Magnetic Separator 

Magnetic separator is suitable for the wet magnetic separation of the materials whose granularity is below 3mm such as magnetite, pyrrhonist, claimed ore and limonite and can also be used for removing iron from the materials such as coal, non-metal ore and building material. The magnetic system of magnetic separator is a compound of fine ferrite material and rare earth magnets and the average magnetic induction intensity of the surface of the cylinder is 100~600mT. According to specific need, customers can choose from many kinds of magnetic separators with different surface magnetic intensity such as downstream type, semi-reflux type and reflux-type. This product has the advantages of simple structure, big processing capacity, convenient operation and easy maintenance.

Description:

Magnetic separator is characterized by a turbulent magnetic field and high separation factor, advanced structure, light weight, reliable operation and convenient maintenance. It is often used for industrial purposes such as recycling and manufacturing. They are also found in scientific laboratories requiring metallic materials that are free of impurities (often the case in chemistry). In this case, the magnetic separator is usually a cylinder or flask that prevents cross-contamination between two different substances by forcing either all or some of the magnetic materials from one substance into a separate container.

Application of magnetic separator:

1.Magnetic separator suit for particle size below 3mm magnetite, pyrrhotite, roasted ore, ilmenite and other materials wet magnetic separation, but also suit for coal, non-metallic minerals, building materials and other materials in addition to iron work.

2.Wet magnetic separator is one kind of efficient equipment for processing fine, feebly magnetic minerals, such as hematite, limonite, wolfram, ilmenite, and tantalum-niobium, etc. In recent years, it is also more and more applied in purifying quartz, feldspar and nephline. Its magnetic system is a ring-shape chain closed magnetic circuit with energizing coils made of copper tube and cooled internally by water. Grooved plates made of magnetic conductive stainless steel are used as magnetic matrix.

Advantages of magnetic separator:

1. Improve mineral grade, reduce process under load.

2. Be able to sort the fine ore and return the inferior for re-burning.

3. Remove impurities, thus improving the quality.

4. Applicable in a wide range of industries.

Working principle of magnetic separator:

The mineral slurry flows into the cell through box feeder, the mineral particle is loose under the function of water flow of feeder water pipe when they flow into the cell. Affected by magnetic field, the 

magnetic particle swarm together and form magnetic cluster or chain. With the magnetism of mineral slurry, the magnetic cluster or chain moves toward the magnetic pole, and is absorbed to the cylinder. Because of the polarity of magnetic pole, the revolving directions alternate constantly, and remain fixed when it is working. When the magnetic cluster and chain go round and round along with the cylinder, the mingled gangue and other non-magnetic ore fall down due to the mixing phenomena produced by alternation of magnetic poles, and it is concentrate that is absorbed to the cylinder surface. The concentrate moves to the end of magnetic system where the magnetism is weakest along with the revolving cylinder, and is discharged into concentrate tank by the current ejected by the discharging-ore pipe. The non-magnetic or weak magnetic remained are discharged along with the mineral slurry, and they are gangue.
