rotary kiln temperature control

Rotary Kiln Temperature Control. Rotary kilns (or rotary dryers) are used extensively in industry for drying solids. They consist basically of a large metal tube which is rotated while hot air and wet solids are fed into it. Both co-current and counter-current configurations are used

    Nov 28, 2019 Lime rotary kiln is different from other rotary kilns because it has a preheat bin. Before limestone even come in a rotary kiln, the temperature of the preheating bin has arrived at 1150℃. Meanwhile, limestone will be put into the preheat bin through a bucket elevator and be heated to 900℃

    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

    All rotary kilns must be equipped with exhaust or flue gas handling equipment, sometimes referred to as a gas conditioning system. This system collects and treats (or “conditions”) any products of combustion, loss on ignition, gaseous emissions, and small particulates leaving the kiln in order to prevent air pollution and control

    This can be done by picking a spot on the rotary kiln shell, and holding a temperature gun in place. As the rotary kiln rotates, that spot should read the same temperature for the entire circumference of the shell. For example, a temperature reading of 400 , 400 , 700 , 400 would likely indicate a failure in refractory
