The early commercially successful rotary kilns in Britain were nearly all "straight" cylinders, the exceptions being those at Norman (1904). Lengthening of the early kilns at Wouldham and Bevans resulted in kilns with enlarged burning zones, while the lengthened kilns at Swanscombe had enlargements at both ends. Among new installations from 1909 to 1914, only 15 out of 44 …

The main design of a rotary kiln is rather simple – consisting of a cylindrical steel casing and one or several layers of refractories in order to protect the casing from high service temperatures. The dimensions of a rotary kiln vary between some 10 to 180 m in length and 2 to 8 m in diameter. ...
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
