surface and away from the pole faces where the magnetic field strength are great, but a little farther away from the pole surface, the magnetic field strength will drop a lot, that the depth of the smaller magnetic force.
