Lead Smelting Rotary Furnace is core thermal equipment for recycled lead smelting, mainly processing lead plates, lead paste and crude lead separated from waste lead-acid batteries. The rotary cylinder rotates at constant speed to ensure uniform heating of materials. Equipped with supporting combustion, dust collection and desulfurization systems, it smelts lead-containing materials into crude lead under high-temperature reduction environment. Operated under sealed negative pressure to collect and harmlessly treat smelting flue gas. Suitable for large-scale waste lead recycling lines with stable energy consumption and high metal direct recovery rate.
