Top Five Grinding and milling technics for Graphite ...
Graphite Graphite is a dark gray to black mineral with a metallic luster, it has relatively low hardness(0.5-1 in Mohs). However, because of graphite's often occurrence as flakes and the covalent bonds strength within the sheet-like graphene, it is very hard to grind graphite to fine particle size. For sizes above 100 microns, most hammer…

Fourth, graphite machining should be done with very sharp tooling to prevent particle pull-out or edge chipping. Once a cutting tool has lost its sharp edge it will fracture the graphite material or cause a blowout of an edge when exiting a cut. This is because the dull tool is pushing and not cutting the material.
