Abstract

A method for separation of magnetic material features that the magnetic material to be separated is magnetized in magnetic field as uniform as possible to form magnetic material chains parallel to magnetic force lines and unmagnetized granular impurities are removed by sieves parallel to magnetic force lines. Its advantages include the ability to remove coenobium impurities in magnetic product and wide range of material granularities.

Description

Magnetic field screening method and equipment thereof
The present invention is a kind of sorting enrichment method and facilities and equipments thereof of magnetic thing.
Present widely used magnetic selection method all is by the direct attraction capture magnetic thing of magnetic field force in the non-uniform magnetic-field to the magnetic thing.The characteristics of this method are magnetic thing rate of recovery height, but are mingled with nonmagnetics in the magnetic product easily, and more difficult removing is the intergrowth of magnetic thing and nonmagnetics wherein.In order to overcome the shortcoming of single magnetic selection method, with the immediate method of the present invention be the applicant in the patent of invention of utilizing magnetic agglomeration gravity separation method " magnetic agglomeration gravity separation separator " of application on May 10th, 1985 (patent No.: 851034578, February 24 1988 day for announcing).This method is in the low-intensity magnetic field of disperseing, and reunites accelerating its gravitational settling speed in medium by the magnetic solid magnetizing, and carry out sorting with the non magnetic and weak magnetic thing (be mainly and contain magnetic thing intergrowth) that disperses in shearing ascending current.It can from selected material, remove very effectively sinking speed less than magnetic aggressiveness sinking speed than fine fraction impurity, but for this then still can not get rid of more than the sorting boundary line than coarse fraction impurity.
The objective of the invention is will be when utilizing faint uniform magnetic field to carry out the sorting of magnetic thing, manage to eliminate ascending water speed to can the despumation granule size restriction, thereby but enlarge the scope of size range of separation in the selected material, further improve the efficiency of separation.
Method of the present invention is:
1, at first in the magnetic field that as far as possible evenly is provided with, will be selected in the magnetic solid magnetizing and become chain magnetic aggressiveness;
2, meanwhile unmagnetized dispersion impurity particle is screened out with the sieve that is arranged in the magnetic field.
The equipment that designs for enforcement the inventive method is: the sorting sieve is arranged between the two equifield intensity opposite poles, compass screen surface is parallel to the magnetic line of force that forms between two magnetic poles as far as possible, screen-aperture or sieve seam width want to allow that maximum individual particle freely sieved in the sieve material, lowest magnetic field on the compass screen surface is wanted to make into the magnetization of sieve magnetic-particle and is connected into the chain magnetic aggressiveness of length greater than screen-aperture or sieve seam width, makes it to be difficult to sieve.
The present invention can with liquid (generally being water), also can be with gas (generally being air) as separating medium; The multi-disc compass screen surface screen banks can be connected between a plurality of magnetic poles, also the multi-disc compass screen surface screen banks can be overlapped between two magnetic poles.
The invention has the beneficial effects as follows: adopt this method and equipment thereof, even the chain magnetic aggressiveness that faint magnetization forms, its chain length also is easy to surpass the manyfold that maximum individual particle in the sieve material is put the footpath, be far longer than the difference of above-mentioned same magnetic aggressiveness and individual particle gangue sinking speed, so can further improve the efficiency of separation than the wideer material of the effective sorting particle size range of magnetic agglomeration gravity separation method.
Accompanying drawing 1: the oblique magnetic field screening installation part schematic diagram that compass screen surface is set.
Accompanying drawing 2: the magnetic field screening installation part schematic diagram that compass screen surface vertically is set.
Realize that best way of the present invention is as follows:
As shown in Figure 1: material is fed by feed port 1, become chain magnetic aggressiveness when sinking, to be stopped by magnetic pole 2 magnetized magnetic things and, can not fall into tail-box 5 by magnetized dispersion individual particle big sieve aperture of tranmittance particle size when sinking along slipping into concentrate hopper 4 under the compass screen surface by compass screen surface 3.
As shown in Figure 2: material is fed by feed port 1, do not flowed out from tail-box 5 with the big sieve aperture of MEDIA FLOW tranmittance particle size by magnetic pole 2 magnetized dispersion individual particles, the magnetic thing that is magnetized becomes chain magnetic aggressiveness to be stopped by compass screen surface 3 and is lowered into concentrate hopper 4 along compass screen surface.

Claims (6)

1, a kind of sorting enrichment method of magnetic thing is characterized in that: will be selected in the magnetic solid magnetizing and become chain magnetic aggressiveness in the magnetic field that as far as possible evenly is provided with, and with the sieve that is arranged in the magnetic field unmagnetized dispersion impurity particle be screened out simultaneously.
2, a kind ofly execute the screening installation that the real power profit requires 1 method, it is characterized in that: sieve is located between the two equifield intensity opposite poles, and compass screen surface is parallel to the magnetic line of force that forms between two magnetic poles as far as possible.
3, screening installation according to claim 2 is characterized in that: a plurality of compass screen surfaces laterally are connected into screen banks between a plurality of magnetic poles.
4, according to claim 2 or 3 described screening installations, it is characterized in that: a plurality of compass screen surfaces are overlapped into screen banks between two magnetic poles.
5, method according to claim 1 and 2 or equipment is characterized in that: separating medium is liquid (wet type).
6, method according to claim 1 and 2 or equipment is characterized in that: separating medium is gas (dry type).
