SU1233938A1 - Magnetic separator - Google Patents

Description

The invention relates to the separation of materials according to magnetic properties and can be applied to the enrichment of finely divided weakly magnetic iron ores.

The purpose of the invention is to increase the profitability of the separator due to a more complete use of the energy of the magnesium field.

FIG. 1 shows a separator, a general view, with a partial cut; in fig. 2 - the same, top view; in fig. 3 - magnetic system, view from the side of the rotor; in fig. 4 is a section A-A in FIG. 3

The magnetic separator includes rotors 1 with cassettes with ferromagnetic bodies 2 fixed along their perimeter, an open – superconducting magnetically system 3, devices 4–6, respectively, for supplying power and removing magnetic and nonmagnetic products. The rotors I are driven in rotation by the drive 7. The magnetic system 3 is located between the mouths of the arms and consists of 12 solenoids of two types of sizes. Central solenoids 8

wound on one frame, and peripheral 9 - on two frames, which are installed at an angle to each other and to the center. In this way,

The torpas of the solenoids form a curvilinear double-curved surface in the shape of which cryostat I O is made.

The separator works in the same way ,,

The raw material in the form of pulp is loaded into the working zone of the separator to the ferromagnetic bodies 2 from the top through the device 4 for supplying power. In the zone of action of the magnetic field created by the superconducting magnetic system 3., the magnetic particles are attracted to the ferromagnetic bodies 2, and the nonmagnetic ones together with the

They are discharged into the device 6 for removal of the non-magnetic product. When ferromagnetic bodies 2 leave the zone of action of the magnetic field, water is supplied into the gaps between them, which

Slows the magnetic product into the device 5 for removal of the magnetic product.
