The drying of lithium carbonate produces excess fines. A Sturtevant SuperFine Air Classifier can successfully remove 30-40% of the lithium carbonate powder as battery grade product prior to milling. Therefore, only 60-70% of the lithium carbonate feed needs to be compacted and milled due to pre-classifying. As a result, a smaller sized compactor and mill are needed due to the reduced capacity requirements.
Sturtevant & Komarek developed a better way to process lithium that saves capital and operational expenses by eliminating ancillary equipment and reduces energy consumption by 50%.
The new process saves CAPEX and OPEX and involves classifying, compacting and milling the lithium carbonate in the following 3 steps.
