Natural graphite anode is prepared by a series of modification treatments such as spheroidization, purification, coating and carbonization of flake graphite, and has extremely high cost-effectiveness. At present, natural graphite is mainly used in 3C and small electronic products. However, with global anode material companies and battery manufacturers investing more in the research and development of natural graphite anode, the proportion of natural graphite anode in the power battery market is also constantly increasing.
ZDZN could provide one-top solution of natural graphite anode, which include grinding & shaping system, purification system , granulation system, high temperature carbonization system, final product handling and packing system.
After grinding, the raw materials turned into 5-75μm ultra-fine powder and our shaping mill is specially designed for anode material, which is use for material surface modification, to improving the tap density.
Most natural graphite has a high degree of smoothness and has been spheroidized, but there are still a few that need to be granulatedand the electrical heating device will provide staged heating to help the mixed materials coated.
The purification of natural graphite generally requires chemical acid washing and purification.
High temperature carbonization after the graphitization process can remove impurities and improve product quality. The maximum temperature can reach 1200℃.
The Final Product Handling System, which include feeding, screening, mixing, demagnetization, packagingsystem.After processing, it can ensure the stability of different batches of materials and remove magnetic substances and impurities.
