MAGNETIC SEPARATOR Russian patent published in 2008 - IPC B03C1/10 

FIELD: mining industry; other industries; production of the magnetic separator used for separation of the material according to their magnetic properties.

SUBSTANCE: invention is pertaining to separation of the material according to their magnetic properties and may be used at reprocessing of the magnetite ores. Invention allows to improve efficiency of crushing of magnetic conglomerates at the expense of action of the magnetic forces with the variable value of the radial component and the inversion tangential component during movement of the separated product by the gyrating drum concerning the magnet system. The separator includes: the non-magnetic drum mounted with the capability of rotation; the bath; the loading and unloading tools; the magnet system located inside the drum and made in the form of the mounted on the magnetic conductor the main permanent magnets of the rectangular shape and the fixed on the surface the magnets and additional magnets made in the form of rectangular prisms and fixed on the surface of the main permanent magnets. Main and additional magnets have similar magnetic polarity. Prisms of additional magnets have smaller width, than main permanent magnets and, and are mounted in radial direction with clearance between them.

EFFECT: invention ensures increased efficiency of crushing of magnetic conglomerates.
