according to the magnetic source‚ the magnetic separator can be divided to permanent magnetic separator and electromagnetic separator. 2‚ according to the strength of magnetic field‚ it can be divided into: (1) Weak magnetic separator‚ the surface magnetic strength HO=72-136 KA/m‚ magnetic force HgradH= (2.5-5.0) 1011 A/m. (2) Middle magnetic separator‚ the surface magnetic strength HO=160-480 KA/m; (3) Strong magnetic separator‚ the surface magnetic strength HO=480-1600 KA/m‚ magnetic force HgradH=
