Metallurgical Rotary Kiln

Metallurgical Rotary Kiln is a high-temperature industrial system purpose-built for the reduction, oxidation, and calcination of rare earth ore, iron powder, sponge iron, and other metallurgical materials. 

Designed for the mining and steel industries of Brazil, Peru, Chile, and across South America, this kiln delivers precise thermal control, uniform reactions, and durable performance in harsh mining environments. It is ideal for both new metallurgical processing plants and production line upgrades.

Key Technical Highlights

Precision Multi-Zone Temperature Control: 

Independent heating zones (up to 1300°C) with ±2°C accuracy ensure uniform reduction/oxidation reactions, maximizing the purity and yield of rare earth concentrates and sponge iron.

High-Temperature Resistant Construction: 

Heavy-duty refractory lining and alloy steel components withstand continuous high-temperature operation, with minimal wear from abrasive metallurgical materials.

Continuous & Uniform Material Processing: 

Optimized rotary speed and internal lifters ensure even material movement, eliminating hot spots and guaranteeing consistent product quality.

Multi-Fuel Compatibility: 

Supports coal, natural gas, diesel, and biomass heating to adapt to local energy resources across South America, reducing operational costs.

Sealed & Leak-Proof Design: 

Double-layer seals prevent gas leakage during reduction processes, improving safety and maintaining the controlled atmosphere required for metallurgical reactions.

Low-Maintenance Heavy-Duty Drive System: 

Reinforced riding rings, support rollers, and gearboxes are built to handle heavy loads and continuous operation in remote mining sites, minimizing downtime.

Modular & Customizable Layout: 

Kiln dimensions and configurations tailored to your specific process requirements, from small-scale rare earth projects to large sponge iron production lines.
