Magnetic Separators Potential Devices In Industry

Magnetic Separators are devices that use magnetic force to segregate ferrous contents and other magnetic impurities from different types of materials. Magnetic Separators are widely used in a number of industries to separate ferrous objects from the products. During the extraction of iron from the ores such as hematite and limonite, high intensity Magnetic Separators are employed to separate iron from the non-magnetic contents.

Range Of Magnetic Separators:
There is a wide range of Magnetic Separators that includes:
·    Overband Magnetic Separators
·    Concentrator Magnetic Separators
·    Plate Magnets
·    Hump Magnets
·    Suspension Magnets
·    Magnetic Grids
·    Magnetic Drum Separators
·    Magnetic Pulleys

Working Of Magnetic Separators:
Magnetic Separators comprises high intensity magnets. These devices have a simple construction as well as operation. A Magnetic Separator consists of a hopper, a feeder, a rotating drum, an enclosure, splitters, a geared motor and outlets. The mixture from which ferrous content is to be separated is fed through the hopper into the Magnetic Separator. The high intensity magnets attract the magnetic content while the non-magnetic content is discharged from the outlet and forms a separate heap. 

Applications:
Apart from mining industry, Magnetic Separators find application in various other industries. Magnetic separators are predominantly used in purifying various materials by removing the harmful magnetic impurities present in them. For this very purpose, Magnetic Separators are a necessary requirement in thermal power stations, fertilizers, plastic, chemicals, recycling and cement industry.

Besides, Magnetic Separators are used in food industry, paper production industry and manufacturing sector. Further, Magnetic Separators are also used in various laboratories for research and development purposes. The Magnetic Separators are very effective in separating all kind of magnetic impurities irrespective of the size. However, for heavier magnetic content, the Magnetic Separator should have high intensity magnets to attract them.

Desired Properties:
For efficient functioning, a Magnetic Separator should:
·    Be sturdy
·    Be resistant to temperature variations
·    Be corrosion resistant
·    Have high intensity magnets
·    Be dimensionally accurate

Magnetic Separators are a prerequisite for a large number of industrial processes. Care should be taken for their maintenance as well. Since Magnetic Separators are prone to surface wear and tear, they should be periodically lubricated with oil or grease. This ensures their longer life and high performance.
