Background technique
Magnetic separation is the magnetic contrast using sorted material, and a kind of beneficiation method of minerals separation is made in magnetic field.Magnetic separation
Technology is widely used in the sorting of metallic ore, the purification of non-metallic ore, the recycling of secondary resource and environmental protection etc..
Magnetic separation can be divided into dry type magnetic separation and wet magnetic separation by separation operation mode difference, and dry type magnetic separation is not necessarily to that purpose mine can be realized with water
The separation of object and gangue mineral has many advantages, such as that small occupied area, water-saving, small investment, process structure are simple and at low cost,
It is particularly suitable for drought and water shortage and north cold area, while there will not be beneficiation wastewater outlet during dry type magnetic separation, it will not
Cause water pollution；But the disadvantages of that there are technical indicators is sometimes lower for dry type magnetic separation, dust environment easy to pollute and limit its
Application range.
During the actual job of magnetic separation, the magnetic separation separation of coarse-grained material (> 6mm) can generally be obtained using dry type
More satisfactory separation index；But when particulate (< 6mm) the especially material of < 0.5mm uses dry type magnetic separation, because of the ratio of material
Magnetic susceptibility is reduced to be significantly increased with coercitive, and beads magnetic substantially weakens；On the other hand, granularity attenuates electrostatic attraction and model moral
The effect of Hua Li is more obvious, and is eventually led to dry type magnetic separation separation index and is sharply declined.Effect is sorted for guarantee fine magnetic separation
Fruit, the decentralized medium that mineral are generally adopted water as in industrial production carry out wet magnetic separation, consume a large amount of water during magnetic separation, and one
As for raw ore per ton need to consume 5-7 tons of water, while sorting product and being concentrated, filtered, tailing settled,
The operations such as concentration processing, there are process flows it is long, equipment is more, capital expenditure is big the problems such as, especially certain field materials not
It can be spontaneously wet out by water, can not be handled using wet magnetic separation, to limit the application range of wet magnetic separation technique.
In recent years, since the development of magnetic material and equipment research and development new approaches emerge in large numbers, the research of dry-type magnetic selection apparatus and
Using being grown rapidly.107716099 A of Chinese patent CN discloses a kind of gas suspension dispersion belt magnetic separator, defeated
