[0002] A vibrating screen is one of the most common machines in the mineral industry, usually used in the operation of mineral screening. Its principle is to pass alternating current through a coil wound around an iron core to generate a magnetic field, and this magnetic field will interact with a permanent magnet at the bottom of the vibrating screen to generate excitation. This high-frequency excitation acts on the vibrating screen and screens the ore above the vibrating screen. This method of mineral screening is relatively convenient and the mechanical structure is simple. It is one of the most commonly used in current mine vibrating screens.

[0003] A high-frequency electromagnetic vibrating screen is a device that uses the principles of high-frequency vibration and electromagnetic induction to screen materials. In order to achieve high-precision and high-speed screening of materials, therefore, a high-frequency electromagnetic vibrating screen is required to screen materials. Most of the existing high-frequency electromagnetic vibrating screens generate a magnetic field by using current and generate vibration through the interaction between magnetic fields. However, the magnitude of the current is fixed, which will cause the larger the mass of the material on the surface of the vibrating screen, the smaller its vibration amplitude, thus affecting the efficiency of material screening. Moreover, the existing high-frequency electromagnetic vibrating screens are not convenient for cleaning the materials attached to the screen plate, and will cause blockage of the screen plate after long-term use, thus reducing the efficiency of material screening.
