Start with Dry Material. Second, the starting raw graphite material should be dry before machining. If your raw material stock has been stored outside or been exposed to water it should be baked to drive out any excessive moisture. The water and dust will make an abrasive slurry, which will dramatically reduce your tool life.Web

Micronizing of flake graphite concentrate is achieved by multi-stage steps as the flakes move through a cascading series of jet mills. They are crushed by impact, collision and friction using a high-speed rotating plate and classified to separate the target size range which then goes into the next mill until the flake size is reduced to 5–20 μm.Web
