Our rotary lead smelting furnace is a highly efficient thermal processing unit specially designed for secondary lead recovery. It handles spent lead acid batteries, lead paste, lead slag and various lead-bearing waste materials. Under continuous rotating operation, it completes roasting, reduction and smelting to separate crude lead from slag. Manufactured according to ISO9001 standards and supported by independent metallurgical patents, this rotary furnace delivers stable output, high metal recovery and reliable environmental performance for modern lead recycling projects worldwide.

Unlike static smelting furnaces, our rotary furnace cylinder operates at controllable low rotating speeds during operation. This innovative design ensures raw materials continuously roll and turn inside the chamber, allowing every material particle to fully contact high-temperature flue gas and heat sources.

• Eliminates dead zones of insufficient heating
• Enhances even mixing of feedstock, flux and fuel
• Improves chemical reaction efficiency
• Prevents local over-burning or incomplete smelting
• Significantly increases lead recovery rate
• Reduces unreacted residues in slag

The heavy-duty cylinder shell utilizes thick pressure-resistant steel plate with multi-layer wear-resistant refractory lining built inside to resist erosion from high-temperature molten mass and flue gas, extending service life and reducing lining replacement frequency.

The furnace features an optimized combustion and heat distribution system with adjustable combustion power based on actual feedstock conditions and production targets. Heat is fully utilized within the rotating cylinder rather than wasted through flue gas.

• Lowers unit fuel consumption per ton of lead product
• Reduces heat loss through furnace shell
• Real-time monitoring of key temperature points
• Prompt adjustment of combustion parameters
• Maintains stable thermal field conditions
• Prevents refractory lining damage from temperature fluctuations

Advanced sealing assemblies installed at both feeding and discharging ends of the rotary cylinder minimize flue gas leakage during operation, ensuring toxic and dust-containing gases are properly contained and directed to downstream treatment systems.

• Prevents gas escape into workshop environment
• Guides all exhaust to dust removal and desulfurization equipment
• Ensures compliance with environmental emission requirements
• Prevents cold outside air from entering furnace chamber
• Maintains stable internal temperature
• Eliminates extra energy loss from cold air inflow

This rotary lead smelting furnace supports flexible production rhythms and adapts to variable raw material compositions and different daily output requirements. It functions effectively as standalone equipment or integrates seamlessly into fully automated spent lead battery recycling lines.

• Connects smoothly with upstream and downstream equipment
• Accessible structural layout for main wearing components
• Enables inspection and maintenance without large-scale disassembly
• Convenient checking and replacement of key components
• Modular layout reduces equipment downtime
• Customizable dimensions, capacity, and configurations
