After one rotation of the converter, the lead is given a new life — the rotary furnace for smelting waste lead-acid batteries

#Industry ·2026-03-19

When the last fuel-powered vehicle is decommissioned and every scrap lead-acid battery is solemnly recycled, it's not the end, but the starting point of the next green cycle. What we bring is not the billowing smoke from traditional smelting, but cutting-edge technology that allows lead to be "reborn from the fire" in a closed-loop rotary furnace. It's like an elegant dancer, slowly rotating at a rhythm of 0.5–3 r/min, allowing the high temperature of 1,000°C in the furnace to evenly embrace every particle of lead paste; it's more like a rigorous chemist, with oxygen-enriched bottom blowing, automatic temperature control, and dual recovery of sulfur and nitrogen, reducing SO₂ by 98% and boosting lead recovery to 99.3%, redefining the term "hazardous waste". Modular design allows on-site assembly in 2 hours; DCS one-click start/stop and remote monitoring via mobile phone; and corrosion-resistant linings with a 3-year lifespan, reducing lead energy consumption by 18%. What we save is not just cost, but also the Earth's breath. From battery crushing to low-temperature melting, from lead alloy refining to plastic separation, the entire closed-loop production line has been operating stably in 17 certified disposal centers in China, with the longest record of 482 days without major repairs and cumulative CO₂ emission reductions equivalent to the carbon absorption of 3.2 million trees over 20 years. Choosing a rotary furnace is choosing a proven "double-carbon" shortcut: • Pass environmental impact assessment once, eliminating the "neighborhood resistance" effect • Industry-leading direct metal recovery rates and visible profit increases • Full-component recovery of black powder, acid solution, and plastic, truly "making the most of every resource" Today, let every scrap battery become a resource coordinate, and let every rotation contribute to reducing the Earth's burden. Lead-acid battery recycling rotary furnace One rotation of the furnace, and lead is reborn; the fire never dies out, and green never stops.
