Abstract
The invention discloses a magnetic separator for concentration. The magnetic separator for concentration comprises a groove body, a roller, magnetic systems and a bracket, wherein a scavenging region and an ore carrying region are respectively formed between the outer side of the roller and the groove body; and the magnetic systems corresponding to the ore carrying region and the scavenging region are respectively a multipole high-gradient magnetic system and a high-interaction depth magnetic system. Since part of the magnetic system, corresponding to the ore carrying region, is the multipole high-gradient magnetic system, magnetic turning movement times of adsorbed magnetic materials is increased along with the roller during the movement process in the ore carrying region, magnetic turning frequency is improved, thickness of a bed of material is reduced, and thus, impurities are discharged, and concentrate grade is promoted; high gradient has the effect of improving the adsorption capability and preventing superfine granulometric class materials from being thrown away during the magnetic turning process. Part of the magnetic system corresponding to the scavenging region is the high-interaction depth magnetic system which can guarantee that the superfine granulometric class materials can be captured effectively in the scavenging region. By the magnetic separator for concentration, the granulometric class materials, is difficultly captured by a normal magnetic separator, can be recycled effectively, incomplete separation of tailings is prevented, and high concentrate grade is realized.
Description
Technical field
The invention belongs to magnetic separator technical field, be specifically related to a kind of cleaning magnetic separator.
Background technology
Magnetic separator is a kind of iron ore beneficiation equipment, and be usually made up of cylinder, magnetic system, cell body, frame, material feeding box, concentrate hopper and drive unit etc., operation principle utilizes the running of magnetic system magnetic fields and cylinder that the magnetic mineral in ore pulp is sorted out.The arrangement that magnetic ties up to circumferencial direction is generally N, S pole and replaces arrangement form.The feed preparation unit size of magnetic separator is generally-0.074mm, 20% ~-0.043mm, 98%, in this particle size range, magnetic mineral can automatically form magnetic linkage form along the magnetic line of force in the magnetic field of magnetic separator, with the form of magnetic linkage adsorb by magnetic field, the form of magnetic linkage can strengthen the absorption affinity of magnetic mineral in magnetic field.Simultaneously because magnetic pole arrangement is in N, S pole alternant, be fed forward in process by the magnetic material in absorption along with cylinder, often will have a magnetic switching process along the magnetic line of force through a magnetic pole, thus the impurity in magnetic linkage is discharged.Along with milling ore character is deteriorated, ore disseminated grain size is more and more thinner, the feed preparation unit size of magnetic separator even reaches-0.025mm (500 order), 95%, because feed preparation unit size diminishes, cause material argillization phenomenon serious, the magnetic of a lot of micro-size fraction material dies down, and in magnetic field, be difficult to the form forming magnetic linkage, magnetic separator is difficult to collecting, easily washed away by current in magnetic separation process, cause valuable mineral to run tail.Simultaneously because granularity diminishes, ore pulp viscosity strengthens, and causes impurity component to be brought in concentrate, affects concentrate grade.
Summary of the invention
The object of this invention is to provide a kind of micro-size fraction cleaning magnetic separator, it can effectively sort micro-size fraction material, obtains desirable concentrate grade and tailings grade.
To achieve these goals, the technical solution used in the present invention is: this magnetic separator comprises two ends and is respectively equipped with the cell body of material feeding box and concentrate hopper, cylinder and support; The bottom of drum cavity is provided with the many groups magnetic system along inner wall of rotary drum distribution; Cylinder bottom is crouched in cell body, is formed respectively into mining area, scan district, overflow area and transport mining area outside it and between cell body; Be characterized in: with fortune mining area and scan magnetic system corresponding to district and be respectively multipole High-gradient Magnetic system and high depth of interaction magnetic system.
Advantage of the present invention is: the present invention is multipole High-gradient Magnetic system with magnetic corresponding to fortune mining area, can allow by the magnetic material in absorption along with cylinder is in the motion process of fortune mining area, magnetic flip-flop movement number of times increases, magnetic toggle frequency improves, thickness of feed layer reduces, thus is discharged by impurity component, promotes concentrate grade, the effect of high gradient strengthens adsorption capacity, prevents micro-size fraction material from being got rid of in magnetic switching process.The magnetic corresponding with scanning district is high depth of interaction magnetic system, can ensure that micro-size fraction material is effectively caught scanning district.The present invention effectively can reclaim the micro-size fraction material that common magnetic separator is difficult to collecting, ensure that mine tailing does not run tail, obtains high concentrate grade simultaneously, and sorting result is remarkable, and what solve fine material stage material sorts a difficult problem, is worth applying widely.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
As shown in the figure, the present invention includes two ends and be respectively equipped with the cell body 2 of material feeding box 1 and concentrate hopper 8, cylinder 3 and for supporting their support 9.The bottom of cylinder 3 inner chamber is provided with the many groups magnetic system 4 along the distribution of cylinder 3 inwall; Cylinder 3 bottom is crouched in cell body 2, is formed into mining area 10 respectively, scan district 12, overflow area 13 and transport mining area 7 outside it and between cell body 2.With fortune mining area 7 and scan magnetic system corresponding to district 12 to be respectively multipole High-gradient Magnetic be 5 and high depth of interaction magnetic system 11.Above-mentioned high depth of interaction magnetic system 11 is 2 magnetic poles.Above-mentioned multipole High-gradient Magnetic is 5 is 5 magnetic poles.Above-mentioned magnetic system 4 is the large angle wrapping structure of 145 ° for disk pack angle, adopts this kind of large angle wrapping structure, makes top, overflow area 13 also have magnetic system correspondence to be formed and reclaims magnetic system 14.This recovery magnetic system 14 can cylinder stick the magnetic material of taking home and enter into before overflow area 13, prevent magnetic material from entering in mine tailing, avoid the generation of drum having material phenomenon.Be provided with 2 concentrate drip washing water pipes 6 for spraying washing water at fortune mining area 7 place, material coordinates the flushing of washing water when magnetic flip-flop movement, discharged by impurity component.
