    While it may seem obvious that the chemical composition of a material is an important factor in any processing operation it is especially critical when working with rotary kilns as rotary kilns are used to carry out chemical reactions and phase changes the chemical composition of a material serves as the foundation of the design process apart from knowing the parameters of the intended reaction a
