Classification magnetic separation device based on grade of iron tailings

The grading magnetic separation device based on the iron tailing grade comprises a rack, a feeding bin is fixed to the upper portion of the rack, a feeding port is formed in the left side of the feeding bin, the rack is provided with an electromagnet, the electromagnet is located below the feeding bin, the magnetic field direction of the electromagnet is the left-right direction, and the electromagnet is electrically connected with a control box. The control box is used for controlling the magnetic field intensity of the electromagnet; a discharging bin is arranged at the bottom of the machine frame, and a partition baffle is arranged in the discharging bin. Compared with the prior art, through the comprehensive force field application of the magnetic attraction force and the gravity, the separation efficiency can be improved, or blockage can be weakened, and therefore the purpose of efficient separation is achieved. By adjusting the magnetic field intensity and changing the magnetic attraction force, the iron tailings with different iron contents can be obtained, the iron tailings can be separated in a gradient mode according to grades so as to play the maximum effect, the size is small, the weight is light, the energy consumption is low, and energy is saved by 90% compared with a common magnetizer.
