0Wftf The invention relates to striving for separating a mixture of diamagnetic and paramagnetic particles of mineral suspensions, mainly for enriching finely disseminated iron ores such as quartzite. , A device is known for separating a mixture of particles of suspensions according to magnetic properties, including a housing made in the form of a trough, a working member in the form of cassettes, a magnetic circuit With the inputs of this device are low separation efficiency, the need for periodic cleaning of the magnetic fraction when the separation process stops. The closest jio of the technical essence and the achieved result to the invention is a magnetic-hydraulic separator, including a body made in the form of a trough, a magnetic system of permanent magnets, a working body, devices for feeding the suspension and withdrawal of separation products 2. A disadvantage of the known separator is low efficiency division, caused by the need to create on the iron ore processing plants complex technological schemes dp additional transfer current magnetic and non-magnetic fields products. -. The aim of the invention is to increase the separation efficiency by counting repeated cleaning of the original; Material in one device. This goal is achieved by the fact that in a magnetic-hydraulic separator, including a casing made in the form of a crib, a magnetic system of permanent magnet, a working body, devices for feeding the suspension and withdrawal of separation products, the working body The angles are mounted vertically with a right angle at the base, with gaps between them, while the permanent magnets are placed on the surface of the prisms. In addition, rectangular prisms are set by inclined planes in the feed direction of the source material. 1 shows a separator, a general view. the sectional view of FIG. 2 is a view A of FIG. A magnetic-hydraulic separator includes a housing 1, made in a video chute, a working member mounted inside a chute and made of cassettes 2 and regiments 3, as well as vertical walls 4 overlapping spiked cassettes 2. The magnetic fraction is removed through the slots 5. In the cage 1 of the separator there are tools for extracting the concentrate b | and tailings 7 enrichment. The cassettes are made of rectangular prisms 8. The fixture 9 provides power to the separator, and the drive 10 provides the reciprocating movement of the separator. The separator works as follows. The original material of separation (slurry) through the device 9 enters the body 1, made in the form of a chute, and then moves in the direction of the working body. In cassettes 2, made of vertical, with a right angle at the base of prisms 8, magnetic separation occurs, and the density of the pulp in the magnetic gap increases and the diamagnetic (with a lower specific weight) particles float to the upper layers of the pulp flow and are withdrawn along the shelves 3 into the tailing device 7. The magnetic fraction is held in the gaps of the cassettes 2 and on the BipixHocTH rectangular prisms 8 and further out through the slit Slot 5 into the concentrate output device b. Vertical walls 4, overlapping the gaps in the cassettes 2, provide support for the pulp from the end; NYM material. Inclined plane prisms. 8 are directed in the direction of supplying the original material, than is achieved. ) The separation sequence, the source material by magnetic properties and specific gravity. The side surfaces of rectangular prisms 8 for enriching finely disseminated iron ores. of quartzite type. With a particle size of quartz and iron oxides of a suspension of 30-40 microns, a developed magnetic-hydraulic separator with four or five magnetic cassettes is used. Moreover, the distance between the slit walls of each cassette is equal to 90-120 mm, the angle of inclination of the wall of the rectangular cassette 25-40, the angle of inclination of the trough body 5-6, the height of the first cassette 1200-1700 mm, the second 800-9.C Ohmm, the third 500-600 mm, the fourth 200300 mm. The distance between adjacent ones. cassettes are taken equal to 8001000 mm. The implementation of the working device in the form of cassettes made of rectangular prisms installed vertically with a right angle at the base with gaps between them makes it possible to increase the separation efficiency, since a large area of the cassettes is used for magnetic separation and the removal of non-magnetic fractions from the separation process.
