As a result of the studies, as an alternative to magnetic separators; different imitation magnetic separators have been developed, including low field strength, high field strength, dry and wet.
The main magnetic separators used in industry are;
- Krupp Left,
- Metso Cyclic,
- Cryofilt is,
As an alternative to the above-mentioned separators, imitation magnetic separators can be grouped under 4 main headings.
Low Field Intensive Dry Magnetic Separators;
On-belt magnets, belt-type and drum-type separators can be specified under this heading. Low field strength dry magnetic separators are used for protection and removal of minerals with high magnetic susceptibility from diamagnetic particles. Magnetic field intensities are between 500-5000 Gauss.
Low Area Severe Wet Magnetic Separators;
The most common use is drum type separators, low-field intense wet magnetic separators are used in the enrichment of fine grains. In the production of such separators, fixed or electromagnets are preferred.
High Field Intensive Dry Magnetic Separators;
Electromagnetic magnets are used in dry magnetic separators with high field strengths with magnetic field strength of around 18000 Gauss. The disadvantage of separators is that they have to consume high electricity in order to produce high field strength. Another disadvantage is that it cannot separate very small particles.
High Field Heavy Wet Magnetic Separators;
Magnetic field intensities one of the most striking features of high field intense wet magnetic separators, which can reach up to 24000 Gauss, is that they also have a high gradient. They are produced in two different ways as carocell and reservoir. It is possible to make micron size separations with these separators.
In addition to these four basic separators, superconducting magnetic separators have been produced. These separators conduct electrical current without any resistance. It is not possible to conduct the electric current without any resistance at room temperature. Therefore, a temperature of -273 ° C or less is required to activate these separators, which is not easy as you think. Therefore, the use of superconducting magnetic separators is not very common in the sectors.
