Application: The wet magnetic separator is designed for the magnetic minerals rinsing and purification. According to the technical requirements, the concentrate can be rinsed, thickened and deslimed to improve its grade. It's used to separate and deslime for overflow product of classification after first grinding, pulp thickening before the second grinding and filtering, the magnetic mineral's desliming before feeding into the fine screen and reverse flotation, the final concentration of magnetite.
Working Principles: After being fed into the feed box, the pulp can be fed into separation area directly. The magnetic mineral is absorbed on the surface of the magnetic drum after magnetization and transferred to mineral unloading area forehead by the rotative separation drum. It can be deslimed under the washing water pushing, and the mineral is discharged into the concentrate box by the washing water or scraper. Here it's the concentrate. Meanwhile, the nonmagnetic mineral in pulp flows into the bottom box with the pulp. Due to the particles' differences in size and density in the bottom box, it can make the heavy and coarse particles sink to the bottom and out from the tailing mouth. Here it's the coarse tailing. The light slime can be discharged by the overflow devices.
Patent technological innovation points in China: 1.Concentrated magnetic separator is equipment with multipoint feeding flange in the feeder box. Open top design can achieve side and top feeding. There is overflow weir in the feeding box, which makes the materials in tank are uniform in the direction of drum length. 2.The magnetic field strength and depth of the drum surface can be adjusted by adjusting the magnetic system structure according to the material properties and separation targets, which makes the magnetic materials in tailings in less than 0.5% compared with common magnetic separators. 3.According to the separation target, the magnetic system is divisionally designed to enhance the magnetic strength in scavenging area. While the concentration area adopts multi-pole structure to reduce magnetic materials in tailing and improve the recovery and concentrate grade. 4.Magnetic system wrap angle is 160°larger than 127°of the normally downstream type. The magnetic separation area is lengthened and the rolling time of magnetic materials is increased. So the concentrate grade is improved.
