The Lead Smelting Rotary Furnace is mainly composed of the rotary furnace body,hydraulic transmission system, post-combustion device,sealing cover,ead discharge system,operating platform and control system.
Process description: lt effectively combines traditional precipitation smelting and reaction smelting, mainly smelting undesulfurized lead paste or desulfurized lead paste and lead grid, it designs with comprehensive position dust collection pipelines, adopts post-combustion mode and beam jet technology, which can increases the utilization rate of gas thermal energy by 20%, and effectively reducing the emission of exhaust gas and SO2.
Crude Lead Rotary Furnace Process Flow
The smelting process in a crude lead rotary furnace can be divided into six steps:
1. Pre-heating
First, the temperature of the rotary furnace is raised to above 1000°C to bring it to operating condition.
2. Charging Stage
Lead ore is charged into the rotary furnace together with coal and limestone. The coal acts as a reducing agent, and the limestone serves as a flux/neutralizing agent.
3. Slag Formation (Slagging-off)
High-temperature air supplied from a hot blast stove causes the oxygen in the gases generated by the reaction between the reducing agent and the lead ore to be reduced by elements like iron and silicon present in the gas phase. This produces a solid residue known as slag (or specifically, slag formed by air injection).
4. Formation of Sponge Lead (“Lead Wool”)
After a period of reaction, a portion of crude lead, known as sponge lead (often colloquially called “lead wool”), is generated within the rotary furnace.
5. Determining Optimal Smelting Duration
Based on the quality, temperature, and impurity content of the sponge lead, the appropriate smelting duration is determined.
6. Lead Tapping
After the optimal smelting time has elapsed, the molten sponge lead flows out from the furnace’s taphole (or via tilting the furnace), forming crude lead.
