Engineered for high-value recovery of critical battery raw materials, this turnkey solution processes spent Lithium-Iron-Phosphate (LFP) and Nickel-Cobalt-Manganese (NCM) battery packs. Utilizing continuous nitrogen-inerted primary shredding, low-temperature vacuum drying for electrolyte evaporation, and high-speed water-cooled fine grinding, the system cleanly isolates black mass (cathode/anode active material) from copper and aluminum foils without wet hydrometallurgical pollution.
