Remove iron from lithium iron phosphate

The preparation of artificial graphite needs to go through "crushing, granulation, graphitization, PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC screening" four big processes and many small processes, which granulation and graphitization two links have high technical barriers, not simply sintering can be. The following is from the raw materials of artificial graphite to start:

PTMS magnetic separator

The aggregate of artificial graphite is divided into three categories: coal measure, petroleum system and coal and petroleum mixture system. Among them, coal measures needle coke, petroleum needle coke and petroleum coke are the most widely used, in terms of the current market, PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC processing high-end negative electrode using needle coke as raw material, low and medium negative electrode using cheap petroleum coke as raw material; Asphalt acts as a binder to bond different particles together.

what is magnetic separation in science?

High-end anode manufacturers of artificial graphite production process, the first is the pretreatment process, according to the needs of the product, graphite raw materials and asphalt mixed in different proportions, and then air grinding, grinding raw materials into the granulation process, among which, Granulation process is divided into pyrolysis and PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC screening process, granulation size, distribution, morphology and so on will directly affect the performance of the negative material,
