The October 2018 article described preparing natural flake graphite for lithium-ion battery anodes through grinding and spheroidization.
The published configuration comprised one impact mill, eight shapers, a finished-product mixing system and pneumatic conveying. The line was enclosed and operated under negative pressure to help contain process dust.
The article reported a yield improvement for this process. Yield depends on feed grade, target size distribution, morphology and accepted-product definition; the historical percentage is not a guarantee for all graphite feedstocks or lines.
