This technical scheme desirable following beneficial effect:
1, because the sealing magnetic system that this weak magnetic apparatus for work adopts pole polarity alternately to arrange, magnetic flux is high concentration in magnetizing mediums, magnetic field intensity and gradient on the magnetizing mediums all increase substantially, and existing permanent magnetic wet type cylinder type magnetic separator adopts open type magnetic system, magnetic flux is long by the air-gap distance between magnetic pole, the magnetic energy utilization rate is far below sealing magnetic system, and cartridge type structure intrinsic installation and operation gap, the stainless steel cylinder wall thickness, the abrasive rubber layer is generally all more than 10mm, it has occupied pole-face with the strongest zone of external magnetic field, cause the magnetic energy utilization rate further to reduce, just lower in the magnetic field intensity at the ore pulp base plate place at distance pole surface 50mm place.Thereby, sorting under the identical situation of space magnetic field intensity, gradient, the permanent magnet that the former needs than the latter lack many.General permanent magnet accounts for about 40% of magnetic separator production cost, so, the former production cost than the latter lack many.Again since weak magnetic apparatus for work magnetizing mediums be the filament occupied state, have great surface area, ore pulp by the time can fully contact with magnetizing mediums, the probability that magnetic-particle is caught by magnetizing mediums has reached maximization, thereby the efficiency of separation is very high.And permanent magnetic wet type cylinder type magnetic separator, ore pulp is the corresponding cylinder outer surface contact of cornerite with cylinder bottom magnetic only, the ore pulp that enters the magnetic separation district is under the effect of magnetic field force, the direction of rotation of non magnetic ore particle moving direction and cylinder is opposite, the moving direction of magnetic ore particle is identical with the direction of rotation of cylinder, realizes separating of magnetic ore particle and non magnetic ore particle with this.The magnetic ore particle depends on magnetic force and ore pulp resistance that it is suffered with the mobile effect of cylinder, and the magnetic force that is subjected to apart from the near magnetic ore particle of cylinder outer surface is big, the ore pulp resistance is little, and is mobile effective, on the contrary mobile weak effect.Because ore pulp and cylinder outer surface contact area are limited, owing to the certain thickness of contact need of ore pulp and cylinder outer surface, the ore pulp major part that enters the magnetic separation district is apart from the cylinder outer surface distance again, and separating effect is poor, thereby overall separation efficient is far away from this weak magnetic apparatus for work.Also because the magnetic cording that this weak magnetic apparatus for work pole polarity is alternately arranged has " magnetic stirs " effect, the magnetic linkage that mechanical iron that pulverizing process produces and ferromagnetism ore particle are aggregated into is loosening, thereby the magnetic ore particle is further separated with non magnetic ore particle, can when the nonmetallic ore deironing, improve product yield, when the iron ore magnetic separation, improve end product quality.Described permanent magnetic wet type cylinder type magnetic separator sees 32～36 pages of metallurgical industry publishing house the 5th printings in 2005 " magnetoelectricity ore dressing " for details.
2, because chain ring type magnetizing mediums conveying device provides magnetizing mediums level, a straight line to move, the magnetic concentration working section length can reach the environment of 7 meters magnetic concentration working, thereby, along the magnetizing mediums moving direction, the length of last lower magnetic pole can be provided with on demand, also can whether rationally reach the mode of the spacing requirement employing multistage splicing of flushing water according to processing difficulty or ease, processing charges.Because last lower magnetic pole is a box-shaped, compares with the arc magnetic pole of upright ring type magnetic separator, difficulty of processing is little, processing charges is low.Chinese patent ZL01242984.8 has announced a kind of pulsating high gradient magnetic separator with vertical ring, wherein, " magnetic is that cornerite changes 100 °～120 ° into by 90 ° to Instructions Page 3, and magnetic is after cornerite increases; magnetizing mediums makes ore obtain sufficient sorting by ore dressing district time lengthening.Concentrate grade has improved 2～5 percentage points, and the rate of recovery of valuable mineral has improved 5～10 percentage points." this example explanation: prolong the time of magnetizing mediums, can improve the efficiency of separation by the magnetic separation district.But magnetic is cornerite increase to 120 ° after, increase magnetic again and be just difficulty relatively of cornerite.So the way of having taked to increase upright ring diameter improves the upright ring outer perimeter that magnetic is the cornerite correspondence, to strengthen the length in magnetic concentration working district.Oneself has produced the upright ring type magnetic separator of 2 meters of diameters as China company, and has brought into play good effect in the ore dressing industry.But increase the production cost that upright ring diameter will increase exponentially magnetic separator.Magnetic separator as upright ring diameter 1000mm, the heavy 6t of main frame, the heavy 2.22t of maximum part, the magnetic separator of thirty years of age ring diameter 2000mm, the heavy 50t of main frame, the heavy 14t of maximum part, both compare, though from material input, processing charges, or transportation install, the latter's construction cost will be the former doubly a lot.And chain ring type magnetizing mediums conveying device, the length that improves the magnetic concentration working district only increases the length of chain 2 and magnetizing mediums box 3, under to the little situation of complete machine production cost influence, has solved the length issue in magnetic concentration working district.And the used unit overwhelming majority is a universal standard part, has not only reduced the production cost of magnetic separator significantly, has also simplified the production technology and the difficulty of processing of magnetic separator greatly.The machine that the arc magnetic pole of described upright ring type magnetic separator sees Figure 27, described upright ring type magnetic separator for details heavily waits the addressable www.Slon.com.cn/about.ht of index website, and for details see attached table 1, " SLOn pulsating high gradient magnetic separator with vertical ring important technological parameters list ".
3, the straight pin skewer of the attached plate chain 2 of chain ring type magnetizing mediums conveying device band is gone in the both sides earhole of magnetizing mediums box 3, and it is " simply supported beam " of bearing with chain 2 that magnetizing mediums box 3 is equivalent to two ends, and this " simply supported beam " has best stress.The change of thirty years of age ring type magnetic separator is formed by middle ring flat-plate, side ring plate, wheel hub, disc assembly welding, and magnetizing mediums is loaded in " box " of side ring plate and middle ring flat-plate and dividing plate formation.Owing to should " box " take root from disc, be equivalent to the disc is " cantilever beam " of bearing, this stability of structure is poor, be reliably working after equipment is put into operation, must take strengthening measure with raising rigidity and intensity, thereby, production cost is greater than chain ring type magnetizing mediums conveying device, and the magnetizing mediums box 3 of chain ring type magnetizing mediums conveying device be for can adorn removable structure, keep in repair very convenient, the long service life of equipment.The structure of upright ring type magnetic separator magnetizing mediums box sees Chinese patent CN86106144A figure four, Chinese patent ZL01242984.8 Fig. 7, Fig. 8 for details.
When 4, the weak magnetic mineral of strongly magnetic mineral and process roasting adopts the drum type brake magnetic separator to carry out magnetic separation, after the strongly magnetic mineral of particulate or microfine enters the magnetic field of magnetic separator, form magnetic linkage or flux along magnetic line of force orientation.The demagnetizing factor of thin magnetic linkage is little more than individual particle, and its magnetic induction intensity is than high many of individual particle.After it leaves magnetic field, still preserve the intensity of magnetization of oneself, particulate or microfine particle form magnetic linkage or floc sedimentation as a result.When adopting stage grinding stage grading stream to become, because entering, a part of magnetic linkage or magnetic group make the partition size chap in the classifier overflow, influence the sorting result of next stage grinding-classification operation, separation index is descended.The existence of magnetic group or magnetic linkage also makes the concentrate filter cake moisture content increase.Therefore, when carrying out the magnetic separation of ferromagnetism fine mineral, should be equipped with and take off the magnetic apparatus for work with the drum type brake magnetic separator.Existing demagnetizer is: put the turriform coil that is connected with alternating current outside the nonmagnetic substance pipe, produce the alternating magnetic field that amplitude is successively decreased along the coil centerline direction.When ore pulp passed through pipeline, under the outside magnetic field effect, the magnetic ore particle was subjected to taking off repeatedly magnetic, loses remanent magnetism at last.This demagnetizer is open type magnetic system, and magnetic flux is long through the distance of air section, and magnetic resistance is big, and the magnetic energy utilization rate is low, the power consumption height.Because chain ring type magnetizing mediums conveying device " going up the magnetic concentration working district " has enough length, can along the magnetizing mediums moving direction be provided with a plurality of with the silicon steel sheet be magnet exciting coil arranged on iron core, each iron core take off the magnetic apparatus for work, the number of turn of magnet exciting coil is successively decreased along the magnetizing mediums moving direction, and iron core and magnetizing mediums constitute closed magnetic and be.But after feeding the alternating current of regulating frequency in the magnet exciting coil, produce the descending alternating magnetic field of amplitude along the magnetizing mediums moving direction, magnetizing mediums in moving and the ferromagnetism ore particle that upward adsorbs thereof are taken off magnetic repeatedly by this alternating magnetic field, lose remanent magnetism at last.Because adopted closed magnetic to be, magnetic resistance is little, magnetic energy utilization rate height.Owing to take off background magnetic field intensity that the magnetic operation needs in 2000 Gausses, by silicon steel (silicon 4%) magnetization curve as can be known, this moment, the magnetic induction intensity of silicon sheet core reached maximization again.Compare with the drum type brake magnetic separator, not only saved and taken off the magnetic apparatus for work, and, can obtain best power savings and take off the magnetic effect.Describedly take off the magnetic operation and demagnetizer sees 26 pages, 41 pages, 42 pages of metallurgical industry publishing house the 5th printings in 2005 " magnetoelectricity ore dressing " for details.
5, permanent-magnetic cylindrical type magnetic separator multistage magnetic concentration working technology is adopted in the wet magnetic separation operation of ferromagnetism and medium magnetic mineral; And the wet magnetic separation operation of particulate weak magnetic mineral after employing permanent-magnetic cylindrical type magnetic separator is removed ferromagnetism and medium magnetic ore particle earlier, is carried out multistage high intensity magnetic separation operation technique with upright ring type high gradient magnetic separator.No matter that a kind of technology all needs many magnetic separators to realize.The magnetic concentration working district arranges demagnetization apparatus for work, recoil apparatus for work on chain ring type magnetizing mediums conveying device, magnetic apparatus for work, middle magnetic apparatus for work a little less than the magnetic concentration working district arranges down, then become a kind of weak, middle magnetic separator that carries out the multistage operation, be used to handle ferromagnetism and medium magnetic mineral; The magnetic concentration working district arranges demagnetization apparatus for work, recoil apparatus for work on chain ring type magnetizing mediums conveying device, magnetic apparatus for work, middle magnetic apparatus for work, the strong magnetic apparatus for work of multistage a little less than the magnetic concentration working district arranges down, then become a kind of strong magnetic separator that carries out the multistage operation, be used to handle weak magnetic mineral.Thereby, only with a chain ring type magnetic separation machine that can carry out the multistage operation, just can realize the magnetic concentration working of above-mentioned two kinds of technologies, can reduce construction fund significantly.
