Artificial graphite anode material are mainly made from high quality low sulphur content petroleum coke or needle coke which are with high capacity, high compact density, high temperature storage performance and excellent cycle performance. Suitable for 3C, EV and ESS batteries. Prominer team can provide the intergrated synthetic graphite anode material plant include grinding, shaping, granulation, precarbonization, graphitization, high temperature carbonization and final product handling.
The main process flow of Artificial Graphite Anode is as follows. If you want to know more process details, please click the button below to get complete information.
We can provide different grinding mill and shaping mill to process the green coke, calcined coke and electrode fines. The main target of grinding and shaping work is for obtaining good shape coke particle size and make the particle size distribution more uniform.
Coating and granulation processing is the key step in the whole anode material processing and its performance determines the quality of final product. Our granulation system can do the coating and granulation work together. It can make the coating material and graphite mixing evenly and sufficiently and the electrical heating device will provide staged heating to help the mixed materials coated.
The function of precarbonization process is for improving the density of coke powder and improve the loading capacity of graphitization furnaces. There are two options available for precarbonization process which are tunnel furnaces and rotary kilns.
The graphitization of the anode material is that the intermediate product form precarbonization segement or the coating & granulation segment is heat-treated at a high temperature of 2800~3000 ℃, so that the disordered microcrystalline structure formed by a large number of carbon atoms is ordered, the interlayer spacing is reduced, and the lattice constant is close to natural graphite, thereby obtaining the physical and chemical properties required for artificial graphite anode materials. We can provide different type graphitization system include Acheson furnaces, LWG furnaces and Box type furnaces.
For making the natural graphite anode materials, Carbonization treatment is also the most important processing step. During the high temperature condition (Maximum 1100 degree), it make the coating material and spherical graphite fused together and the coating material formed a shell to wrapping the spherical graphite.
The anode material from carbonization furnaces will be sent to the final product handling system which include deagglomeration, mixer, magnetic separation, sieving and packing system.The mixer is for mixing the multi batch final product before packing for ensure the stable property. Dry type High magnetic separator is specialy designed for removing the mechanical iron in ultrafine powder which generated during processing.
