Rotary kilns are integral to modern industrial processing, providing a controlled means of initiating chemical reactions and phase changes. As they are highly flexible and can be used to process hundreds of different materials, optimizing the performance of a rotary kiln around the process and material at hand is an important aspect of kiln design.
· In the standard design, the rotary kiln tyres were mounted loosely on the kiln shell. Inevitably, the rotary tyres are cooler than the kiln shell, and so a small gap allows differential expansion to take place. The gap is usually designed to be about 0.2% of …
· Rotary kiln sizing and design. Every material is different in terms of how it behaves in the kiln and at what temperatures different reactions are going to occur. When designing a process around a rotary kiln, as well as in the design of the kiln itself, the material is required to undergo thorough chemical and thermal analyses.
Rotary Kilns. For over 40 years we have performed work in many different types of kilns and related systems for customers throughout the United States.

· Rotary kiln design is a complex process, with a variety of factors and material characteristics influencing the sizing and design. This presentation gives an overview of the sizing and design process, including the many factors that will need to be considered during the design stage.
The kiln model applied in this work was developed by Hatch over a number of years and has been used for several rotary kiln projects. It has its roots in a FORTRAN program that was developed by Venkateswaran (1978) to study the reduction of iron ore. The original software was used to model the operation of a 35 m pilot kiln at the Stellco company
