Influence of temperature of raw material into rotary kiln ...

2020-1-22 · The residual decomposition reaction of calcium carbonate and the process of slow rise in material temperature in rotary kilns remain a bottleneck, which limits the growth in kiln capacity and reduction in energy consumption. Some researchers have put forward the idea of increasing the temperature of the raw material entering the rotary kiln.

2021-10-28 · The makeup of a kiln. During the operation of the rotary kiln, flames can reach temperatures as high as 1900°C (3452°F) in order to heat raw materials to roughly 1500°C (2732°F). As a result, these materials become partially molten and undergo a series of physical and chemical reactions to become the primary constituent of cement.

Computation and Measurement of Material Temperature

In the present study material temperature is computed on the basis of (i) well mixed theory i.e., tumbling is assumed to occur during operation of the kiln (ii) non-mixed theory i.e., tumbling is assumed not to occur during operation of the kiln. The experimental material temperature is compared with the computed material temperatures on the ...
