Rotary Kiln
Designed for continuous thermal processing, the rotary kiln uses an inclined, rotating shell to move material through the heating zone. Application-specific systems are available for lime production, bauxite calcination, cement clinker production and lightweight aggregate manufacturing. Kiln dimensions, lining, heating equipment and supporting systems are selected according to the material and process requirements.
- Applications: Lime, bauxite, cement clinker and lightweight aggregates
- Kiln Diameter: 1.4–5.6 m across the listed models
- Kiln Length: 33–87 m across the listed models
- System Configuration: Selected according to material, capacity and thermal process
Key Features
Continuous Thermal Processing
The inclined, rotating shell moves material through the kiln while exposing it to heat for the required calcination or thermal treatment process.
Adjustable Rotational Speed
Kiln speed can be adjusted within the selected model’s operating range to help control material movement and residence time.
Application-Specific Lining & Seals
Refractory lining and kiln-end sealing arrangements are selected to suit the material, operating temperature and process conditions.
Integrated Process Equipment
The kiln can be combined with suitable feeding, preheating, cooling, gas treatment and control equipment to form a coordinated production system.
Design & Working Principle
Example of a rotary kiln system for lightweight aggregate production. Process stages and equipment configuration vary according to the raw material and final product requirements.
- Prepared material enters the higher end of the kiln. The shell’s inclination and rotation move it gradually toward the discharge end.
- As the material passes through the kiln, heat drives the required calcination or thermal reactions. Operating conditions are selected for the specific material and target product.
- The treated material is discharged for cooling and downstream handling. Exhaust gases pass through the gas treatment equipment specified for the process.
