Spin line passes through magnetizing mediums；So, sorting path of the ore particle in magnetizing mediums is very long, and the probability captured by magnetizing mediums is very big, can be with
Significantly improve the magnetic concentrate rate of recovery.
（3）Using interior ring type permanent magnetic system, magnetic pole magnetic alternately changes, and captures the magnetic ore particle hair in magnetizing mediums silk table face
Magnetisation rolling effect, further increase the selectivity of assorting room.
（4）By the rotating speed for adjusting magnetizing mediums, thus it is possible to vary centrifugal force size of the ore particle in magnetic field, to adapt to dissimilarity
The sorting of matter ore.
