Analysis about Chemical Changes in the Rotary Kiln

When the rotary kiln is started, we can adjust the velocity of flow in the rotary kiln to increase the temperature of the kiln end. In addition, the amount of fuel can be regulated to increase the temperature of the burning zone. We can make full use of the regulation of the combustion air (oxygen) to gradually increase the rotating speed and yield of the rotary kiln. The adjustment of the combustion air adjustment will help the manipulation of the rotary kiln. When the temperature of the kiln end decreases, you can not accelerate the rotational speed of the rotary kiln. The rotational speed can be accelerated only when the temperature rises. In the case of a light load, increase the rotational speed of the rotary kiln. After the balance of all the parameters, increase the load of the rotary kiln. It is easy to improve the rotational speed of the rotary kiln under the light load.
When the system of the rotary kiln is in a serious disorder, reducing the load of the rotary kiln helps calibrate its work system. After the disturbances are quelled, gradually increase the load of the rotary kiln. The work system of the rotary kiln can be corrected by reducing the rotational speed without reducing its load. After the disturbances are removed, gradually increase the speed of the rotary kiln and increasing the combustion air, which can raise the temperature of the kiln inlet to make it easier to correct the rotary kiln. Maintain the filling amount of clinker kiln in the firing zone which can protect the skin of the kiln. However, you can not always fix the materials in one place. Try to do changes as small as possible after you have understood the problems. Only change a parameter at the right time can you achieve satisfactory results. Changing the temperature of the secondary air can make the increase or decrease the temperature of the burning zone. If the temperature of the secondary air is too high, it may affect the kiln skin. In the calcining process in the kiln of the materials, the carbonate of the magnesium and calcium discomposes and the moisture in the kaolin evaporates.
