In the production of graphite anode material for lithium ion battery, the purity requirement of graphite is extremely high, because iron impurities can seriously affect the performance of the battery. The principle of multistage iron removal has been fully applied in the PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC process. First, the dry magnetic iron removal machine is used as the primary iron removal equipment, and its magnetic field is used to remove the large particle iron impurities in the graphite raw material.
In some manufacturers, the dry magnetic separation PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC used can remove most of the iron impurities with large particle size and magnetic strength, which may be mixed in graphite mining or initial processing. Then the secondary iron removal, using the wet magnetic separation iron removal machine.
The graphite after the primary iron removal is made into slurry, and the magnetic field of wet magnetic separation PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC is used in the liquid environment. In this process, some fine iron impurities that are not completely removed in the dry iron removal due to graphite surface coating and other reasons can be effectively removed. The wet magnetic iron removal machine improves the efficiency and accuracy of iron removal by adjusting the strength of the magnetic field and the flow rate of the slurry.
