It can be seen from the table that the metal impurities are brought in during the preparation of ternary materials.
According to the method of generating magnetic field, it can be divided into permanent magnet iron remover, electromagnetic iron remover, superconducting iron remover and so on.
In the preparation process of ternary materials, the electromagnetic dry powder iron remover is mainly used for iron removal before the packaging of ternary materials. But the finished product of ternary material has a certain weak magnetism, so it needs to use air hammer to knock in the process of magnetic separation.
Serial number | Process section | Source of magnetic impurity |
1 | Raw materials and accessories | Nickel sulfate, cobalt sulfate, manganese sulfate, sodium hydroxide, lithium carbonate |
2 | Precursor reaction | Wear or corrosion of metal reactor and metal parts |
3 | Mixture | Abrasion or corrosion of mixing equipment |
4 | Crushing and grading | Wear of crushers and pulverizers |
5 | Material transportation | Pipe wear or corrosion |
