The Homogenizing and stability of cement product are important index for the production of cement. However, the homogenizing and stability of cement depend on stability and homogenizing of raw materials, raw meal and clinker in the process of production. H = sigma_(in)/ sigma_(out) is used to express the improving extent of homogenizing of batch (homogenizing coefficient). where sigma is a standard deviation (SD) for homogenizing and stability. sigma indicates extent of homogenizing and stability, which affects the technical decision made by the technicians; while H indicates homogenizing coefficient (HC) of a homogenize system, which affects the selection for a homogenize system. If the decision is made incorrectly, it will lead to the mass waste for the investment of or the instability of production. Nevertheless, can it be described correctly the practical situation using the statistical standard deviation and homogenizing coefficient?
