Lithium Battery High Purity Black Mass Recycling Line
Our newly upgraded lithium-ion battery recycling system is now fully operational, delivering significant advancements in energy efficiency, safety performance, and black powder purity. Whether you focus on recycling ternary batteries, lithium iron phosphate batteries, or hybrid types, this system provides more stable and efficient processing, enabling more precise and controllable separation of black powder, copper, aluminum, and other materials.
Core Process Upgrade: Comprehensive Breakthroughs from Pyrolysis to Black Powder Purification
The standout feature of the new system is its electrically heated pyrolysis furnace. Unlike traditional gas-fired heating, it heats only the furnace body while maintaining ambient temperatures elsewhere. This design not only reduces energy consumption by approximately 50% but also enables a more precise temperature control curve during heating. This temperature precision stabilizes decomposition reactions during battery pack pyrolysis, providing cleaner feedstock for subsequent separation stages.
To further boost black powder recovery rates, we redesigned the water-cooling system for higher heat exchange efficiency during cooling cycles. More stable temperature control preserves material integrity, naturally increasing black powder yield and purity.
In the crushing and grinding stage, the newly introduced ultra-fine pulverization system stands out as a key upgrade. Operating at high speeds of 3000 rpm, it can separate 80% of black powder from positive and negative electrode materials in a single pass. Compared to traditional hammer crushers, this method not only achieves higher efficiency but also minimizes material damage. The pulverized material immediately enters the sorting system. Under the influence of dynamic airflow, black powder is precisely captured while copper and aluminum particles are effectively separated. By adjusting air velocity and flow field structure, the aluminum content in the black powder can be stably controlled below 0.5%. For customers with higher requirements, aluminum impurities can be reduced to as low as 300ppm.
Automated Separation System: Purer Copper and Aluminum, Cleaner Black Powder, More Energy-Efficient Recycling
The redesigned inclined screen structure achieves more thorough stratification of copper-aluminum mixtures. Under combined tilt and vibration, materials naturally separate, forming distinct boundaries between high-density and low-density components to ultimately deliver higher copper and aluminum purity. Any non-compliant mixed material is automatically recycled to the front end for reprocessing, eliminating waste and manual intervention.
The highly automated gravity separation system further enhances the completeness of final copper-aluminum separation. Stable flow rates, adjustable air volume, and multi-angle grading structures ensure materials of varying particle sizes and densities follow optimal separation trajectories. The entire process requires minimal human judgment, with the system using data to ensure stability and consistency for each batch of material.
At the end of the production line, a fully automated black powder packaging system ensures continuity from separation to bagging. Operators only need to replace the packaging bags every 1 to 1.5 hours to maintain stable production line operation, significantly reducing labor costs.
This lithium battery recycling system represents not merely an equipment upgrade, but a complete restructuring of the technological chain. Lower energy consumption, higher purity, and smarter separation logic transform black powder into a truly high-value-added recycled material. Should you require further details on system configurations, black powder purity data, or production line solutions, we stand ready to provide comprehensive technical documentation and customized support.
