Fig of Thermal Energy use by different fuels Thermal SEC From the above pie chart, it is clear that the indian coal has a maximum share (%; Mkcals)in the overall cement plant's total thermal energy use and Imported coal constitutes % ()followed by minimum contribution by both the liquid fuels.
2 ENERGY USE IN CEMENT MANUFACTURING. Cement manufacturing is an energyintensive process that consumed more than 61 000 terajoules of energy in Canada in 2006, of which 95 percent was thermal energy and 5 percent was electric energy. The kiln process consumes more than 90 percent of the cement manufacturing energy.
The cement grinding station uses precrushing technology, so that it reduces the granularity of the materials that are fed into the grinding mill, and on the other hand, promotes the materials to produce flaws and defects inside, thus greatly improving the output of .
The majority of CO 2 produced during cement manufacture arises during clinker production, due to the calcination of calcium carbonate, fossil fuel burning and electricity consumption (mostly for grinding).

Concrete steps towards profitability, In terms of grinding of raw materials, fuels and cement grinding ball mills are now considered to be outdated technology, especially when considering their electricity consumption While the specific energy consumption of. cement grinding especially tapetenversandeu
The hardness, toughness, dissociation and structural defects of the raw ore determine the difficulty of grinding. If the grinding degree is small, the ore is easy to grind, and the smaller the wear of mill liner and steel ball is, the smaller the energy consumption is; on the contrary, the opposite is true.

the specific energy consumption by per cent. In this example, the annual CO 2 emission derived from electrical energy used for the cement grinding process accounts to per cent of the total CO 21). As a consequence, CO emission. Therefore, the effect of the reduced electric energy consumption on total CO 2 emission is only very limited
The power ingesting of a grinding process is 5060% in the cement production power consumption. The Vertical Roller Mill (VRM) reduces the power consumption for cement grinding approximately 3040% associated with other grinding mills.
