Lime rotary kiln is large-scale calcining equipment, generally through electricity, coal or natural gas, etc., to make the temperature inside the kiln reach the specified value, increase the decomposition rate of calcium carbonate, so as to complete the lime calcination work. The temperature inside the kiln directly determines the quality of lime produced, especially the control of the temperature at the end of the kiln, we must pay attention!
Under ideal conditions, there is an ideal kiln end temperature for different kiln speeds and feed rates of the rotary kiln, which will ensure proper calcination. If too much heat flows to the rear of the kiln, the kiln charge will unnecessarily break down completely prematurely and clinker formation will move towards the rear of the kiln. Too much heat to the rear of the kiln after firing the zone means poor operating efficiency and, as a result, wasted fuel. Conversely, not having enough heat to the rear of the kiln can create undesirable conditions, causing operational difficulties when the material is not fully distributed as it enters the firing zone.

The exhaust fan speed and fuel volume are often the cause of kiln tail temperature variations. If the speed of the exhaust fan is increased, the amount of fuel is increased or the amount of feed is decreased, the result will increase the temperature at the kiln end; on the contrary, the temperature at the end of the kiln will be reduced due to the decrease of the speed of the exhaust fan, the decrease of the fuel amount or the increase of the amount of feed, etc.
It can be seen from this that it is very important for the temperature in the lime rotary kiln to be stable. As a professional rotary kiln manufacturer, Xinxiang Great Wall Machinery recommends that in order to ensure the efficient operation of the equipment, users can measure the temperature through remote control, install a digital display in the equipment, and then convert the temperature to the digital display, so as to better grasp the inside of the kiln. The abnormal temperature is adjusted in time, which not only achieves the purpose of high output and high quality of the equipment, but also effectively prolongs the service life of the equipment!
