Heat exchange in a rotary kiln may be by conduction, convection and radiation, in descending order of efficiency. In low-temperature processes, and in the cooler parts of long kilns lacking preheaters, the kiln is often furnished with internal heat exchangers to encourage heat exchange between the …


Defining your desired reaction will not only determine what needs to happen inside of the rotary kiln, but it will also have a lot of input as to what components will make up the rotary kiln's design.


Design features of rotary cement kilns. The shell of the kiln is made of mild steel plate. Mild steel is the only viable material for the purpose, but presents the problem that the maximum temperature of the feed inside the kiln is over 1400°C, while the gas temperatures reach 1900°C.
