During the operation of a rotary kiln, the lining refractories wear out. Usually, its thickness decreases from the initial 230 mm to 80 mm. It is valuable to simulate the possibility of refractory destruction when its length changes to 230, 180, 150, 120, and 80 mm. The calculation results are shown in Fig. 11.

Overview. Thermopower Furnaces is a specialist of custom designed rotary kilns. Rotary kilns are typically run at significantly higher temperatures when compared to rotary dryers. Rotary Kilns drive a physical or chemical change to the processed material which may require either oxidizing, reducing or inert gas atmospheres within the rotary tube.
DetailsWhen heating the rotary kiln, the synthetic resin loses its adhesiveness between 100 and 400°C; thusthe thermal expansion of the lining is not impaired by the epoxied briks. Examples for rotary kiln lining. In the United States, a 4.85 x 75 m preheater kiln is lined with refractory as follows; it is measured from the kiln's discharge end.
