The high gradient magnetic separator equipment is suitable for the mining of weak magnetic minerals, such as hematite, limonite, siderite, ilmenite, chromite, wolframite, antimony ore, red mud and so on. Iron removal and purification of non-metallic minerals. For example: quartz, feldspar, nepheline, fluorite, sillimanite, spodumene, kaolin, etc. The high gradient magnetic separator is suitable for wet magnetic separation of magnetite, pyrrhotite, roasting ore, ilmenite and other materials with a particle size of 3mm or less. It is also used for iron removal of coal, non-metallic minerals, building materials and other materials.
The high gradient magnetic separator is a kind of equipment specially designed for weak magnetic ore beneficiation. It is divided into two types: dry selection magnetic machine and water selection magnetic machine. The general weak magnetic ore mainly includes limonite, hematite, manganese ore and symbiotic ore. (Multiple mines coexist), this weak magnetic ore is mainly composed of ferric oxide. In order to extract the ferric oxide, it needs to be sorted by high-strength magnetic equipment.
There are many weak magnetic ores that are massive and need to be crushed first, ball milled and then magnetically selected. The general experiment is divided into analysis of minerality, E-break, screening, roll-to-roll, grinding and magnetic separation, depending on the nature of each mine. Find out the best experimental method to achieve the purpose of mineral processing.
Any mineral is not a monomer. Generally, the weak magnetic ore contains some mechanical iron (ferric oxide), and other substances (such as sulfur, silicon, etc.). The magnetic field strength of this high-strength magnetic concentrator can reach 1,200-16,000 Gauss. If the mechanical iron in the ore is not selected, the mechanical iron will affect the beneficiation effect of the high-strength magnetic concentrator in the actual beneficiation work. The mechanical iron sticking on the strong magnetic roller will affect the magnetic field of the strong magnetic machine, so that the magnetic field reaches The concentrate should not be allowed to flow into the tailings pond, so the existing mechanical iron should be selected before the selection of ferric oxide.
The high-gradient magnetic separator adopts a rotating ring vertical rotation and recoil concentrate, and is equipped with a high-frequency vibration mechanism.
It fundamentally solves the worldwide technical problem that the magnetic material of the flat ring strong magnetic separator and the flat ring high gradient magnetic separator are easy to block.
During the work, after the slurry is fed into the tank by the ore tank, the ore particles are loosely fed into the feeding area of the tank body under the action of the water flow to the mine sprinkler pipe. Under the action of the magnetic field, the magnetic ore particles are magnetically aggregated to form a "magnet" or "magnetic flux". The "magnet" or "magnetic flux" is subjected to magnetic force in the slurry, moving toward the magnetic pole, and being adsorbed in the cylinder. on. Since the polarities of the magnetic poles are alternately arranged in the direction of rotation of the cylinder, and are fixed during operation, the "magnet" or "magnetic flux" is magnetically agitated due to the alternating magnetic poles when being rotated with the cylinder, and is mixed. The non-magnetic minerals such as gangue in the "magnet" or "magnetic flux" fall off during the flipping, and the "magnet" or "magnetic flux" that is finally attracted to the surface of the cylinder is the concentrate. The concentrate goes to the weakest point of the magnetic system at the edge of the magnetic system with the cylinder, and is discharged into the concentrate tank under the action of the flushing water sprayed from the unloading water pipe. Non-magnetic or weakly magnetic minerals are left in the slurry with the slurry exiting the trough, which is the tailings.
Scope of application:
1. Black metal: recovery of hematite, limonite, siderite, chromite, ilmenite, manganese ore;
2. Non-ferrous metals: recovery of fine-grained black tungsten ore in tungsten-containing quartz veins, separation of pyrrhotite in cassiterite polymetallic sulfide ore, separation of cassiterite from black tungsten ore, minerals such as limonite Separation, separation of scheelite from minerals such as wolframite and garnet;
3. Rare metal: recovery of coltan, iron-lithium mica, monazite, etc.
4, non-metal aspects: glass ceramic industry raw materials quartz, feldspar, kaolin purification, high temperature refractory sillimanite, andalusite, kyanite de-ironing and removal of hornblende, mica, tourmaline, garnet, etc. Impurities, etc.
5. Other aspects: weak magnetic tailings recovery; alumina plant hematite mud selection; wastewater treatment in steel plants and power plants; cleaning of chemical raw materials contaminated by catalysts.
Performance feature editing
The utility model has the advantages of large enrichment ratio, strong adaptability to the feeding material concentration, concentration and product fluctuation, reliable work, convenient operation and maintenance, and the like.
The magnetic system of the high gradient magnetic separator is made of high quality ferrite material or composited with rare earth magnetic steel. The average magnetic induction intensity of the magnetic roller surface is 100-600 mT. According to the needs of users, it can provide magnetic separation of many different surface strengths such as downstream, semi-reverse flow and counterflow.
During the operation of the high gradient magnetic separator, for each group of magnetic media, the direction of the rinse concentrate is opposite to that of the ore supply, and the coarse particles can be washed out without passing through the magnetic medium stack, thereby effectively preventing the magnetic medium. Blockage; set the high frequency vibration mechanism of the slurry to drive the slurry to generate pulsating fluid force.
