LNPE Graphite Spheronizing Machine - To Improve Yield From Spheroidization Processes Up to 60%

In recent years all Natural-flake graphite companies are looking for ways to add value to their run-of-mill graphite concentrates.

With the growth of electric vehicle (EV) industry, to upgrade the natural-flake graphite for lithium-ion batteries application will be a good choice. For lithium-ion battery anodes, current industry practice is to mill and spheronize graphite concentrate prior to purification with hydrofluoric acid (HF). Typical yield of anode graphite from this process is 35%.

LNPE Powder Equipment Company has LNPE has invented a new type of graphite spheroidizing machine that can increase the yield to 60%.

The graphite grinding and shaping production line developed by LNPE is mainly composed of 1 impact mill, 8 shapers, 1 finished product mixing system and supporting pneumatic conveying system. The production line runs fully sealed, under negative pressure, which significantly reduces the generation of process dust.
