  • Method of and apparatus for electrodynamic separation of nonmagnetic free-flowing materials
    Patent number: 4238323
    Abstract: Electrodynamic separation of nonmagnetic free-flowing materials is accomplished by feeding the flow of a material into a region of maximum intensity of a variable nonuniform magnetic field for inducing maximum eddy currents in electrically conducting particles of the material being separated and producing maximum electromagnetic forces which deflect the electrically conducting particles from the direction of feed of the material being separated.The variable nonuniform magnetic field is generated by an electromagnet having a closed magnetic core with a magnetic air gap defined by pole pieces. The electromagnet pole pieces are symmetrically divergent from the pole axes in a plane substantially perpendicular to the direction of feed of the material being separated.
