Background
It is known from the law of electromagnetic induction that a conductor generates an induced current in a changing magnetic field, and the biot-savart law shows that the magnetic field exerts a force on a current-carrying conductor or coil. In an alternating magnetic field, the metal conductor can be excited to generate eddy current, the magnetic field generated by the eddy current and an external magnetic field interact to enable the metal conductor to be acted by the eddy current, and the nonconductor cannot generate the influence. By using the principle, equipment for separating the conductor from the nonconductor can be designed, namely an eddy current separator, also called an eddy current separation device. In the eddy current separation process, the material separation mode is direct, secondary waste is not generated, and the method has high application value.

Therefore, the distance between the material and the magnet should be reduced as much as possible to strengthen the effect of eddy current force, however, in the prior art, the eddy current magnetic roller is positioned inside one of the conveyor rotating wheels, the conveyor rotating wheel and the material conveying belt are used for realizing effective conveying of the material through self action, therefore, the conveyor rotating wheel and the material conveying belt need to have certain strength (namely, the conveyor rotating wheel and the material conveying belt need to have certain thickness), the conveyor rotating wheel and the material conveying belt have certain thickness, in addition, in order to ensure the stable operation of the equipment, a certain gap needs to be left between the eddy current magnetic roller and the conveyor rotating wheel, finally, the sorted material on the material conveying belt has a larger gap from the eddy current magnetic roller, and the gradient of the magnetic field actually influencing the material is lower during sorting, that is, the belt type eddy current separator is only suitable for separating coarse-grained (centimeter-level) materials due to the fact that engen cannot separate fine-grained (millimeter-level) materials.
However, in the actual process of recycling solid wastes, the problem of separating fine metal materials is always faced, even if the coarse metal materials are mixed with a plurality of fine metal materials, the current mainstream fine separation process is salt washing, shaking table, winnowing and other operations, but the related processes have the problems of secondary pollution, poor separation effect and the like.
