Methods to improve the thermal efficiency of the cement Rotary kiln

Article source：

Cement Rotary kiln it is to reduce the moisture materials into the Rotary kiln, dry process is to increase the area of ​​materials and hot air, so as to improve the thermal efficiency of the device. Thermal efficiency of wet cement Rotary kiln reason is not high, because the water contains more wet slurry, the water tends to remove these consume a large amount of heat.The dry process cement Rotary kiln materials although less water, but not the heat transfer area, the thermal efficiency is also not high.Theoretically speaking to spend more than 1700 kJ of heat, but due to various reasons, the operation is often much more calories consumed.So on this fact in writing and the ratio of the heat demand, it is called the thermal efficiency of the cement Rotary kiln.
