rotary kiln temperature detection in pellet plant in the

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
