Cement production in the world is currently about 1.6 billion ton per year. About 2% of the electricity produced in the whole world is used during the grinding process of raw materials .While total electrical energy consumption for cement production is about 100 kWh/ton of cement, roughly two thirds are used for particle size reduction .About 65% of the total electrical energy used in a cement

Raw materials are extracted from the quarry and by means of conveyor belt material is transported to the cement plant. 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.

Cement manufacturing is a complex and energy-intensive process. A key stage in this process is the conversion of ground raw materials (CaCO 3, clay and/or shale) into clinker (synthetic cementitious minerals) in the kiln. A typical operation uses kiln exhaust gases to preheat the raw materials before they enter the kiln. Further

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.

Mill designs. The most important first step in controlling energy consumption is to be aware of the relative importance of the process areas where most energy is consumed. Figure 2 shows a typical breakdown of electrical energy consumption at a cement plant. The most obvious area for attention is that of grinding, both raw and cement.
