How Can Rationally Adjust the Temperature inside Cement Kiln?

The circumgyrate cement kiln with high fineness and high yield is mainly used in open-circuit powder grinding system and it has such features as simple system equipment and technical process, lower investment and smaller floor space of the work plants. The structure of the grinding mill adopts advanced internal powder separation cabin partition device, greatly improving the powder grinding efficiency and reaching the goal of high output and low energy consumption. In the cement drying operation, we will encounter problems caused by the temperature instability. Because of the instability of temperature of the cement rotary kiln, it will be difficult to control calcination and cause a series of problems, such as product quality. When the temperature of cement rotary kiln is high or low, the material will be bad or good to be for preheating, and calcination is difficult to control. When material presintering after complete reaction is to the calcining zone, material layer becomes thinner and is easy to burn, to stabilize the firing temperature, must reduce coal. When presintering material after the incomplete reaction is to the calcining zone, after the material layer changes, it will be difficult to burn, this time will be to force in order to improve the temperature calcination, even play slow kiln, ruined the thermal system of the rotary kiln speed instability, rapid rate is low, a direct impact on the yield and quality. So from the process of materials into the kiln to burn mature material, the speed of material change and the quality of the reaction are directly related to the level of temperature. Rotary kiln changes according to certain rule, so the cement rotary kiln in the process of decomposition, sintering process, such as preheating, we will strictly control the temperature in the range of 5 ~ 10 degrees, in order to ensure high quality and high yield of rotary kiln, stable thermal, normal calcination, uniform material preheat, and complete reaction. crusher equipment: http://www.china-mills.com/
