Since the development of wet magnetic separators, the development of wet magnetic separators is the most extensive. The wet magnetic separators are different from the dry magnetic separators. The wet magnetic separators are more concerned by the masses.

The working principle of the wet magnetic separator is that after the slurry enters the sub-selection, under the action of the magnetic force of the magnetic field, the ferromagnetic mineral is adsorbed on the surface of the cylinder, and is carried along the cylinder to the concentrate ore, and the water is drained by means of the concentrate. Into the concentrate tank, in general, the use of magnetic force for mineral sorting, and those gangue and weak magnetic minerals can not be magnetically attracted, in the tank slurry, the tailings. Wet magnetic separators are sorted according to different specific susceptibility.



The wet magnetic separator not only achieves the scope and recovery of concentrates, but also expands the market for magnetic separators. The new development of wet magnetic separators has evolved from a magnetic system to two magnetic systems.

1. The full ferrite magnetic system consists of low-priced barium ferrite magnets. The average magnetic induction of the cylinders is 120mT and 170mT, respectively.

2. Rare earth composite magnetic system, a small number of high-performance rare earth materials and ferrite magnetic blocks composite composition, rare earth materials used to strengthen the tailings sweeping area, the total magnetic induction intensity of the cylinder table is 200mT, the tailings sweeping enhanced area Up to 300mT, the average is still above 100mT at 50mm from the surface of the cylinder.
