Introduction of Magnetic Separator:
Magnetic separator is for particle size below 3mm magnetite, pyrrhotite, roasted ore, ilmenite and other materials wet magnetic separation, also for coal, non-metallic minerals, building materials and other materials de-ironing. Magnetic separator magnetic system, using high quality rare earth magnets or ferrite material composite, average magnetic flux density of tube surface is 100 ~ 600mT. According to user needs, we can provide a variety of downstream, semi- reflux and reflux products with different magnetic flux density surface. This product has characteristics of simple structure, large capacity, easy to operate and easy to maintain.
Performance Features of Magnetic Separator:
1. For depleted iron ore roughing after coarse/medium crushing, can exclude waste rock to improve ore quality and reduce load for next process.
2. For hematite in a closed reduction roasting operation, select out raw ore that is not fully restored, return it and then burn again.
3. For the ceramic industry, remove mixed iron from porcelain mud to improve the quality of ceramic products.
4. For burning coal, foundry sand, refractory and other industries requires iron removal.
Work Principle of Magnetic Separator:
The ore slurry flows into the tank via feed chute, under the effect of the water flow from ore-feeding water pipe, mineral particles in loose state goes into the feeding area of tank. Under the action of the magnetic field, the magnetic mineral particles gather together to form a "magnetic group" or "flux", in the pulp "magnetic group" or "flux" goes to magnetic pole by the magnetic force, and is adsorbed on the cylinder.
Because the magnetic poles are alternately arranged along the direction of cylinder rotation, and are fixed while working, when the "magnetic group" or "flux" rotates with cylinder, the magnetic stirring phenomenon generated due to magnetic poles alternating, gangue minerals and other non-magnetic mineral existing in the "magnetic group" or "flux" fall down while rolling, eventually the "magnetic group" or "flux" being sucked in the cylinder surface is the concentrate.
The concentrate rotates with cylinder to the magnetic system edge that has the weakest magnetic force, discharged into concentrate tank under the action of flushing water from ore-discharging water pipe. If it is full-magnetic roller, ore discharging is carried out by brush roll. Non-magnetic or weakly magnetic minerals are left with the pulp discharged outside the tank, which are tailings.
