System design supports stable feed ratio, residence time, and temperature control—critical for consistent sponge iron quality.
Optimized kiln shell, refractory lining options, and drive system for continuous high-temperature operation.
Sealed feeding and controlled cooling reduce operational risk; safety interlocks can be configured per project.
Dust collection and airflow control are designed according to local requirements and customer compliance targets.

Iron ore (lumps/pellets/fines briquettes where applicable) and reductant are prepared and batched according to process requirements.
A controlled feeding system maintains stable kiln load and helps reduce air leakage for safer operation.
Materials travel through the rotating kiln under a controlled temperature profile to achieve direct reduction and required metallization.
Hot sponge iron is discharged and cooled in a controlled way to improve safety and downstream handling.
Sizing/screening removes fines where needed, and the product is conveyed to storage or packing.
Process gas and dust are treated through dust collection (e.g., cyclone + bag filter) and related systems based on project standards.
