Air Classification, Compaction and Milling of Lithium Compounds for Battery Applications. Chemicals are air classified according to size or density. Air classification provides the most effective means for separating a product from a feed stream, for dedusting, or when used in conjunction with grinding equipment for increasing productivity.

Air classifier devices have a distinct advantage over other systems used to separate materials. They maximize the mill's capacity and therefore constitute efficient methods of reducing the energy consumption of crushing and grinding operations. Since improvement in their performance is challenging, the development of an efficient modeling system is of great …
