Complete Lead Acid Battery Recycling Solutions: From Breaking to High-Purity Lead Ingots

With millions of used lead acid batteries (ULAB) reaching end-of-life every year, the demand for efficient and environmentally responsible lead acid battery recycling equipment has never been greater. Regulatory pressure is tightening across the globe, and businesses that invest in modern recycling infrastructure are not only protecting the environment but also unlocking significant revenue streams from recovered lead, plastic, and acid.

At San Lan Technologies Co., Ltd, we have spent over 15 years helping recycling entrepreneurs and industrial operators build profitable, compliant battery recycling plants from the ground up. Our turnkey solutions cover every stage of the process, from initial breaking and separation to high-purity lead refining.

The Complete Recycling Line: What You Need

A profitable lead acid battery recycling plant requires more than just a single machine. It demands an integrated system where each unit complements the next. Our lead acid battery breaking and separation system forms the foundation of the operation, efficiently crushing incoming batteries and classifying the output into four distinct fractions: lead paste, lead grid, plastic (PVC/PP), and hard rubber.

With a throughput capacity of 1 to 10 metric tons per hour, our breaking and separating plant is designed for both small-scale recyclers and large industrial facilities. The system handles the complete spectrum of battery types while maintaining high separation efficiency and minimal material loss.

From Paste to Pure Lead: Smelting and Refining

Once the lead paste is separated, it must be reduced to metallic lead. We offer multiple furnace technologies to match your capacity and budget requirements:

• Rotary Furnace for Paste Reduction: Capacity ranges from 2 to 20 metric tons per batch, delivering higher lead recovery rates than conventional blast furnace designs.
• Blast (Cupola) Furnace: Designed for continuous operation with a capacity of 40 to 100 metric tons per 24-hour period and a lead recovery rate of 95%. Maximum operating temperature reaches 1800°C.
• De-sulfurization Unit: Pre-treats lead paste to remove sulfur from PbSO4, which lowers melting temperatures, reduces SO2 emissions, and cuts energy and additive consumption.

For operators seeking the highest product purity, our lead refinery furnace refines crude lead to 99.999% purity. We offer both natural gas/diesel heated and electric heated models. The electric variant uses near-infrared heating technology and can reduce energy consumption by 30% to 50% compared to traditional systems.

Environmental Compliance Built In

Modern battery recycling cannot succeed without rigorous pollution control. Our integrated air pollution control systems are engineered specifically for rotary furnaces, blast furnaces, and refinery kettles, ensuring that all exhaust gases are purified before release and that your facility meets local and international environmental standards.

We also supply water treatment plants designed to handle acidic wastewater generated during the breaking and separation process, as well as filter press systems for efficient lead paste collection. Every component is selected to help you operate responsibly and avoid costly regulatory penalties.

Beyond Equipment: True Turnkey Support

San Lan distinguishes itself from ordinary recycling equipment supplier companies by offering comprehensive EPC (Engineering, Procurement, Construction) project services. Our technical team includes mechanical engineering graduates with more than 15 years of hands-on experience in e-waste recycling machinery.

Our value-added services include:

• Customized plant design and layout optimization
• One-stop equipment procurement
• On-site installation and commissioning
• Operational training for your workforce
• Assistance sourcing waste battery feedstock (cable scrap, PCB scrap, used lead acid batteries)
• Support selling recovered products (copper rice, copper powder, lead ingots)
• Investor and partnership matching for plant construction projects

A Global Track Record You Can Trust

Since our founding in 2007, San Lan Technologies has supplied recycling equipment to customers in more than 21 countries, including Singapore, Colombia, Vietnam, Mexico, Argentina, Korea, Malaysia, Indonesia, South Africa, Tunisia, India, Kenya, Saudi Arabia, Philippines, and Zambia. Our clients range from independent recyclers to government-backed waste management programs.

In addition to lead acid battery recycling, we manufacture complete lines for lithium-ion battery recycling, cable recycling, circuit board recycling, refrigerator and AC recycling, CRT processing, and motor dismantling. We also produce mining equipment including lithium ore extraction plants and nano ceramic grinding media for ball mills.
