The rotary kiln is used in many solid processes, including drying, incineration, heating, cooling, humidification, calcination and reduction. This widespread application can be attributed to factors such as the ability to handle varied loads, with large variations in particle size [1].The rotary kiln is a slightly inclined steel cylinder that rests …
Owing to its design and intense thermal processing capabilities, the rotary kiln has been an industrial workhorse for the thermal destruction of hazardous waste. When properly operated, kilns can achieve over 99.99% destruction efficiency of some very toxic materials including chlorinated compounds.

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

For these most common rotary kiln materials, high temperatures in the range of 1100°C / 2000°F are used to instigate a chemical conversion (cement and lime) or to fuse fines (fine ore powder) into pellet form (iron ore). Most rotary kilns are direct fired – with a flame shooting into the kiln from the discharge end

While rotary dryers are often available in standardized models, designing a rotary dryer around the unique characteristics of the material and process needs will produce the best results and offer the most reliability. Various aspects of the dryer are considered during initial design in order to reach the exact desired parameters of the end ...
Because this new type of kiln had much greater capacity and burned more thoroughly and uniformly, it rapidly displaced the older type kilns. It has been further mentioned that the factor that contributed to the tremendous surge of Portland cement between 1880 and 1890, reportedly from about 42,000 to 335,000 barrels, was the development of the rotary kiln …
For evaporating moisture from concentrates or other products from plant operations, Rotary Dryers are designed and constructed for high efficiency and economy in fuel consumption.
