DEVICE FOR MAGNETIC SEPARATION OF FINELY DISPERSED RAW MATERIAL Russian patent published in 2007 - IPC B03C1/24 

FIELD: separation of strongly magnetic, paramagnetic and diamagnetic admixtures from any inert finely dispersed medium; concentration of minerals in processing dump in mining industry; extraction of magnetic, paramagnetic and diamagnetic admixtures in food-processing industry.

SUBSTANCE: proposed device may be used for separation admixtures possessing different magnetic properties from inert medium. Proposed device has taper vibrating feeder, separation chamber, revolving magnetic system made in form of hollow vertically oriented dielectric cylinder with permanent magnet units located radially along its axis. Separation chamber is made in form of hollow perforated cylinder located coaxially inside magnetic system; this cylinder is made from dielectric material and is provided with holes, 2-3 mm in diameter which are located in area of action of magnetic system. Fins wound spirally around perforated cylinder of separation chamber in way of holes; these fins are also made from dielectric material and their width is lesser than distance between inner perforated cylinder and magnetic system by 1-2 mm.

EFFECT: enhanced efficiency; possibility of separating mixtures into phases.
