    1501396 Magnetic separation ENGLISH CLAYS LOVERING POCHIN & CO Ltd 17 July 1975 [19 July 1974] 32216/74 Heading B2J A separating chamber in a magnetic separator has an inlet 1 and an outlet 2 for a fluid containing magnetisable particles, and between them a mass 4 of paramagnetic material which is pervious to the fluid, a mass of material being defined by a statement that the fluid spends a large proportion of its time in the chamber actually passing through the mass. A first embodiment, Fig. 1 shows apparatus for separating out ferromagnetic particles from a fluid, e.g. a suspension of kaolinitic clay, and comprises a non-magnetic chamber 1 packed with paramagnetic material in the form of expanded aluminium discs 4. The chamber 1 is surrounded by the coil 5 of a superconducting magnet which provides a field intensity of about 5 Tesla. The particles are subsequently removed by flushing with liquid or air, after removing the magnetic field, possibly using a reducing A.C. current. A second embodiment, Fig. 4 (not shown) has two layers 14, 15, the first 14 of paramagnetic material, e.g. austenitic stainless steel wool, the second 15 of ferromagnetic material, e.g. ferritic stainless steel wool. In use ferromagnetic particles are trapped in the first layer 14, paramagnetic particles in the second layer 15, while non-magnetic particles are carried through with the liquid. Figs. 2 and 3 (not shown) show a concentric arrangement of the embodiment of Fig. 4 (not shown). The packing material 4 may be particulate or filamentary and may have a density which varies along the length of the chamber 1. Preferred dimensions of the particles and the filaments are given, also preferred densities. Other paramagnetic materials mentioned include titanium, vanadium. chromium, manganese, molybdenum, palladium and platinum.

    This invention relates to the field of mineral processing. Known magnetic separator,. Includes a separation chamber filled with a filler, a magnetic network, nozzles of the input material and separation of separation products. Also known is a magnetic separator for separating magnetizable particles from a liquid, including a cam with a filler placed in it, an electromagnetic system placed on the outside of the chamber, a loading and discharge pipes 2. A disadvantage of the known devices is the low efficiency of the separation process. The aim of the invention is to increase the efficiency of the separation process due to the acceleration and more complete implementation of the regeneration process. This goal is achieved by the fact that the filler is made of paramagnetic Material, and in the chamber there is an additional filler made of ferromagnetic material, or the separator is equipped with an additional chamber placed after the MAIN material moving and filled with ferromagnetic material; the filler, and the paramagnetic filler is made of austenitic stainless steel wool or aluminum fibers. FIG. 1 shows the proposed separator, the first embodiment, a longitudinal section; in fig. 2 - separator, second embodiment, longitudinal section; in fig. 3 is the same cross section; in fig. 4 - separator, the third embodiment, extended gap. The separator includes a chamber 1, a loading 2 and a discharge 3 nozzles, a paramagnetic filler. 4, an electromagnetic system consisting of a coil 5 of a superconducting electromagnet, a ferromagnetic frame of vertical 6 and 7 horizontal elements, and the filler is made of austenitic stainless steel wool or from aluminum fibers and fills chamber 1 at 60-98%. The separator according to the second embodiment further includes two perforated and coaxially mounted pipes 8, 9, between which a filler is placed, the filler being placed in two layers 10 and 11. Layer 10
    Made of paramagnetic material, and the layer 11 is made of ferromagnetic material. The layers are separated by a tube 12, which is made with holes. The separator according to the third embodiment is provided with an additional chamber 13 and a partition 14,
    The separator works as follows.
    The source material in the form of a suspension through the nozzle 2 is introduced into the chamber 1, into the second one with the help of a superconducting electromagnet an electric field is created with a strength of

    The magnetized particles are retained by the filler elements, and the valuable liquid is discharged through the pipe 3. When the oil particles coming out of the pipe 3 become at least acceptable, the supply of the starting material is stopped and the magnetic materials are removed and the magnetic materials are removed and the magnetic materials are removed, and the magnetic materials are removed and the magnetic materials are removed and the magnetic materials are removed and the magnetic materials are removed and the magnetic materials are removed and the magnetic materials are removed and the magnetic materials are removed. in case of odd-homogeneous separation of a rHj 4HBa; HHH filler and particles, there is a complete separation of the magnetized h-particles from the bodies, since parag agitite filler does not have a hysteresis loop and its residual magnetization nce zero ..:
    If the initial suspension contains a mixture of ferroaggite and vapor ia; rotten particles, for example a polluted suspension of kaolin clay, it is better to purify it in Separate according to the second or third variant of vyb: ggaenyHa7 ökb torus filler is placed in. The suspension is fed to the separator through the tube 2 and passes First a layer of paramagnetic material, and then through a layer of ferromagnetic material, n1:) nd g | The dyrmalgun particle is covered with a filler made of Tiapa MarH THORO material (in layer 10), and paramagnetic parts are retained in: layer 13, Purified liquid from chamber 3, then isolate chamber 1 from the magnetic layer. Then the cycle is repeated.

    The implementation of a filler from a paramagnetic material allows for a more complete Io. To carry out the regeneration process, since the paramagnetic materials do not have a hysteresis loop, and their residual magnetization is zero. This makes it possible to increase the efficiency of the process of separating magnetizable particles from a liquid ...
