For sizes above 100 microns, most hammer…

Ultrasonic Grinding of Natural Graphite - NASA/ADS

FINE grinding of graphite is usually carried out in a mortar or in a ball mill. The reduction of the particle size proceeds rather slowly due to the lubricating action of the grain surfaces, and the ground crystals contain various kinds of lattice imperfections including stacking faults-the extent of the imperfections being subject to the period and method of grinding.

Graphite typically has a hexagonal structure in a rhombic formation structure. This structure forms layer giving its key properties, such as the high electrical conductivity. Graphite follows a primary crushing and grinding comminution circuit, with froth floatation acting as a key final step. Graphite can have environmental issues.

Natural Flake Graphite | Asbury Carbons

Commercial flake graphite available for further grinding and processes is available in three primary sizes. These sizes are -100-mesh, +100-mesh, and +50-mesh. Depending on the source and requirements other more "exotic" cuts are available, but the above three are generally considered the work horses of the industry.

Machining graphite and carbon [SubsTech]

Graphite and carbon are generally machined dry without using Cutting fluids (coolants).If coolants are used in some machining operations (grinding, honing, polishing) the workpiece should be dried at 300-400°F (150-200°C) to remove liquids absorbed by the material.

US4533086A - Process for grinding graphite - Google Patents

For example, the graphite-oil agglomerates can be separated from the water and graphite grinding aid by filtering with bar sieves or screens which predominately retain the graphite-oil agglomerates, but pass water and unagglomerated graphite grinding aid. The result is a physical separation of the graphite grinding aid from graphite.
