As one of rotary kilns, cement rotary kiln from HANDA Heavy Industry has been widely used to process cements and lime. In the production of cement, this kind of rotary kilns is the dedicated device that can calcine the cement raw material at high-temperature. That’s to say, cement rotary kiln has been the most important equipment in cement production process, as well as cement ball mill. During the operation, there may be some problems impacting on the product quality, so today, HANDA Heavy Industry, a leading professional heavy industrial machinery designer and maker, can list some common problems and solutions as follows. Please correct if any deficiency in the passage.
In sum, there are three aspects about the common problems in cement rotary kiln working process, including that the temperature of burning zone is too high or too low; the oxygen gas content in the kiln tail is too high or to low and the temperature of kiln tail is too high or too low. Sometimes these three problems show individually or two by two, while sometimes problems show from all three directions. Actually, these questions should be treated as a whole, and operators should adopt corresponding strategy to different problems, or even take different measures to different degrees at a same problem.
For example, in cement rotary kiln production process, when the temperature of burning zone is low, the oxygen gas content of kiln tail is low and the temperature of kiln tail is also low (3 problems show together), operators need to reduce the speed of kiln to improve the temperature of burning zone and kiln tail, and at the same time decrease the coal feeding to enhance the oxygen gas content of cement rotary kiln tail. However, when the temperature of burning zone is a little low, users need to increase the revolving speed of high temperature fan and add the coal feeding in order to promote the burning zone temp and oxygen gas content of kiln tail.
Finally in a word, according to these problems existing in the burning zone temp, oxygen gas content of cement rotary kiln tail and kiln tail temperature, HANDA Heavy Industry suggests to take measures from kiln speed, coal feeding and high temperature fan for solutions.
