Both proved that replacing the fine crushing and coarse grinding equipment in traditional technology with a high pressure roller mill can better protect the crystal structure of flake graphite in the rough grinding stage, improve crushing efficiency, shorten process flow, and reduce process flow energy consumption.
Crystalline flaky graphite was ground in a dry attrition system equipped with a vacuum apparatus. It was found that a low pressure and high temperature environment in the grinding of graphite promotes the size reduction down to submicron sizes while maintaining flaky shape.
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.
