Solid sulfur is processed through a dedicated melting section to provide a consistent feed for the downstream combustion stage. Recovered process steam is reused for sulfur melting to improve heat utilization.

Sulfur is combusted to generate sulfur dioxide for downstream conversion, while the waste heat boiler recovers process heat. Recovered steam is reused for sulfur melting and equipment heat preservation within our battery manufacturing facilities.

The plant adopts a 3+2 double-conversion double-absorption (DCDA) process, achieving an SO₂ conversion rate of at least 99.85% to support efficient and stable sulfuric acid production.

The absorption system achieves an absorption efficiency of 99.99%, supporting the production of sulfuric acid at a concentration of 98.5% H₂SO₄ for battery manufacturing and external industrial supply.

The tail gas stack serves as the final outlet for the process gas stream after the main conversion and absorption stages, completing the sulfuric acid production process.

Large lead kettles equipped with mechanical stirring and fume collection systems support controlled molten lead processing before casting or further refining.

Molten lead is cast into standardized lead products for efficient handling, storage, and transfer to downstream refining and manufacturing processes.

Dedicated fume collection and dust removal systems capture and control process fumes and particulate matter generated during high-temperature lead smelting, supporting cleaner and more controlled production operations.

Cast lead products are organized for storage and transfer to downstream lead refining and manufacturing operations.

Equipped with 18 grid casting machines, our workshop produces a wide range of cast grids for motorcycle, sealed lead-acid, electric vehicle, tubular, and other battery applications, supporting flexible production across multiple battery types.

Our fully automated red lead production system provides an in-house supply of red lead material, with a daily production capacity of up to 7 tons to support specialized battery plate manufacturing requirements.

The lead oxide section operates 12 fully automated lead powder machines, with each machine capable of producing up to 28 tons per shift, providing stable material supply for continuous battery plate production.

Five automotive battery plate pasting lines and four specialty battery plate lines are supported by fully automated paste mixing systems, enabling efficient and consistent plate production for different battery applications.

Three fully automated punched-grid lines produce grids for automotive and motorcycle battery plates, while four automated expanded-grid lines support a wide range of standard automotive battery plate specifications.

The tubular plate section is equipped with 8 die-casting machines, 5 powder-filling machines, and 12 bottom-sealing machines, supporting a daily production capacity of up to 18,000 tubular positive plates.

Our plate formation section operates 32 external formation lines, supported by dedicated plate drying rooms, washing systems, and plate separation equipment to complete the final stages of battery plate processing.

The rotary anode casting system integrates casting, cooling, and demolding into an automated production process, with a capacity of up to 260 lead anode plates per hour, providing consistently formed anode plates for electrolytic refining.

A large-scale electrolytic cell system forms the core of the facility, using crude lead anode plates for wet electrolytic refining. With a designed annual capacity of 60,000 tons, the process produces high-purity electrolytic lead while supporting the recovery of valuable metals.

After electrolysis, residual anode plates are automatically washed to remove anode slime and remaining electrolyte before being returned to the lead melting process for reuse. Recovered process materials are collected for further valuable-metal recovery, improving overall material utilization.

The automated cathode sheet production system forms uniform starter sheets for the electrolytic refining process, with a production capacity of up to 370 cathode sheets per hour, supporting continuous and stable electrolysis operations.

The electrolytic lead ingot casting line integrates molten lead casting, cooling, and ingot release in an automated process. With a production capacity of up to 25 tons per hour, the system supports continuous production of consistently formed finished electrolytic lead ingots.
