rotary kilns are designed to withstand much higher temperatures than a rotary dryer. typically if you are dealing with a direct fired rotary kiln it is refractory lined with a brick or castable lining. this lining protects the steel shell. rotary dryers are typically not lined and their steel is not able to withstand such high temperatures.

the tyre not only facilitates the rotary motion of the kiln but is also responsible for maintaining its roundness and consequently the mechanical integrity of refractory. the shell at the points of support would collapse were it not for the girdling effect of the tyre.
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 shell diameter at normal operating temperature.
