Description
One, technical field
Mineral processing method of iron ores.
Two, background technology
Still there is not similar beneficiation method at present.The patent of invention that I have applied for magnetic sheet formula magnetic separator on December 19th, 2012, application number is 201210553052.2, has applied for the utility model patent of identical content simultaneously, application number is 201220704199.2.Because there is defective in claims of above-mentioned application documents, have exceeded the content of former specification after the modification again, therefore apply for this patent, to remedy the deficiency of application documents last time.This patent application is the subsidiary patent application of patent application last time.This patent application and patent application last time do not coexist with, the intensity of the high-strength magnetite that magnetic sheet is installed has been determined in this patent application, has determined to use magnetic sheet to sort the recovery rate in ore-dressing of the method for micromagnetism iron ore.
Three, summary of the invention
Use magnetic sheet to sort the method for iron ore, also can be described as the method that sorts iron ore with magnetic sheet formula magnetic separator.Described magnetic sheet is exactly one in company on an iron sheet plate or other plate, puts magnetite, existing magnetic sheet the Lian Yihang of delegation.Also the space can be arranged between the magnetite.Magnetic sheet also can be magnetic board and without magnetite.When the mixing water that contains iron powder flow through above magnetic sheet, iron powder will be adsorbed by magnetic sheet.After iron powder was adsorbed by magnetic sheet, motor-driven powder-wiping plate scraped iron powder, was entered back the powder groove by the iron powder that scraped, added second magnetic sheet that enters position under first magnetic sheet behind the clear water.The iron powder that scrapes from second magnetic sheet enters high frequency sieve or other sieve sheet after adding clear water, iron powder through the sheet processing of sieving, meal returns ball mushroom machine or other disintegrating apparatus, fine powder enters the 3rd magnetic sheet, entering the 4th magnetic sheet after the 3rd iron powder that magnetic sheet scrapes adds clear water, namely is the finished product iron powder from the 4th iron powder that magnetic sheet scrapes.
Use magnetic sheet to sort the method for iron ore, broken and broken with pigment the micromagnetism iron ore exactly after, the equipment that combines with motor-driven powder-wiping plate with magnetic sheet carries out magnetic separation, and recovery rate in ore-dressing is reached more than 60%.If put the high-strength magnetite of monolithic that a lot of Surface field intensity surpass 1400 Gausses at every magnetic sheet, the method for using magnetic sheet to sort iron ore so is the best equipment that sorts the micromagnetism iron ore.Described recovery rate in ore-dressing refers to the percentage of the quantity of metal in the quantity of the useful constituent in the concentrate and the raw ore.
Present magnetic separation operation is by behind the first road magnetic separator mostly, enters the high frequency sieve, enter the second road magnetic separator again, the iron powder that comes out from the second road magnetic separator is finished product, because general magnetic separator all can not be elected iron powder fully, selects machine so will tail be installed in waste way mostly.Machine of magnetic sheet formula magnetic separator can replace the first traditional road magnetic separator, the second road magnetic separator, high frequency sieve, tail selects four machines of machine.And the iron powder that magnetic sheet formula magnetic separator is selected is of high grade, and cost is economized on water nearly one times not as good as a general magnetic separator, and economize on electricity is more than one times.Because containing the mixing water of iron powder is to be close to magnetite to flow through, magnetic a little iron powder can both be adsorbed by magnetic sheet, therefore magnetic sheet formula magnetic separator is particularly suitable for selecting the iron ore of little magnetic, magnetic sheet formula magnetic separator can avoid iron powder to run off effectively, mention the ore dressing rate the highest, thereby the saving mineral resources improve the performance of enterprises.Magnetic sheet formula magnetic separator is drawn large junk for the river course can not arrange the sieve sheet, and the iron sand of selecting can directly be sold as the finished product iron powder.
Magnetic sheet formula magnetic separator is mainly scraped motor-driven powder plate, sieve sheet, dynamical system by four magnetic sheets, four and is formed.As shown in Figure 1, 2.
(1) magnetic sheet: company is one on iron sheet plate or other plate, puts magnetite, existing magnetic sheet the Lian Yihang of delegation.Also the space can be arranged between the magnetite.Magnetic sheet also can be magnetic board and without magnetite.The mixing water that the front end of magnetic sheet had both contained iron powder flows into end connection bypass channel, and mixing water can be flowed on magnetic sheet equably.Bypass channel also can be above magnetic sheet.The both sides of magnetic sheet respectively connect a sideboard identical with magnetic sheet length, and mixing water can not be flowed to both sides.The outside of sideboard has a plurality of small springs to be fixed on the spring seat, and the push jack on the powder-wiping plate can be pushed open sideboard, and after powder-wiping plate left, small spring again can be the sideboard original position of slippaging.Below the sideboard on the both sides of magnetic sheet, the powder groove is arranged back fixedly, after powder-wiping plate was pushed sideboard open, and iron powder flows into back the powder groove, clear water was just in the bypass channel that returns before iron powder in the powder groove rushes at next magnetic sheet.Generally speaking, the front end height of magnetic sheet, the rear end is low, and mixing water can be flowed down smoothly, and key is that magnetic sheet is more steep, and the iron powder of selecting is more clean.It can be parallel returning the powder groove, also can be slightly high at the minimum end of magnetic sheet, makes back iron powder in the powder groove can flow in the bypass channel of next magnetic sheet smoothly or flows directly on next piece magnetic sheet.In order to reduce the height of magnetic sheet formula magnetic separator, the bypass channel on every magnetic sheet both sides can be divided into two sections, and the iron powder in the bypass channel of magnetic sheet front end both sides flows into the front end of piece magnetic sheet down, and the iron powder in the bypass channel of both sides, magnetic sheet rear end flows into the rear end of piece magnetic sheet down.Seldom there is iron powder the magnetic sheet rear end, because most iron powder is all adsorbed by the front end of magnetic sheet.Four magnetic sheets are arranged above and below, and the sieve sheet is arranged with middle.Four magnetic sheets can be big or small identical, also can omit weak point by following piece magnetic sheet, arrangement after following piece magnetic sheet slightly leans on than last piece magnetic sheet.
(2) motor-driven powder-wiping plate: the powder-wiping plate that with machinery is power is exactly motor-driven powder-wiping plate.Every magnetic sheet top arranges motor-driven powder-wiping plate.Powder-wiping plate can be made of corrosion resistant plate, in order to avoid adsorbed by magnetic sheet.Wide of motor-driven powder-wiping plate pastes on the magnetic sheet and stands vertically, also distance slightly.The face of powder-wiping plate is parallel with the face of magnetic sheet both sides sideboard.Two faces of powder-wiping plate respectively weld a plurality of square little push jacks.One end of the push-pull shaft of dynamical system is fixed on the one side of powder-wiping plate, drives motor-driven powder-wiping plate side-to-side movement.
(3) sieve sheet: the sieve sheet can sieve sheet with high frequency sieve or other.The sieve sheet can be arranged in the centre of four magnetic sheets, just second magnetic sheet below.In order to reduce the height of magnetic sheet formula magnetic separator, the sieve sheet should not be steep excessively, but might make the crude iron powder stop up the sieve sky of sieve sheet like this, so can above the sieve sheet several roads scour without sediment motion be set more.If wide two chis of magnetic sheet, long one meter, the magnetic sheet formula magnetic separator of specification can be selected 100 tons of Iron Ore Powder every day at least like this, but width is the sieve sheet of two chis but can not select 100 tons of Iron Ore Powder every day, so the two layer screen sheet can be set, the iron powder that scrapes from second layer magnetic sheet is divided into two strands, enters the two layer screen sheet respectively.Base plate under the ground floor sieve sheet can be divided into two sections, the thin iron powder that the epimere base plate is collected can sieve the middle sky of opening of sheet by the second layer and enter the epimere that the second layer sieves the sheet base plate, and the iron powder under second layer sieve sheet epimere sieve flows directly into the top of the 3rd layer of magnetic sheet.The thin iron powder that the hypomere base plate is collected can sieve the hypomere that sky enters second layer sieve sheet base plate of opening of sheet lower end by the second layer.Base plate under the second layer sieve sheet also can be divided into two sections, and the opening of two sections base plates just goes out an end of fine powder towards the upper end of the 3rd layer of magnetic sheet.
(4) dynamical system: dynamical system comprises that motor or other power, reductor, large eccentricity wheel, push-pull arm, riser, transverse slat, push-pull shaft form.Output shaft at reductor connects the large eccentricity wheel, and the diameter of large eccentricity wheel equates with the width of magnetic sheet.Push-pull arm is connected on the large eccentricity wheel versatilely.Riser vertically is connected the other end of push-pull arm versatilely.The face of four transverse slats respectively with four sideboards face parallel, four transverse slats are connected the correspondence position on the riser.Every transverse slat connects the push-pull shaft more than two, and the other end of push-pull shaft connects powder-wiping plate.In order to reduce the floor space of magnetic sheet formula magnetic separator, riser, transverse slat and push-pull shaft can be located at the other end of magnetic sheet, and the push-pull arm that the large eccentricity wheel connects is by the riser on the following connection opposite of sieve sheet.
