What is Mixing, Blending? "Mixing is the process of thoroughly combining different materials to produce a homogenous product." The mixture is generally a combination of dissimilar materials, coal ash and cement are blended in a specified ratio to produce Pozzocrete cement.
Technically, a cement producer can have almost complete control over clinker composition by blending raw materials of different compositions to produce the desired result. In practice, however, clinker composition is largely determined by the compositions of the locallyavailable raw materials which make up the bulk of the raw meal.

The raw mix is fed into a circular storage unit called a raw mix storage. Then, the mix is extracted transversely from the stockpile by reclaimers and conveyed to a raw mill bin called the raw mix bin for grinding. The other raw materials that are used in cement manufacturing, called additives, are high purity limestone, sand and iron ore.
Raw Material DryingGrinding cement plant optimization Ball Mill Ball mills with high efficiency separators have been used for raw material and cement grinding in cement plants all these years. Ball mill is a cylinder rotating at about 7080% of critical speed on two trunnions in white metal bearings or slide shoe bearings for large capacity mills.

Methods of Manufacturing Process of Cement. At present Portland Cement is manufactured by two processes, Dry Process, and Wet Process. The main difference between these two methods of manufacturing of cement is that in the dry process, calcareous and argillaceous raw materials are fed into the burning kilns in a perfectly dry state.
Cement Extraction and processing Britannica. There are four stages in the manufacture of portland cement: (1) crushing and grinding the raw materials, (2) blending the materials in the correct proportions, (3) burning the prepared mix in a kiln, and (4) grinding the burned product, known as "clinker," together with some 5 percent of gypsum (to control the time of set of the cement).
