Description
Technical field
The utility model belongs to the dry-type magnetic extractor field, be applicable to the sorting of industry magnetic minerals behind the milling equipment grinding such as metallurgy, mine, chemical industry, but according to material solution grain situation sorting finished product or semi-finished product, especially application diameter is less than the sorting of the pulp of 1mm.
Background technology
Utilize the difference of mineral grain magnetic, sorting in magnetic field is the method that the magnetic material sorting is adopted usually.Wet magnetic separator needs water as working media, can't use in the water-deficient area, and may cause environmental pollution, be unworthy promoting, thereby dry type magnetic separation has obtained development faster in recent years.The conventional dry magnetic separator catches the magnetic mineral particle by the direct attraction in magnetic field, but causes the mineral recovery rate that sorts not high because solid accumulation thickness, magnetic system pollute and reason such as be mingled with, and becomes the subject matter that magnetic separation faces so improve the rate of recovery of magnetic mineral.For this reason, many solutions have been proposed in the industry.
A kind of wind-suction type permanent magnetism ore concentrate machine of Chinese patent CN201220178917.7 application, comprise charging aperture, dry type magnetic separation device, tailing storehouse and feed bin, the cavity inner roof wall of described dry type magnetic separation device is obliquely installed, and at the port of export of dry type magnetic separation device air extractor is installed; In the cavity of dry type magnetic separation device, be disposed with the first magnetic roller group and the second magnetic roller group along the pan feeding direction.
A kind of oscillatory type high-performance magnetic separation machine of Chinese patent CN201220367847.X application comprises left socle, right support and conveyer belt, and left socle, right support are connected by link; Described left socle one end is provided with can be to the magnetic separation roller of magnetisable material absorption, and right support one end is provided with the driving runner that orders about the driving-belt motion, drives runner and is connected with Power Drive Unit; Described link is provided with the magnetic vibrating device that is positioned at the driving-belt below.
A kind of dry-type magnetic extractor of Chinese patent CN201210043655.8 application, comprise conveyer belt, conveyer belt is divided into feeding section and magnetic separation section, magnetic separation section inboard arranges magnetic system, the magnetic separation section is followed successively by the section of roughly selecting, selected section of circular arc and concentrate feeding section along flow direction of material, and the section of roughly selecting below correspondence arranges the inflatable shaking chute.
Suchlike solution is also a lot, does not enumerate one by one at this.Summary is got up, and solution namely adopts wind-force, vibration or mode of movement that the two has concurrently to make it fully be exposed to magnetic system down, thereby reaches the purpose that improves the magnetic mineral rate of recovery.
Compared to the conventional dry magnetic separator, above-mentioned solution makes the rate of recovery of mineral be enhanced, but still exists the undesirable problem of grade that reclaims mineral.Canvass its reason, mainly be only as a kind of carrying capacity because of the wind-force in the above-mentioned solution, magnetic material only has gravity and vibration force and magnetic force competition in the process of sorting, and the characteristic of particulate magnetic material makes the mineral that sort out exist more parcel and is mingled with, thereby causes the undesirable problem of mineral grade.
The utility model content
The purpose of this utility model is: provide a kind of and can improve the magnetic mineral rate of recovery and grade, dry-type magnetic extractor concentration equipment that sorting power is adjustable.
The utility model purpose realizes by following technical proposals:
