High Gradient Magnetic Separator

What is High Gradient Magnetic Separator?

High gradient magnetic separator is a new type of strong magnetic separator developed on the basis of general strong magnetic separator, whose magnetic system is usually made of high-quality ferrite material or composite with rare earth magnets, which is mainly used for the screening of weak magnetic minerals.

High gradient magnetic separator is based on the magnetic field force to separate the magnetic material from the material. The equipment mainly consists of magnetic field system, transmission system and control system. The magnetic field system includes magnets, coils and magnetic field media, which are used to generate the magnetic field; the conveyor system includes conveyor belts and traction motors, which are used to pass the materials through the magnetic field area; and the control system is used to control the operation of the equipment and to adjust the magnetic field strength.

If you are a beginner and do not know about High Gradient Magnetic Separator, tell us your raw material characteristics, finished product requirements, site conditions, production budget, hourly production, and other requirements, we have professional engineers to equip you with a suitable model at a reasonable price. Next, let’s see the types of High Gradient Magnetic Separator we can supply.

What Is High Gradient Magnetic Separator Used For?

High gradient magnetic separator is suitable for wet sorting and magnetic separation of fine-grained weakly magnetic minerals around -200 mesh, and it can also be used for magnetic separation of non-metallic ores to remove iron and purification operations. Such as:
◇ Ferrous metals: recovery of pseudohematite, hematite, limonite, rhodochrosite, manganese ore, and so on.
◇ Non-ferrous metals: separation of wolframite, garnet and other minerals.
◇ Rare metals: recovery of tantalum-niobium iron ore, iron-lithium mica, monazite, yttrium phosphorite and other ores, etc.
◇ Non-metals: purification and removal of quartz, feldspar, kaolin, and refractory materials.

Working Principle of High Gradient Magnetic Separator

In the work of high gradient magnetic separator, after the ore slurry flows into the tank body through the feed box, the ore particles are in a loose state and enter the feed zone of the tank body under the action of the water flow from the feed spray pipe. Under the action of the magnetic field, the magnetic ore particles undergo magnetic aggregation and form “magnetic clusters” or “magnetic chains”. “Magnetic clusters” or ‘magnetic chains’ in the slurry by the magnetic force, to the magnetic pole of the movement, is interspersed in which the vein stones and other non-magnetic minerals in the flopping off. Ultimately sucked in the cylinder surface of the “magnetic mass” or “magnetic chain” is the concentrate, concentrate with the cylinder to the edge of the magnetic system of the weakest magnetic force, in the unloading water pipe under the action of the flushing water flow is unloaded into the concentrate tank, non-magnetic or weakly magnetic minerals are left in the slurry along with the slurry The non-magnetic or weakly magnetic minerals are left in the slurry and discharged with the slurry to become tailings.

Advantageous features of High Gradient Magnetic Separator

• Wide range of application: due to the unique magnetic system structure and optimized combination of magnetic media, the upper limit of the feed size of the high gradient magnetic separator reaches 2.0 mm, which simplifies the on-site grading operation and has wider adaptability.
• High gradient magnetic field: Setting up the slurry high frequency vibration mechanism, driving the slurry to generate pulsating fluid force, so that the ore particles in the slurry are always in a loose state, which can improve the quality of magnetic concentrate.
• Good adaptability to the nature of the material: it has strong adaptability to the fluctuation of the feeding particle size, concentration and grade, and is able to deal with ores and slurries of different natures.
• High production efficiency: the use of wrapped open magnetic system, the material is not wrapped, no blocking phenomenon, while the use of magnetic field strength and gradient of the minerals in one stage of separation, separation of minerals process is more simple, improve the processing capacity and mineral recovery rate.
• Overall superior performance: the equipment runs smoothly, works reliably, and has strong adaptability to the fluctuation of the feeding degree, concentration and grade of the materials.
