Small Lithium Battery Recycling Machine

With the explosive growth of new energy vehicles and the energy storage industry, demand for lithium batteries continues to climb. However, the accompanying issue of waste lithium battery disposal is becoming increasingly severe. According to incomplete statistics, by 2025, the global volume of waste lithium batteries will exceed one million tonnes. Improper handling of these batteries not only wastes resources but also causes environmental pollution. Consequently, the lithium battery recycling sector is accelerating technological innovation, achieving resource circularity through efficient, environmentally sound processes and equipment. With our advanced integrated solutions and lithium battery recycling machine, we have become an industry benchmark.

Small-scale lithium battery recycling machine capacity

Lithium battery recycling machinery is categorised into large, medium, and small processing capacities. Small-scale lithium battery recycling machines typically operate at capacities ranging from 100kg/h to 500kg/h. We offer customised lithium battery recycling solutions tailored to clients’ production requirements. The core objective of lithium battery recycling is to extract valuable metals (such as nickel, cobalt, and lithium) for reprocessing into recycled materials, ensuring safety and harmlessness throughout the recovery process.

Small-Scale Lithium Battery Recycling Process

Mainstream processes comprise three critical stages: pre-treatment, crushing and sorting, and material reprocessing.

Pre-treatment: Safe Disassembly and Stabilisation

Waste lithium batteries must first undergo disassembly, including removal of casings. Particularly for new energy vehicle battery packs, disassembly into modules is required. Modules are then further dismantled into individual lithium battery cells. Pre-treatment steps like discharging and casing removal are essential to eliminate operational risks associated with handling charged batteries. Our ‘Oxygen-Free Crushing System’ demonstrates unique advantages in this context:

• Dedicated Feeding Platform: Automated feeding system compatible with various battery specifications, enhancing production efficiency.
• Specialised feed design: Ensures smooth material entry, preventing blockages.
• Medium crushing technology: Shreds waste lithium batteries into block-like fragments. Facilitates heat dissipation and prevents encapsulation caused by softened plastic separators.
• Automatic reversal mechanism: Assists in processing stubborn materials by reversing rotation, ensuring stable equipment operation.
• Cooling and safety protection: Primary crushers and conveyors feature water-jacketed cooling systems. Detects oxygen/nitrogen levels and flame presence. Prevents temperature runaway. Equipped with explosion venting devices.

Crushing and Sorting: Precise separation of core valuable materials

Within the entire system, secondary crushing and sorting form the critical stage. Achieves efficient resource recovery through multi-stage physical separation technology:
Specialised Lithium Battery Crusher:

• Live, oxygen-free shredding: Utilises a dedicated lithium-ion battery shredder compatible with all types of waste lithium batteries. Capable of direct live processing. Reduces pre-treatment costs.
• Thorough Material Dispersion: Shredded material undergoes further fragmentation via hammer crushers for optimal screening compatibility.
• Intelligent Control: Continuous oxygen/nitrogen concentration monitoring with PLC-based intelligent control system ensures operational safety.
• Maintenance Accessibility: Entire equipment features access panels for streamlined maintenance and servicing.
• Multi-stage sorting process: Pre-treated material undergoes crushing, screening, magnetic separation, and grinding. Subsequent separation via drum screens, magnetic separation, and gravity sorting yields components including black mass, copper, aluminium, plastic separators, and iron casings. Multiple screening stages combined with pyrolysis and de-powdering achieve material purity exceeding 98%.

Material Regeneration: Closed-Loop Recycling and Environmental Safety

Black Mass separated by the compact lithium battery recycler undergoes pyrometallurgical roasting and hydrometallurgical extraction. Recovered metals are reused in lithium battery production. Plastic separators and magnetic casings undergo pyrolysis to alter their chemical properties. The entire recycling system incorporates gas purification units to treat fluorine-containing gases and dust generated during crushing and pyrolysis. This ensures exhaust emissions meet regulatory standards, achieving full process harmlessness.
