The existing magnetic separator has a magnetic field all the time, a certain amount of magnetic force exists on particles, and agglomeration phenomenon among the particles is serious due to the magnetic force, so that magnetic agglomerates are formed. Compared with the existing magnetic separator, the magnetic separator needs to perform demagnetizing treatment on the particles after magnetic separation, and a special demagnetizer needs to be installed.

The monitoring camera 63 sends the shot image to the controller, and through image analysis, the remaining amount stacking height of the particles is obtained, and the magnetic flux of the magnetic separation unit 411 is adjusted accordingly. Specifically, if the accumulation amount of the remaining particles is large, the current of the circuit inside the magnetic separation unit 411 is increased, the magnetic flux is increased, more particles are magnetically adsorbed, and the situation that the particles are excessively accumulated to block the magnetic separation groove 44 is avoided; on the contrary, the accumulation amount of the residual particles is small, the current of the circuit inside the magnetic separation unit 411 can be reduced, the magnetic flux is reduced, and the adsorption amount of the particles is reduced, so that the particle amount in the magnetic separation groove 44 is in a suitable and stable range, the energy consumption of the magnetic separator is reduced, and the economical efficiency of the whole magnetic separation system is improved.
