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 locally-available raw materials which make up the bulk of the raw meal.
the cement manufacturing. In our previous works we have designed high strength Portland cement  and sulfate resisting cement  from the raw material of the study area which meet the British standard specifications and the area has been declared feasible for the installation of cement plants, manufacturing both these cements.

Stage of Cement Manufacture. There are six main stages of cement manufacturing process. Stage 1 Raw Material Extraction/Quarry. The raw cement ingredients needed for cement production are limestone (calcium), sand and clay (silicon, aluminum, iron), shale, fly ash, mill scale and bauxite. The ore rocks are quarried and crushed to smaller pieces of about 6 inches.

Cement consumption is dependent on the time of year and prevalent weather conditions. Nearly two-thirds of U.S. cement consumption occurs in the six months between May and October. The seasonal nature of the industry can result in large swings in cement and clinker (unfinished raw material) inventories at cement plants over the course of a year.

Mills belong to a class of equipments that accomplish comminution of materials in the fine range. There are two types of mills which are mostly used in cement plants for grinding raw mix viz. Ball mills and VRM. Ball mills Ball mills are essentially fine grinding units capable of grinding material to a fineness say 84% passing 90 microns.
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.
Aug 30, 2012 There are also various other raw materials used for cement manufacturing. For example shale, fly ash, mill scale and bauxite. These raw materials are directly brought from other sources because of small requirements. Before transportation of raw materials to the cement plant, large size rocks are crushed into smaller size rocks with the help of ...
The cement manufacturing plant can be divided into five steps: Crushing & prehomogenization: cement crusher crush limestone and other materials and stacker and reclaimer homogenize them.; Raw material preparation: use cement mill to process materials into required sizes for cement clinker production.; Clinker production: In the cyclone preheater system, the raw material powder exchange heat ...

Aug 01, 1987 Cement manufacturing process is now operated with the aid of various control systems, such as raw meal compositi on control, kiln control and mill control. Those systems have greatly contributed to achieve uniformity of quality as well as cost re duction of cement.
cement industry has been using large quantities of waste fuels or biomass fuels, for more than 15 years. The production of cement involves the consumption of large quantities of raw materials, energy, and heat. Cement production also results in the release of a significant amount of solid waste materials and gaseous emissions.
