ELECTROMAGNETIC GRAVITATIONAL SEPARATOR Russian patent published in 2014 - IPC B03C1/26 

FIELD: process engineering.

SUBSTANCE: invention relates to magnetic separation with free falling material. Electromagnetic gravitational separator comprises electromagnet with polar tips, control unit, bumper (1) fitted at product duct bottom (2), jacket-pan with handle (3) that covers polar tips. said electromagnet is equipped with magnetisation coils (4) fitted on cores (5) provided with polar tips. Control unit adjusts magnetic induction at concentrators. Inclined product duct (2) is arranged at 45-70° to horizontal line. Separator comprises the set of replaceable polar tips for removal of iron inclusions. Polar tips are composed of magnetic field concentrators with round and square holes.

EFFECT: higher inhomogeneity of magnetic field, decreased number of winding turns, higher magnetic induction at concentrators.
