Rotary furnace for recycling used lead-acid batteries: an efficient recycling method and a new choice for environmental protection

#Industry ·2026-04-16

With the development of industry and the popularity of electric vehicles, the number of used lead-acid batteries has increased dramatically. How to safely and efficiently handle these batteries has become an important issue in the field of environmental protection. Rotary furnace technology, as a mature recycling method, is gradually becoming an ideal choice for processing used lead-acid batteries. The rotary furnace effectively separates components such as lead, plastic, and sulfuric acid from used lead-acid batteries through a high-temperature smelting process. Its unique design allows the furnace body to rotate slowly, promoting uniform heating and thorough reaction of materials, which significantly increases the metal recovery rate while reducing the generation of harmful gases and residues. Compared with traditional processing methods, the rotary furnace has the advantages of low energy consumption, minimal pollution, and high purity of recycled materials, meeting the requirements of modern circular economy and green development. In addition, the rotary furnace technology can maximize the utilization of waste resources. The separated lead can be reused in battery manufacturing, and by-products such as sodium sulfate can also be used in industry. This not only reduces the pressure on the extraction of natural resources, but also brings win-win economic and social benefits to enterprises. Choosing the rotary furnace to process used lead-acid batteries is a positive contribution to environmental protection and an important step in promoting sustainable development.
