[0002] Magnetic material is a material that can respond to external magnetic fields. There is permanent magnetism inside this material. The direction of the magnetic moment inside the unmagnetized material is randomly distributed. After being magnetized, the magnetic material can be used in many fields. However, there are many kinds of magnetic materials, and their different magnetic permeabilities make their reactions to magnetic fields different. Based on this characteristic, they can be screened out by controlling the size of the magnetic field. The magnetic material screening device in the prior art can only roughly screen the magnetic materials, and cannot clearly distinguish between multiple magnetic materials. At the same time, it is impossible to distinguish between temperature-sensitive and insensitive magnetic materials. Summary of the invention

[0009] The rotation of the side bevel gear drives the lower wheel to rotate through the docking bevel gear, and drives the upper wheel, horizontal shaft, worm and long shaft to rotate through the vertical transmission belt. The worm drives the worm wheel, vertical shaft and upper gear to rotate, thereby driving the grinding gear and feed hopper to rotate, and the magnetic material is put into the feed hopper. The magnetic material reaches between the grinding gear and the filter plate through the feed channel.

In this way, the materials are separated into the left discharge trough 312 and the right discharge trough 313 according to their temperature sensitivity. The farther away from the grinding frame 201, the greater the magnetic force of the electromagnet 311 of the fine separation device is set. The three fine separation devices are used to separate the magnetic materials into high, medium and low magnetic materials, and the high, medium and low magnetic materials are further divided into temperature sensitive and temperature insensitive materials, a total of six groups.
