As shown in Figure 1, dry type of the present invention many magnetic system permanent magnetism roller magnetic separator is used for a large amount of ferromagnetism materials of process continuously after high-pressure roller mill extrudes, and the wholegrain level ferromagnetism ore of 0mm-20mm is put into magnetic separator. Being provided with permanent magnetism roller in magnetic separator housing 1, permanent magnetism roller comprises the outer cylinder 4 of rotation and is positioned at the axle core 5 at middle part, and outer cylinder 4 counterclockwise rotates, and axle core 5 is in the state maintained static always. The top of magnetic separator housing 1 is provided with feeder 2 and dust arrester installation 3; Combination magnetic system 6 it is provided with in permanent magnetism roller. The iron ore fed from feeder 2 sends to the top area of permanent magnetism roller by feeder, and the layering that is magnetized under the effect in magnetic field, permanent magnetism roller magnetized area. The mode of its magnetization layering is: ferromagnetism particle is magnetized and is connected into magnetic linkage each other, is finally adsorbed on the innermost layer of roller surface; Although the intergrowth particle of weak magnetic is also magnetized but can not form magnetic linkage each other, finally it is adsorbed on the outside of ferromagnetism magnetic linkage; Non magnetic gangue particle has then been extruded into outermost layer by above magnetic-particle. The storied placement state of this kind of material is conducive to ensuing throwing tail to sort process.
Described combination magnetic system 6 comprises default magnetic system 61, throw tail magnetic system 62 and selected magnetic system 63, default magnetic system 61, throws tail magnetic system 62 and selected magnetic system 63 externally cylinder 4 turning direction, namely counterclockwise arranges successively.The lower section of magnetic separator housing 1 is provided with mine tailing mouth 7, middle mine mouth 8 and concentrate mouth 9. Default magnetic system 61 is corresponding with the material inlet of feeder 2, throws tail magnetic system 62 corresponding with mine tailing mouth 7, and selected magnetic system 63 is corresponding with middle mine mouth 8, is provided with to connect and expects swash plate 10 between mine tailing mouth 7 and middle mine mouth 8. The afterbody of selected magnetic system 63 is corresponding with concentrate mouth 9. The mouth correspondence of gathering dust of described dust arrester installation 3 is arranged at the top of concentrate mouth 9.
Presetting the follow-up throwing tail operation that the magnetization layering of material also is conducive to throwing tail magnetic system by magnetic system, the magneticstrength presetting magnetic system is 32-500kA/m. In order to ensure that all magnetic materials can be held, thus obtaining the mine tailing that magnetic iron level is very low, the magneticstrength of described throwing tail magnetic system arranges very high, throws the magneticstrength >=400kA/m of tail magnetic system. Such design, sorting between ferromagnetism material and weak magnetic material and non-magnetic material can be made must to compare thoroughly, reduce the impact that subsequent fine is elected to be industry by non-magnetic material as far as possible, can avoid simultaneously to non-magnetic material repeat sort, to reduce the overall energy consumption of whole system, and improve the concentrate grade of mineral.
In order to promote concentrate grade as much as possible, it is achieved being effectively separated between ferromagnetism particle and sub magnetic debris, described selected magnetic system 63 is become with several weak magnetic areas territory alternate combinations by territory, several strong magnetic areas; The magneticstrength in territory, strong magnetic area is 130-160kA/m, the magneticstrength≤50kA/m in territory, weak magnetic area. The arc length in territory, strong magnetic area is 80-100mm, the arc length≤130mm in territory, weak magnetic area. When magnetic material enters into the strong magnetic working range in selected district, all magnetic-particles all can be attracted to roller surface; And when magnetic material enters into the weak magnetic working range in selected district, owing to the magneticstrength in this region is extremely faint, magnetic field suction is also very little, the magnetic-particle of the overwhelming majority will start to depart from roller surface along para-curve track under the effect of self gravitation and mass force, just when these magnetic-particles depart from roller surface certain distance, they have entered into again next adjacent territory, strong magnetic area, can be again adsorbed onto the surface of roller again. Like this, the repetition process these magnetic-particles constantly being picked up-falling-pick up-fall by selected magnetic system, make the separating machine meeting obtained between ferromagnetism particle and sub magnetic debris repeatedly, solve the traditional difficult problem that magnetic wraps up magnetic separation circle such as being mingled with magnetic so that concentrate grade is promoted greatly.
It is without magnetic zone of transition 11 at the rear of described selected magnetic system 63. magnetic material is when the rotation along with cylinder continues to enter into selected district, can start to depart from roller surface along para-curve track under the effect of self gravitation and mass force, just when these magnetic-particles depart from roller surface to certain distance, they have entered into the territory, first strong magnetic area of selected magnetic system, the particle that part magnetic is stronger will be adsorbed onto the surface of roller again, the more weak mineral grain of magnetic then can drop on the upper surface connecing material swash plate being positioned at below without magnetic transitional region to be continued to slide downwards, the mineral grain that part magnetic is slightly strong is wherein had likely again to be adsorbed to the surface of roller under the action of a magnetic field of selected magnetic system, the very weak particle of all the other magnetic then finally can drop into the middle mine mouth of lower section.
In addition, described selected magnetic system 63 is arc, and the radian corresponding to its arc is the 30-110 degree taking axle core 5 as the center of circle, and described default magnetic system 61 is arc, and the radian corresponding to its arc is the 30-110 degree taking axle core 5 as the center of circle.Described throwing tail magnetic system 62 is arc, and the radian corresponding to its arc is the 30-110 degree taking axle core 5 as the center of circle. Or other radian scope can also reach magnetic separation effect. Permanent magnetism roller adopts the mode that many magnetic system combines, its total Guide canel >=240 °; Utilize the big cornerite magnetic architecture that this magnetic separator is exclusive so that sorting is more efficient, it is possible to sub-elect full Iron grade iron ore concentrate high as far as possible, mine tailing that magnetic iron level is low as far as possible, and containing the more chats of intergrowth. This not only makes the working efficiency of the sorting operation of magnetic mineral have great lifting, also makes the energy consumption of processed in units amount be reduced to extremely low degree, also simplify beneficiation flowsheet simultaneously.
Of the present invention, it is as follows that the throwing tail of material sorts process:
The outside surface of permanent magnetism roller has been divided into three different regions by combination magnetic system, is respectively: the magnetized area, the Pao Wei district being positioned at roller side that are positioned at roller top and be positioned at the selected district bottom roller. Along with the rotation of outer cylinder, material is entrained into the Pao Wei district being positioned at roller side. Magnetic-particle in material is adsorbed on roller surface by the magnetic field that Pao Wei district is powerful, and continues to bring the selected district being positioned at bottom roller into along with the rotation of outer cylinder; Non magnetic gangue particle then departs from roller surface under the gravity of self and the effect of Cylinder Centrifuge power, falls into mine tailing mouth. Owing to the magneticstrength in selected district wants much weak relative to Pao Wei district, the adsorptive power of magnetic-particle is also wanted much weak by magnetic field. Enter the magnetic material in selected district, the more weak intergrowth particle of part magnetic can be thrown off roller surface and fall into mine mouth under the effect of self gravitation and centrifugal force, the higher-grade concentrate particle that magnetic is stronger be then still adsorbed on roller surface under the influence of a magnetic field and finally along with the rotation of cylinder is brought into concentrate mouth.
The foregoing is only the better embodiment of the present invention, not in order to limit the present invention, all any amendment, equivalent replacement and improvement etc. done within the spirit and principles in the present invention, all should be included within protection scope of the present invention.
