According to the technical scheme, the dry coal separating machine comprises a rack and a plurality of magnetic rollers with axes parallel to one another, the magnetic rollers are installed in the rack in sequence from top to bottom, the next magnet roller receives tailings of the last magnet roller, the rotating direction of the next magnet roller is opposite to the rotating direction of the last magnet roller, a feeding hopper is arranged at the upper portion of the uppermost magnetic roller, a tailing discharging hopper is arranged at the lower portion of the lowermost magnetic roller, and the two sides of the rack are both provided with concentrate discharging hoppers. According to the material layer repeating overturn type dry coal separating machine, multiple stages of the magnetic rollers are used to conduct magnetic separation on magnetic iron ores in sequence, the rotating directions of every two adjacent magnetic rollers are opposite, a material layer is fully loosened in the whole magnetic separating process due to repeating overturn, therefore, the magnetic agglomeration of the material layer is effectively eliminated, and the selected probability of the magnetic particles is increased. The dry coal separating machine can not only throw away useless gangue but also avoid running-away of magnetic iron, and the grade of concentrate is greatly improved.
Description
Technical field
The present invention relates to a kind of can jettisoning gangue useless, the iron ore dry-dressing machine effectively avoiding Armco magnetic iron to run off again, belongs to separation technology field.
Background technology
For the magnetic iron ore reaching production-grade, the key of restriction Ultra-low-grade magnetite application is that head grade is low, ratio of concentration is large, cost of winning is high.In order to reduce cost of winning, people's trial dry-dressing machine on the basis of magnet drum sorts the fine ore of particulate, and this dry-dressing machine, while throwing is useless, has enrichment to mineral, improves Beneficiation Feed Grade.But iron ore particle can not be separated with gangue by traditional dry-dressing machine effectively.After preliminary election throwing is useless, fine work ore deposit is still containing a large amount of gangue, and in mine tailing, ferromagnetic content is still very high, does not only reach consumption reduction object, and causes the loss of resource.Therefore be badly in need of at present a kind of can gangue that effectively jettisoning is useless, the dry-dressing machine that minimum Armco magnetic iron runs off can be ensured again.
Summary of the invention
The object of the invention is to the drawback for prior art, provide a kind of can jettisoning gangue useless, the bed of material effectively avoiding Armco magnetic iron to run off again convertible dry-dressing machine repeatedly.
Problem of the present invention realizes with following technical proposals:
A kind of bed of material convertible dry-dressing machine repeatedly, formation comprises multiple magnet drums that frame and axis are parallel to each other, described multiple magnet drums are arranged in frame from top to bottom successively, next magnet drum receives the mine tailing of a upper magnet drum and contrary with the direction of rotation of a upper magnet drum, the top of going up magnet drum is most provided with feed hopper, descend most the bottom of magnet drum to be provided with mine tailing discharge bucket, the both sides of described frame are equipped with concentrate discharge bucket.
The above-mentioned bed of material is convertible dry-dressing machine repeatedly, the movable cutting plate of inclination is equipped with between any two adjacent magnet drums, described movable cutting plate receives the mine tailing of its top magnet drum, and its upper limb is connected with frame, and lower edge is corresponding with the forward feed side of bottom magnet drum.
The above-mentioned bed of material is convertible dry-dressing machine repeatedly, the drive unit of described magnet drum comprises motor, reductor and drive line angle band, described motor and speed reducer is fixed in frame, and the power shaft of reductor docks with the output shaft of motor, and the output wheel of reductor drives multiple magnet drum by drive line angle band.
The above-mentioned bed of material is convertible dry-dressing machine repeatedly, and two side wall lower ends being parallel to magnet drum axis of described feed hopper are equipped with movable regulating plate, and described movable regulating plate is connected with the sidewall of feed hopper by bolt.
The present invention utilizes multistage magnet drum to carry out magnetic separation to magnetic iron ore successively, and the direction of rotation of adjacent two-stage magnet drum is contrary, make the bed of material in whole magnetic separation process fully loose because constantly overturning, thus effectively eliminate the magnetic coagulation of the bed of material, add the selected probability of magnetic-particle.This dry-dressing machine can jettisoning gangue useless, Armco magnetic iron can be avoided again to run off, substantially increase the grade of concentrate.

Detailed description of the invention
According to the difference of each magnet drum magnetic separation mode, the present invention has two kinds of structures, is respectively the downflow type bed of material convertible dry-dressing machine and the downflow type bed of material convertible dry-dressing machine repeatedly repeatedly.
Referring to Fig. 1, the downflow type bed of material repeatedly convertible dry-dressing machine comprises frame 1, feed hopper 2, movable regulating plate 3, magnet drum 4, left concentrate discharge bucket 5, right concentrate discharge bucket 6, mine tailing discharge bucket 7, movable cutting plate 8 and drive unit.Magnet drum 4 arranges multiple, and they are arranged in frame 1 from top to bottom successively, and the contrary and placement of staggering of adjacent magnet drum 4 direction of rotation, the mine tailing of a upper magnet drum drops on the forward feed side sliding to next magnet drum after on movable cutting plate.There is concentrate discharge bucket magnet drum both sides, and mine tailing discharge bucket 7 is arranged at frame 1 bottom, and feed hopper 2 is arranged at top, and feed hopper 2 opening part has movable regulating plate 3, depending on determining openings of sizes to miner's condition.The rotary speed of magnet drum 4 by Frequency Converter Control, according to required concentrate grade, mine tailing yield ratio, the rotating speed of user's conditioning equipment voluntarily.When utilizing this dry-dressing machine process magnetic iron ore, the bed of material overturns repeatedly, through repeatedly magnetic separation, effectively promotes being separated of iron particle and gangue, greatly reduces ferromagnetic content in gangue, reach the object of consumption reduction.
Fig. 2 is the structural representation of the reverse-flow bed of material convertible dry-dressing machine repeatedly, and its operation principle and the downflow type bed of material repeatedly convertible dry-dressing machine roughly the same, have just lacked movable cutting plate 8, and the mine tailing of a upper magnet drum directly drops on the adverse current feeding side of next magnet drum.
Fig. 3 is drive unit schematic diagram of the present invention, motor via reducer 10 and drive line angle band 9 form driving relationship with each magnet drum 4, motor is by Frequency Converter Control, its power is sent to magnet drum 4 through reductor 10 and drive line angle band 9, the rotating speed of magnet drum is suitably adjusted, to reach best separating effect according to mineral aggregate situation.
Adopt above technical scheme, magnet drum in opposite directions stacked staggers placement, and mineral aggregate is after one-level magnetic separation, and its mine tailing, as the alternative mineral aggregate of next stage, enters secondary magnetic separation.Because staggering in opposite directions of magnet drum stacks, be equivalent to the bed of material to overturn.After multi-stage magnetic separation overturns repeatedly, the fully loose bed of material, is conducive to breaking magnetic coagulation, adds the selected probability of magnetic-particle, further reduce the content of magnet grains in mine tailing, decrease the last person to the utmost and lead, turn improve the grade of concentrate simultaneously.
