To choose iron from sand is one of the hot industries at the moment. And to separate iron from sand cannot do without magnetic separator. The most common used magnetic separator is electromagnetic separator.

Magnetic separator is one of the most widely used machines in this industrial circle, which is used in remove of iron powder in the reutilization of powder. Magnetic separator is widely applicated in the resource recycling, lumbering, mining industry, ceramic industry, chemistry, foodstuff and etc. it is suitable for the wet magnetic separation of materials with the granularity under 3mm such as magnetite, pyrrhotite, calcined ore, ilmenite and etc, as well as in the remove iron work of coal, nonmetallic ore, building materials and etc. magnetic system of magnetic separator combines with high quality ferrite materials and rare earth magnetic steel. In the past, Average magnetic induction of drum surface is about 800-4000. As the technology advance, magnetic separator can be made in the shape of roller, and then the magnetic induction can reach 8000mt, it is the highest actual measured magnetic field intensity at present.

According to types of magnet, magnetic separator can be classified as permanent magnetic separator and Electromagnetic separator; according to ore’s wet and dry types, it can be divided as wet type separator and dry type separator; according to magnetic system, it can be divided as drum separator, roller separator and drum roller; according to quantities of magnetic systems, it can be divided into single drum magnetic separator, double drum magnetic separator and combined multi-drum magnetic separator; according to feeding ways, it can be classified as upper feeding magnetic separator and lower feeding magnetic separator, according to magnetic field intensity, it has the types of weak magnetic separator, medium magnetic separator and strong magnetic separator; according to classification of magnetic system, it can be divided into Open magnetic circuit magnetic separator, closed magnetic circuit magnetic separator.
