The synthetic graphite manufacturing process consists of the
following principal stages:
- Powder preparation
- Shape forming
- Baking
- Graphitization
- Pyrolytic graphite
Powder Preparation
Raw materials for synthetic graphite fabrication (petroleum coke,
pitch coke, carbon black, natural graphite and secondary graphite
scrap) are loaded and stored in raw materials silos. At the first
step, the raw materials are pulverized (ground) in crushers and
ball mills. The resulting powder is conditioned according to the
particle size distribution (screening). The final step of powder
preparation process is blending the powder with a binder. Coal tar
pitch, petroleum pitch or synthetic resins are used as binders.
