Different sequence of iron removal process can achieve multistage PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC iron removal. First, dry iron removal, using the magnetic field to directly remove the iron impurities in the dry material adsorption, and then wet iron removal. Some iron removal machines are also equipped with a blowing device, wet iron removal is the material after the dry iron removal made into slurry, in the liquid environment using magnetic separation equipment to remove iron.
Wet iron removal can further remove some iron impurities that have not been completely removed in the dry iron removal due to the surface wrapping and other reasons, because in the liquid environment, the material is better dispersed, and the iron impurities are more likely to be captured by the magnetic separation equipment. After removing the graphite PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC from iron, the fan is opened, so that the nozzle blows the inside of the first iron removal device, and the graphite remaining on the hopper is blown away to reduce the graphite residue on the hopper.
In the production of graphite cathode material, the first dry PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC iron removal is used to remove most of the free iron impurities, and then the graphite material is made into slurry for wet iron removal, which can effectively improve the purity of graphite material and reduce the influence of iron impurities on the properties of graphite.
