Abstract
The utility model relates to a multi-magnetic pole, low field strength permanent-magnet drum magnetic separator which belongs to an ore separating device. The complete machine comprises a machine frame, a rolling drum, an ore feeding box, a concentrate tank, a bottom box, a permanent magnetic system, etc. The utility model is characterized in that when the diameter of the rolling drum is within the range of 1000-1500 mm, the permanent magnetic system is composed of 7-20 magnetic poles, the magnetic field strength on the surface of the rolling drum, on which magnetic poles are arranged, is distributed in a step ladder shape, and the magnetic fieldstrength is smaller than 87.56 kilo amperes/ metre. As a result, the utility model can make the ore under the action of the magnetic field generate strong magnetic rolling more frequent than a magnetic separator with the traditional structure to realize the reasonable match of the ore separating recovery rate and the concentrate grade.
Description
Many magnetic poles, low field intensity permanent-magnet drum type magnetic separator that the utility model relates to belong to preparation equipment.
For many years, in the magnetic dressing technical field, people are devoted to how to improve the magnetic field intensity of the permanent magnetic separator section of sorting always, make valuable mineral recovering effect as much as possible in the hope of reaching---be the more satisfactory rate of recovery, but find in practice, the separation of some mineral is not that magnetic field intensity is high more good more.For example: the separation of more typical vanadium titano-magnetite, though high magnetic field intensity can improve the rate of recovery, also cause concentrate grade to descend, thereby in the further smelting of concentrate, cause energy consumption to rise, influence economic benefit.Its cylinder barrel dliameter of drum magnetic separator in the known technology general number of magnetic poles that adopts in φ 1000～1500mm scope be 6 extremely below, and magnetic field intensity is mostly in 87.56 kilo-amperes/more than the rice, and the magnetic of technical parameter system is provided with and can not reaches desirable separating effect to some mineral like this.
The utility model purpose is to provide a kind of many magnetic poles, low field intensity permanent-magnet drum type magnetic separator, reduce the technological means of magnetic field intensity simultaneously by setting up number of magnetic poles, to barrel dliameter is that the permanent magnetic system of the drum magnetic separator of φ 1000～1500mm improves design, makes every effort to make recovery rate in ore-dressing and these two indexs of concentrate grade that the reasonable matching value of a desirable economy is arranged.
The technical scheme that adopts that achieves the above object is: this many magnetic poles, low field intensity permanent-magnet drum type magnetic separator comprise frame (1), cylinder (2), give the permanent magnetic system of establishing in ore deposit case (3), concentrate hopper (4), under casing (5) and the cylinder (2), it is characterized in that: at the barrel dliameter of cylinder (2) is that said permanent magnetic system is made of 7～20 magnetic poles in φ 1000～1500mm scope the time; In the stepped distribution of cylinder surface corresponding site magnetic field intensity that magnetic pole is set and magnetic field intensity less than 87.56 kilo-ampere/rice.
Fig. 1 is these many magnetic poles, low field intensity permanent-magnet drum type magnetic separator organigram.
Fig. 2 is Fig. 1 intermediate roll and permanent magnetic system arrangement schematic diagram.
Fig. 3 is a permanent magnetic system pole configuration schematic diagram among Fig. 2.
Fig. 4 is the organigram of each magnetic pole among Fig. 3.
The embodiment that provides below in conjunction with accompanying drawing further describes.Include the permanent magnetic system that is provided with in frame (1), cylinder (2), the transmission system of giving ore deposit case (3), concentrate hopper (4), under casing (5) and cylinder (2) and the cylinder (2) referring to shown in Figure 1 magnetic separator, these all belong to the known technology category, pardon not superfluous stating.Substantive distinguishing features of the present utility model only is the improvement design of permanent magnetic system shown in Figure 2 (6), it comprises two essentiality contents, barrel dliameter at cylinder (2) is under the preceding topic of φ 1000～1500mm, one is that permanent magnetic system (6) shown in Figure 2 is in a scope, the magnetic field intensity of this permanent magnetic system (6) is less than 87.56 kilo-ampere/rice, generally between 39.8～87.56 kilo-ampere/rice; Another be shown in Figure 3 be that permanent magnetic system (6) is made of 7 magnetic poles (7) in a scope at least, general magnetic pole number is between 7～20, each magnetic pole (7) is alternately arranged along cylinder (2) cylindrical shell circumferencial direction, make the drum surface corresponding site magnetic field intensity that magnetic pole is set be ladder (increasing or decreasing) distributions, and its field strength values in a scope less than 87.56 kilo-ampere/rice.For realizing above-mentioned two substantive distinguishing features, then should be less than 130mm in the b scope value of as shown in Figure 4 each single magnetic pole (7), magnetic pole (7) can adopt as permanent-magnet materials such as strontium, barium ferrite, neodymium iron boron, samarium praseodymium cobalts and make.
The magnetic system design of this permanent-magnet drum type magnetic separator is under the preceding topic of φ 1000～1500mm scope at the cylinder barrel dliameter, the structural parameters of many magnetic poles (7～20 magnetic poles) and low field intensity (39.8～87.56 kilo-ampere/rice) have been adopted, make selected mineral in such active region, magnetic field, cause the strong magnetic rolling more more frequent than traditional structure parameter, make the gangue the like waste that is mixed in the valuable mineral easier by jettisoning, thereby can obtain comparatively desirable concentrate, realize the reasonable coupling of these two indexs of recovery rate in ore-dressing and concentrate grade.
