How a Rotary Kiln Dam Works. A dam in a rotary kiln works much like a dam in a river; material builds up behind the dam, forcing retention time and bed depth to increase. Material then spills over the dam, and discharges from the rotary kiln. Since most kilns utilize a counter current air flow, end dams are the most commonly employed type of dam.

As a high-temperature device, the analysis of a material's thermal properties is the foundation of rotary kiln design. Factors such as a material's specific heat, thermal conductivity, heat transfer properties, and more, will all influence how that material will behave in the kiln, and ultimately, how the kiln will need to be designed to ...

In the FEECO design process, once we have engineered a rough design of the rotary kiln, we use several computer programs to help predict and model how the material will behave in the rotary kiln we have designed. We review the combined analyses, and if our design does not meet the appropriate criteria, we adjust accordingly. Conclusion
