Abstract
A strong permanent-magnetic separator for low-grade iron ore and weakly magnetic iron ore is composed of collecting magnetic pole group, separating magnetic pole group, armatures made of special material and magnetic conveying band loop passing through the gas between magnetic pole group and armature. Its advantages include easy installation, convenient movement, and low cost.
Description
The present invention relates to a kind of benficiation machinery, a kind of permanent magnetic system that adopts can produce higher magnetic induction intensity, is suitable for choosing the magnetic separation benficiation machinery of iron ore of low ore grade and weak-magnetic iron ore.
The magnetic induction intensity that existing permanent magnetic separator produces is generally lower, only is suitable for the choosing of ferromagnetism iron ore is difficult to iron ore of low ore grade and weak-magnetic iron ore are chosen.This just makes in the ore dressing plant, except the ferromagnetism iron ore is chosen, for example to magnetic iron ore (Fe
3O
4) choose, and for mixing in weakly magnetic ore wherein, for example to bloodstone stone (Fe
2O
3) or martite stone (nFeOmFe
2O
3), just can't choose, run off thereby form mine tailing, cause the waste of resource.Adopt electromagnetic separator, can produce higher magnetic induction intensity, but price is too high, be difficult to adopt.In the actual production, need a kind of permanent magnetic separator that can produce, so that choosing to weak-magnetic iron ore or iron ore of low ore grade than high magnetic flux density.
Purpose of the present invention is made a kind of price strong permanent-magnet separator low and that can produce high magnetic induction intensity exactly, chooses the iron ore of weak magnetic, and can from iron ore of low ore grade, reclaim iron ore concentrate, improve the rate of recovery of iron, to the iron ore deposit that runs off, the utilization of redeveloping.
This special magnetic separator, have the magnetic pole of collection group and sort the magnetic pole group, each magnetic pole group all is made of magnetic pole some, and has by the special material manufacturing corresponding with each magnetic pole group with the armature that special shape is arranged, form and be close to enclosed magnetic loop, produce higher magnetic induction intensity thus.In the folder crack of magnetic pole group and armature, annular but surface have hundreds of laterally the carrying section of the magnetic conveyer belt of magnetic stripes and little chase therefrom pass, when iron ore is collected and sorted, also play the effect that iron ore concentrate and row unload mine tailing of transporting.From Fig. 1 as seen, the axis of driving drum 3 and driven cylinder 10 becomes angle α with horizontal line, when driving drum 3 is pressed the rotation of arrow 2 directions, magnetic conveyer belt 4 is from collecting magnetic pole group 9 and collecting between the armature 8 and pass, also pass simultaneously from sorting magnetic pole group 5 and sorting between the armature 6, raw ore slurry is fallen from dispenser 7 on the zone face of magnetic conveyer belt 4, and through to the collection of iron ore with sort, iron ore concentrate is incorporated in the concentrate cover 1 and presses arrow 13 directions and flows out; The mine tailing slurry then goes downstream and is incorporated in the mine tailing cover 11, and presses outside the arrow 12 directions outflow magnetic separator.
This strong permanent-magnet separator, can produce magnetic induction intensity up to 0.8-1 tesla, than the high 3-4 of magnetic induction intensity of general permanent magnetic separator doubly, therefore it not only can be chosen the bloodstone of weak magnetic etc., and can be to produce low-grade of general magnetic separator and iron tailings that go out of use carries out choosing again, to reach abundant recovery iron ore deposit, improve the rate of recovery of iron.This magnetic separator conveniently moving, installation are easily, concentration and granularity requirements to ore pulp are not strict yet, so can directly choose river shoal or the seabeach ore in sand form do not handled through grinding machine, this is that conventional magnetic separator can't accomplish that its economic benefit is fairly obvious naturally.
Description of drawings one embodiment of the present of invention:
Accompanying drawing 1, the magnetic separator principle schematic;
Accompanying drawing 2, magnetic conveyer belt profile;
Accompanying drawing 3 is collected magnetic pole group and the combination schematic diagram of collecting armature;
Accompanying drawing 4 sorts magnetic pole group and the combination schematic diagram that sorts armature;
The embodiment description of drawings.Accompanying drawing 1 is the magnetic separator principle schematic.Ore pulp is from dropping on the flute profile magnetic conveyer belt 4 collecting armature 8 and sort the dispenser 7 between the armature 6, through the collection of collection magnetic pole group 9 with through after sorting the sorting of magnetic pole group 5, because driving drum 3 is pressed the rotation of arrow 2 directions, therefore the iron ore concentrate that obtains of sorting is incorporated in the concentrate cover 1, and presses arrow 13 directions and flow out; And mine tailing flows down along the inclined-plane of inclination alpha and is positioned at the mine tailing cover 11 that produces outside the driven cylinder 10 and takes in, and presses outside the arrow 12 direction outflow machines.Change inclination alpha, can change the iron grade and the output of resultant concentrate.The A-A section is seen accompanying drawing 2; The B-B section is seen accompanying drawing 3; The C-C section is seen accompanying drawing 4.
Accompanying drawing 2 is profiles of magnetic conveyer belt.The transverse cross-sectional shape of magnetic conveyer belt is made up of horizontal component 14 and shelves limit, both sides 15.The whole piece conveyer belt is the flute profile conveyer belt of the no mechanical joint of annular, and ore pulp is limited in can not flowing in grade limit groove conveyer belt outside.For increasing the intensity of conveyer belt, be covered with some special wire ropes 16 at magnetic conveyer belt horizontal component.From longitudinal profile D-D as seen, on the middle glue 19 of adhesive tape horizontal component, be embedded with hundreds of magnetic stripes 17, and magnetize, the little chase 18 of rectangular cross section is arranged between per two magnetic stripes 17, to strengthen sorting capability to iron ore by N-S utmost point rule.
Accompanying drawing 3 is combination schematic diagrames of collecting the magnetic pole group and collecting armature.Magnetic conveyer belt 4 is from collecting magnetic pole group 9 and collecting between the armature 8 and pass, the section of collecting armature 8 becomes the rectangle zigzag, armature is near the part of magnetic conveyer belt 4, form by some protrusion column entities 21 and the empty part 20 of depression, the redundance of ore pulp or non-iron part are flow through by sunk part 20, iron ore concentrate is then by on the zone face of collection surface 22 place's correspondences of protrusion column entity 21 in collection, surface 22 does not contact with adhesive tape 4, adjust both apart from the gap, can obtain different magnetic induction intensity, to satisfy the selected needed magnetic induction intensity of the sort of iron ore.
Accompanying drawing 4 is the combination schematic diagrames that sort the magnetic pole group and sort armature.It is corresponding up and down sorting magnetic pole group 5 and sorting armature 6, when being carried into this moment by magnetic conveyer belt 4 through the preliminary iron ore of collecting, clear water enters from being embedded in the pipe inlet 23 that sorts the armature according to arrow 24, and some apertures 25 flow out from the water pipe horizontal segment 26, be sprayed on the conveyer belt 4, make the impurity that is mixed in the iron ore of tentatively collecting, swept away, can not betransported band and carry by water.After the water flushing, the iron ore concentrate that grade is further enhanced is then carried off upwards operation by magnetic conveyer belt 4.
