Magnetic Separator
Magnetic separator is widely used for separation of wet and strong magnetic minerals. The magnetic system adopted is made of high magnetic-energy and high-coercivity NdFeB magnet, which contributes to high magnetic field intensity and large effective depth. Demagnetization rate of the magnetic filed in 8 years is less than 5%. With a large wrap angle, the magnetic system ensures gradient increase and smooth transition of filed intensity. It enlarges the length of separation zone and enhances magnetic turning efficiency. Therefore, magnetic minerals can be efficiently separated from weak magnetic or non-magnetic minerals. The magnetic system is wrapped with a kind of material which is un-conductive magnetic and stainless, thereby efficiently preventing the magnet from falling off. The separator barrel is also un-conductive magnetic and stainless and it is also coated with corrosion-resistant rubber. Consequently, the service time of the barrel is extended.
Generally, the cell body is semi-countercurrent type. However, we still provide concurrent cell body if required. Both the magnetic system and the cell body can be customized according to customers’ requirements. Our magnetic separator is applicable for different environment. It is able to work normally even when ore quantity, feed size or pulp density changes significantly.
Based on the foundation structure, magnetic separator can be divided into concurrent type, countercurrent type and semi-countercurrent type.
