Ultrafine graphite powder is one type of graphite powder. The raw material of ultrafine graphite powder is natural flake graphite, which is crushed using an airflow grinder or ultrafine micro grinder. Ultrafine graphite powder with a particle size of 6-10 μ m. It's ultrafine graphite powder.

The preparation process of ultrafine graphite powder is as follows: natural flake graphite and raw material coke enter the crushing chamber through a feeding injector with compressed air, and are distributed at the nozzles outside the crushing chamber to inject ultra-high speed airflow into the crushing chamber, causing the coke powder to collide and rub with each other at high speed to form micro powder. The airflow with micro powder is discharged into the grading chamber through the outlet pipe, separating the coarser particles and being crushed again through the return pipe, The remaining micro powder is collected in stages using a cyclone separator and a bag collector. Ultrafine graphite powder is produced. Ultrafine graphite powder, due to its stable properties, can be widely used in conductive materials, wear-resistant and lubricating material batteries, atomic energy industry and national defense industry, color picture tubes, and other fields. Ultrafine graphite powder can be used in civil use to form metal cornerstone graphite composite conductive materials by combining with metals. Ultrafine graphite powder is used as a lubricant in the mechanical industry, and in the field of color picture tubes. The graphite emulsion made of ultra-fine graphite is used as a neutron reducer and protective material in atomic reactors in the atomic energy industry and national defense industry.
