The electrical components appearing in the text are all connected to the controller and the power supply. The control circuit of the controller can be implemented by simple programming by technicians in this field. The provision of power supply is also well known in the art, so the control method and circuit connection are no longer explained in detail in this utility model.

[0042] The working principle of the above embodiment is:

[0043] When in use, when the strength of the magnetic field in the inner cavity of the screening bin 1 needs to be adjusted, the two micromotors 77 drive the upper end shaft 76 to rotate, so that the shaft 76 can drive the upper end meshing gear 75 and the driving gear 78 to rotate, so that the upper end driving gear 78 can drive the lower end driving gear 78 to rotate through the two transmission gears 79 on the same side, so that the upper and lower driving gears 78 turn relative to or away from each other, so that the upper and lower two groups of driving gears 78 can drive the upper and lower meshing gears 75 to rotate relative to each other through the shaft 76, so that the two meshing gears 75 in the same group can mesh with the tooth plate 73, so that the two meshing gears in the same group can mesh with each other. The engaging gear 75 can drive the vertical plate 72 to move in the connecting bin 7 through the concave block 74, so that the left and right push rods 71 ​​can drive the distance between the two magnetic blocks 6 to gradually shorten, so as to adjust the strength of the magnetic field; the upper and lower sets of meshing gears 75 rotate in opposite directions, so that the two concave blocks 74 can drive the left and right push rods 71 ​​to move in opposite directions through the vertical plate 72, thereby adjusting the distance between the two magnetic blocks 6 to gradually extend, so as to adjust the strength of the magnetic field, thereby being able to magnetically separate iron ores with different magnetic strengths, which can effectively improve the magnetic separation effect and avoid affecting the recovery rate and quality of the iron ore;

[0044] When the iron ore enters the screening bin 1 through the feed hopper 2, the magnetic iron ore can be adsorbed on the magnetic separation roller 3, and the inclined block 4 can block the non-magnetic iron ore, allowing the non-magnetic iron ore to fall into the recovery bin 5 on the left, while the magnetic iron ore is pushed into the recovery bin 5 on the right by the inclined block 4, thus completing the magnetic separation process of the iron ore.
