Rotary furnace for recycling used lead-acid batteries: a key technology for environmental protection, recycling, and resource circulation

#Industry ·2026-04-24

In the modern industrial system, lead-acid batteries are widely used in automobiles, power storage, and other fields due to their stability and high cost-performance. However, the disposal of a large number of waste batteries has also brought serious environmental challenges. Rotary furnace technology, as the core process for the resource recovery of waste lead-acid batteries, is driving the development of the circular economy with its high efficiency and environmental friendliness. The rotary furnace achieves the separation and recovery of metallic lead, plastic, and electrolyte from lead-acid batteries through a high-temperature smelting process. Its unique rotating design ensures uniform heating of materials, with a lead recovery rate of over 98%, far exceeding that of traditional processing methods. At the same time, the accompanying waste gas purification system effectively treats harmful substances such as sulfur dioxide generated during the smelting process, ensuring that emissions meet international environmental standards. This technology not only solves the hidden danger of lead pollution, but also converts waste batteries into high-value recycled lead resources, greatly reducing reliance on primary lead ore. With the increasingly stringent global environmental policies and the growing demand for resource recycling, rotary furnace technology has become an important pillar for the upgrading and transformation of the battery recycling industry, providing key technical support for the construction of a green manufacturing system.
