Featuring safety-oriented design, intelligent processes, and eco-friendly configurations, this equipment is suitable for recycling various types of waste lithium-ion batteries, including ternary lithium-ion batteries, lithium iron phosphate batteries, lithium cobalt oxide batteries, and lithium manganese oxide batteries. It provides a stable and efficient end-to-end solution for recycling projects with an annual capacity of 10,000 metric tons.


 

Equipment Composition

The lithium-ion battery recycling machine is an integrated, turnkey system. The main body of the equipment is constructed from Q234 steel. Wear-prone components are made of highly wear-resistant materials, ensuring high structural strength and a long service life. The entire system features a modular design, comprising core modules such as sealed feeding and conveying, multi-stage crushing, pyrolysis desorption, multi-stage fine sorting, exhaust gas purification, and PLC-based intelligent control. Equipment configurations can be customized to meet specific customer requirements, catering to all scenarios from small-scale laboratories to 10,000-metric-ton mass production.

This equipment offers exceptional adaptability and can efficiently recycle and process power batteries from new energy vehicles, batteries from 3C digital products, and batteries from energy storage systems. It can efficiently process a wide range of battery types, including cylindrical, prismatic, aluminum-cased, pouch, and blade batteries, demonstrating strong adaptability.

 

Process Flow

Xingmao Machinery’s lithium-ion battery recycling machine follows a core process path of “physical crushing, high-temperature pyrolysis, and multi-stage intelligent sorting.” The entire process operates under sealed, oxygen-free, and negative-pressure conditions. This ensures safety while enhancing sorting purity.
 

1. Sealed Feeding and Multi-Stage Crushing

Intelligent Feeding: A dedicated feeding platform is established, equipped with a vibrating feeder and a sealed conveyor. The stainless-steel sealed feed system features two buffer hoppers paired with pneumatic valves, enabling quantitative, controlled, and dust-free feeding. This prevents material blockages or idle operation.

Electrified Crushing: The core innovation is nitrogen-protected electrified crushing technology. The crushing chamber is fully enclosed and filled with nitrogen, thereby controlling oxygen content to within 2%. It is equipped with triple detection sensors for oxygen content, temperature, and flame detection. It can directly process small quantities of electrified batteries. Cutting tools and other components can be adjusted according to different battery types, allowing adaptation to various battery types and hardness levels.

Secondary Crushing and Grinding: The primary purpose of the hammer mill is to further break up and crush the material, preventing the positive and negative electrodes from sticking together. The material is crushed to a size of less than 3 cm. It is then processed through a grinder to reduce it to less than 2 mm, thoroughly removing the black powder from the positive and negative electrodes on the surfaces of the copper and aluminum foils. This lays the foundation for subsequent sorting.
 

2. High-Temperature Pyrolysis

Lithium battery high temperature cracking furnace is a critical process for removing electrolyte, plastic separators, and binders. Xingmao Machinery employs a combination of low-temperature drying and high-temperature pyrolysis. The system can be customized to meet customer requirements.

Low-Temperature Drying: Customers typically use traditional saltwater discharge, which leaves a large amount of moisture inside the battery. This process primarily removes moisture and electrolyte, thereby preserving the physical properties of the materials and facilitating subsequent pyrolysis.

High-Temperature Pyrolysis: In an oxygen-deprived environment, plastic separators, PVDF, and binders are thoroughly decomposed. The combustible gases produced by the pyrolysis of organic matter can be used for combustion-based heating. This process is commonly used in the deep processing of power batteries to enhance metal purity.


 

3. Multi-Stage Intelligent Sorting

After pyrolysis, the material undergoes a combination of processes—including magnetic separation, sorting, gravity separation, and vibrating screen separation—to achieve precise separation.

Magnetic Separation: Removes iron impurities. A strong magnetic field is used to separately screen out the battery’s magnetic casing.

Airflow + Gravity Separation: Utilizes density differences to efficiently separate copper particles, aluminum particles, and Black Mass.

Multi-Stage Sorting: Utilizes drum screens and ultrasonic vibrating screens to progressively extract Black Mass. This ultimately achieves a Black Mass recovery rate of ≥98% and a Black Mass purity of ≥98%, meeting industrial recycled raw material standards. The purity of Black Mass directly impacts the metal purity and cost of subsequent hydrometallurgical extraction.

 

4. Environmentally Friendly PLC-Based Intelligent Control

Environmental Closed-Loop System: All process stages operate in a sealed, negative-pressure environment. This is complemented by a pulse dust collection system, cyclone feeders, and exhaust gas purification systems. Workshop dust concentration is ≤20 mg/m³, meeting environmental protection standards and enabling efficient, green production.

Intelligent Control: Equipped with a Siemens S7-1200 PLC and a 10-inch industrial touchscreen, supporting remote monitoring and operation. Features real-time monitoring of temperature, pressure, and oxygen content, as well as automatic alarm functions for anomalies.

 

Advantages and Features

1. High Throughput: Utilizes a combination of multiple systems, including multi-stage crushing, drying and pyrolysis, and intelligent sorting. Processing capacity reaches 1–2 t/h. This represents a 50% increase compared to traditional lithium-ion battery recycling machines. Waste heat recovery reduces energy consumption by 20–30%. A 10,000-metric-ton-scale project can reduce carbon emissions by up to 12,000 metric tons.
2. High-Purity Recovery: The innovative process achieves industry-leading recovery rates and purity levels for black mass, copper, and aluminum. The higher purity of the black mass facilitates downstream hydrometallurgical extraction of lithium, cobalt, nickel, and other metals, significantly enhancing the project’s economic benefits.
3. Safety Protection: The system incorporates a nitrogen protection system, multi-level safety monitoring, and explosion-proof pressure relief design. This completely eliminates the risk of fire or explosion during the crushing process.
4. Universal Compatibility: A single set of equipment is compatible with multiple battery types, including cylindrical, blade-type, pouch, and prismatic batteries. It supports lithium-ion batteries from all major market systems, reducing capital expenditure for enterprises and enhancing the equipment’s compatibility and flexibility.
