Complete Equipment for Waste Lead-Acid Battery Recycling and Secondary Lead Smelting
Lead-acid Battery Recycling Secondary Lead Smelting Environmental Protection Equipment Lead-acid Battery Recycling Production Line Lead Paste Smelting
The company provides complete equipment covering pretreatment sorting and secondary lead smelting refining for waste lead-acid batteries, enabling integrated closed-loop production from battery crushing to crude lead smelting and refining purification. The front-end sorting system uses fully enclosed negative pressure mechanical shredding, gravity separation, air screening, and acid mist purification to automatically dismantle automotive, energy storage, and industrial waste lead-acid batteries, efficiently separating lead paste, lead grids, PP plastic, and spent electrolyte. The back-end smelting system includes a closed rotary furnace, refining furnace, desulfurization, flue gas purification, and ingot casting, producing high-purity secondary lead ingots meeting national ultra-low emission standards.
This exhibit consists of complete equipment for waste lead-acid battery recycling and secondary lead smelting, serving as an integrated solution for lead resource circular utilization.

Front-end Waste Battery Recycling & Sorting Unit

The front-end waste lead-acid battery recycling and sorting equipment adopts fully enclosed negative-pressure mechanical shredding, gravity separation, air classification and acid mist purification based on full physical processes. It automatically dismantles automotive starter batteries, energy storage lead-acid batteries and industrial spent lead batteries to efficiently separate four products: lead paste, lead grids, PP plastics and waste electrolyte.
 
Operating under full enclosed negative pressure and equipped with comprehensive treatment systems for waste gas, waste liquid and solid residues, the line prevents dust leakage and excessive acid mist emission with qualified environmental compliance, high automation and superior sorting purity.

Back-end Complete Secondary Lead Smelting Equipment

The matched back-end smelting lineup includes sealed rotary furnaces, refining furnaces, impurity & desulfurization units, flue gas purification systems and ingot casting facilities. Pre-sorted lead paste and lead feedstock undergo low-temperature high-efficiency smelting, desulfurization and refining to eliminate impurities such as sulfur, iron and copper for high-purity secondary lead ingots.
 
Featuring low energy consumption, complete flue gas capture and minimal solid waste output, the full smelting line meets China’s ultra-low emission standards for the secondary lead sector. It enables large-scale harmless treatment, resource regeneration and high-value utilization of waste lead resources, catering to standardized continuous production of large-scale secondary lead manufacturers.
