Rotary Kiln DRI & Sponge Iron Production Line Solution

This rotary kiln DRI production line is used to produce direct reduced iron and sponge iron from iron ore, iron concentrate, pellets or other iron-bearing materials. The raw material, reducing agent and additives are mixed and fed into the rotary kiln, where iron oxides are reduced into metallic iron under high-temperature reducing conditions without melting the material.

The complete line can include raw material preparation, rotary kiln reduction, cooling, magnetic separation, screening, dust collection and environmental control. It can be customized according to raw material analysis, fuel condition, target capacity, metallization requirement and plant layout, with support for process design, equipment supply, installation guidance, commissioning and operation support.

Frequently Asked Questions

Can the production line capacity be customized?
Yes. The production capacity can be customized according to raw material supply, kiln size, fuel condition, investment plan, plant layout and target product requirement.
The product quality is mainly affected by raw material grade, reducing agent quality, kiln temperature, residence time, reducing atmosphere, material ratio and cooling/separation process. These factors should be reviewed during process design and commissioning.
Yes. We can support new rotary kiln DRI production line projects as well as existing kiln upgrading, capacity improvement, energy saving, dust collection improvement and operation optimization.
