MAGNETIC SEPARATOR Russian patent published in 2012 - IPC B03C1/10 

FIELD: instrument making.

SUBSTANCE: invention relates to magnetic separation, particularly, to devices for extraction of magneto-susceptible particles from fluids, and may be used in mining, metallurgy, etc. Magnetic separator comprises case to house nonmagnetic drum and magnetic system rigidly coupled with separator base, loading and discharging devices. Magnetic system is made up of permanent magnets with alternating polarity and magnetic field intensity amplitude increasing in drum rotational direction in separator first working zone. In its second zone, permanent magnets feature equal amplitude of magnetic field intensity exceeding that in first zone at preset spacing of poles on both zones. In third zone, permanent magnet is arranged to have magnetic field intensity amplitude that ensures retaining magnetite above zone of discharging separator tails. Note here that separator fourth zone accommodates permanent magnets with intensity amplitudes and spacing of poles smaller than those in second zone. Note also that ferromagnetic rods are built in the drum.

EFFECT: higher quality of concentrate.
