USA ABSTRACT The effect of chemical and mineralogical composition of raw materials mixture and all kinds of raw materials). The stability of raw material composition is the premise of clinker burning system.The chemical and mineralogical compositions of the by-products and raw materials were determined. Homogeneous raw mixes containing different concentrations of by-products (5--30%) were prepared and the influence of the by-products on all steps of burning the mixes in a kiln to form a cement clinker was investigated.Therefore the chemical composition of cement raw materials and clinker are critical to cement plant efficiency and energy consumption. However in order to ensure constant and consistent chemical compositions and quality of cement clinker with lowest possible energy consumption,
