cascading series of jet mills. They are crushed by impact, collision, friction and shearing using a high speed rotating plate and classified to separate the target size range which then goes into the next mill. Once the final target size has been achieved, the micronized graphite is then "rounded" which essentially involves rolling the

Abstract. Graphite and carbon powders occur in many different forms and emanate from many different sources. A systematic classification is given based on the degree of crystallinity, from lowstructured coke and coal products to macrocrystalline graphite and nanocarbons. In the family of 'carbon black' the highly conductive products ...
