Rotary kiln belongs to building materials equipment category, mainly used for calcination of cement clinker, but also for the production of refractory materials such as calcination of clay, limestone and slag drying. The rotary kiln has simple structure, convenient and reliable production process control, few vulnerable parts, and high operation rate. It is a necessary equipment for cement plant calcination. It is also widely used in metallurgy, chemical industry, construction and other industries. Our company customizes and designs various large, medium and small rotary kilns according to the different needs of customers. During the application process, it runs smoothly and has high efficiency...Learn More

Chemical reactions take place inside the rotary kiln the cross section of the rotary kiln is at fig 1 fig 1 cross section of rotary kiln coal based direct reduction process is based on the solid reducing agent which is noncoking coal
Chemical compositionknowing the chemical composition of a material is a diagram tga analysis for a sample valuable asset in rotary kiln design for several reasonsone important reason is that many materials will combust inside the rotary kiln at high temperatures creating more heat than was put into the rotary kilnin cases such as these the rotary kiln will need to be designed to withstand those
When dealing with gassolidreactionsinrotary kilns it is necessary to realize that the total particle surface within the granular bed can be much larger than the outer surface of the bed depending on thereactionconditions this inner surface can contribute considerably to thechemicalconversion in thekiln
