Rotary kiln stable chemical reaction required

In order to ensure good fuel combustion and heat transfer conditions Rotary kiln system, thus the best thermal stability of the system to ensure the Rotary kiln system in the production of the chemical composition of the raw material must be stable, steady volume of feed raw materials, fuel composition (including calorific value, fineness of coal, oil atomization, etc.) stable, the amount of fuel feeding device stability and stable operation. General chemical reaction, either the uniform mixing between the reactants, close contact; second is required to create a chemical reaction requires the objective environment (such as: temperature, pressure, catalyst, etc.), to accelerate the reaction rate.The industrial production of cement raw material ingredients, grinding and homogenizing processes, is to make the chemical composition of the raw material with a predetermined, increasing the surface area of ​​the reactants, so that uniform mixing to achieve close contact with the cement for the chemical reaction between points to create conditions; firing process is a chemical reaction to form the necessary environment needed to supply the endothermic reaction heat and the temperature field and accelerate the rate of reaction.
