Magnetic separator

Introduction of Magnetic Separator

Magnetic separators are often used for industrial purposes such as recycling and manufacturing. They are also found in scientific laboratories that often require 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

The wet magnetic separator can separate raw materials with different magnetic rigidities. The machine works under the magnetic force and machine force. Magnetic separators are designed to recover ferromagnetic materials. The magnetic drum separators are available in designs and sizes to provide solutions for all applications. The heart of each separator is the magnetic system with its unique design and a  proven record of high efficiency. China magnetic separator is available in cyclic design with process vessel diameters smaller than 3mm. Magnetic separator is one kind of efficient equipment for processing fine and feeble magnetic minerals, such as hematite, limonite, wolfram, ilmenite, and tantalum-niobium, etc.

Advantages of Magnetic Separator:

1) Short magnetic circuit;

2) Little magnetic flux leakage;

3) High magnetic intensity;

4) Low energy consumption;

5) Fine beneficiating results;

6) Simple structure and easy to maintain.

Working Principle

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.
