subject: Separating Equipment Is Of Great Importance [print this page] The magnetic separator is suitable for wet magnetic separation of materials such as magnetite, calcined ore , etc. and it can remove the iron in the coal, non-metal and construction industries. The magnetic system is made from high quality ferrite magnetic materials and /or rare earth magnet steel. On the shell surface, the magnet intensity is 100-600mt. The wet type permanent magnet cylindrical separator is commonly used for iron ore separation. It is suitable for separating materials with high magnetism. In recent years, it has been used as concentrating equipment in place of magnetic dewatering cell.
The magnetic separator is one of commonly used preparation equipments in magnetic separation factory. It has dry and wet two types. According to types of magnets, it can be divided into permanent magnet type and electromagnet type. It is also can be divided into strong magnet type, middle magnet type and weak magnet type according to the magnetic field strength. Different magnetic separators have different characteristics and performance. According to the body appearance magnetic separator is divided into belt type magnetic separator, cylindrical magnetic separator, roll type magnetic separator, disc type magnetic separator, ring type magnetic separator, cage type magnetic separator and pulley type magnetic separator.
In recent years, the successful development of weak magnetic gravity separation equipment, such as magnetic separation column, composite Flash and magnetic field screening separator machine, will be described in this paragraph. Beijing General Research Institute of mining and metallurgy researched BK series permanent magnet drum magnetic separator, including BKY, BKC, BKJ, BKW, and BKF 5 models, which respectively apply to the pre-selection, roughing, premium, flotation tailings re-election and anti-bubbles of magnetic separation.
Since the 19th century, the magnetic separation process has been used for beneficiation. In the 1970s, the more economic magnetic separator was discovered. In addition, iron ore magnetic separation is used in many mineral processing.
Over the past 10 years, magnetic separation is a less polluting or pollution-free mineral processing technology. Due to the mass production of high performance permanent magnet material ND-Fe-b and suitable price of them, they promote the research and development of new magnetic separation equipment to large extent. During this period, lump ore dry permanent magnetic separator and wet permanent cylinder type magnetic separator developed rapidly.
Owing to the permanent magnet material formation of the magnetic system has already changed from ferrite to some rare earth ND-Fe-b, which composed of composite magnetic system, or some using all of the ND-Fe-b magnetic material being composed of magnetic system, so that the technical performance of magnetic separation equipment is continuously improving.
