Our independently developed crushing and sorting production line for waste lithium batteries adopts a technology scheme that differs from mainstream market solutions in key process stages, achieving safer, more efficient, and environmentally friendly recycling and treatment.
We use high-speed shear crushing technology under nitrogen protection, replacing the commonly used low-speed double-shaft shredders. This technology can instantly break the battery’s power structure, fundamentally preventing the risk of thermal runaway caused by internal short circuits. The crushing environment is maintained in a nitrogen atmosphere, with oxygen concentration precisely controlled below 5%. This not only suppresses the generation of harmful hydrogen fluoride gas and directs the conversion of fluorine into solid lithium fluoride, but also improves subsequent separation efficiency by thoroughly flipping and loosening the material, preventing electrode sheets from wrapping the powder.
We innovatively apply electromagnetic pyrolysis technology. By utilizing the high content of metals such as copper, aluminum, and iron in the crushed battery material, electromagnetic induction simultaneously heats both the furnace and the material itself, increasing thermal efficiency from approximately 50% in conventional gas rotary kilns or resistance belt furnaces to over 90%, directly reducing nearly half of the thermal energy cost. This technology features a static furnace body with an internal material-propelling design and excellent sealing performance, fully addressing the safety risks of flammable and explosive electrolytes and organic gases. Moreover, the preheating and baking time is shortened from 3 hours to 1 hour, significantly improving the production line’s operational efficiency.
