    1523319 Magnetic separators MAGNESEP CORP 1 Dec 1975 [9 Dec 1974] 49202/75 Heading B2J A mixture of more and less magnetic materials is separated by feeding the mixture as a slurry into the inlet 45 of a mixing chamber 44 which receives through tube 43 a supply of soft iron spheres 39 which are interspersed with the slurry and fed down an inclined duct 33 having a portion formed by the pole faces of electromagnets 31, 32 which cause the more magnetic materials to adhere to the iron spheres 39 while the less magnetic materials are washed away by water from a pipe 49 and out of outlet 47 and 47' at a portion of the duct 33 which has a perforated floor, where as the more magnetic materials remain with the spheres 39 until they leave the magnetic field, whereupon they are demagnetised and are tumbled to remove the adherent material and returned by a conveyor 41 to the input of the apparatus. The movement of the material is assisted by a driven continuous chain 36 having projections 46. Fig. 7 (not shown) illustrates a modification wherein the spheres and materials are mixed at the lower end of the apparatus and are fed together up to the input of the apparatus.

    FIELD OF THE INVENTION The invention relates to the field of mineral processing.
    A poly gradient electromagnetic separator is known, including a working body made in the form of a drum, a magnetic system placed inside a drum, a polygradient medium placed on the outside of the drum, receivers of separation products 1.
    The disadvantage of this separator is the presence of magnetic scattering fluxes.
    Also known is a polygradient electromagnet separator, including a working body, a magnetic system with poles placed outside the working body, a polygradient medium placed inside the working body, devices for moving the polygradient medium in the separation zone and out of it, a device for regenerating the polygraphic medium feeding and discharge pipe 2.
    The disadvantage of this separator is the low efficiency of the separation process due to the presence of magnetic scattering fluxes.
    The aim of the invention is to increase the efficiency of the separation process by reducing the magnetic flux of the scattering.
    This goal is achieved by the fact that the working body of the separator is made in the form of a gutter, and the poles are installed flush with the walls of the gutter, the gutter is inclined to the horizontal, and the device for moving the poly gradient medium inside the gutter is made in the form of an endless chain with lugs.
    Fig, L shows the proposed separator, front view; in fig. 2 the same, the embodiment; in fig. 3 section A-A of FIG. one.
    The separator works as follows.
    The separator includes chute 1 mounted inclined to the horizontal on frame 2 with the ability to change the angle of inclination, electromagnetic system consisting of coil 3, mag5 nitpipe 4 and poles 5 installed flush with the walls of chute 1, poly gradient K) medium 6, device . for moving the media in the separation zone, made in the form of an endless chain 7 with protrusions 8 mounted on asterisks 9, a device for moving the polygraphic medium outside the separation zone, made in the form of a conveyor 10 or in the form of a pipeline 11 equipped with a pump 12, device 13 for regeneration of the polygradient medium, hopper 14, supply nozzle 15, mixing chamber 16, tray 17, nozzle 18 with valve 19 for discharging non-magnetic fraction, nozzle 20 for supplying wash water to trough 1, nozzle 21 for removing f rinse water in the blender 22, pipe 23 for unloading the magnetic fraction.
    The separator works as follows.
    The source material and polygraphic medium, made in the form of spherical bodies, are made from the mixing chamber 16 and from there enter the channel 1, the angle of which is adjustable to provide the necessary flow rate of the source material. The spherical bodies constituting the polygradient medium, in the area of the magnetic field, form a dense mass having pores and move along the groove by means of a device consisting of an endless chain 7 with protrusions 8 mounted on asterisks 9. The velocity of the polygradient medium is controlled by changes in the speed of movement of the infinite chain 7. Magnetic particles are retained on the elements of the polygradient medium, and non-magnetic particles are discharged through the pipe 18 with the valve 19. Through the pipe 20 into the groove 1 towards the flow n ligradientnoy medium supplied wash water to increase the quality of the magnetic fraction, the wash water is removed through conduit 21. Poligradientna media from trough 1 is supplied to a device 13 for regeneration, and then purified by magnetic particles - on the conveyor 10 which pefemeschaet it to the loading hopper
    x4, or through conduit 11 using pump 12, it moves to the mixing chamber 16. Magnetic particles are discharged through pipe 23, the working body is executed in de gutter, setting the poles flush with the walls of the gutter allows to create in the separation zone an electromagnetic field with high induction due to the elimination of gaps between the poles and the poly gradient medium and
     elimination of magnetic flux scattering, which contributes to the efficiency of the separation process.
