Indian cement: An overview
India had an installed cement capacity of 595Mt/yr at the end of FY2023, with around 80 producers operating 300 cement facilities. Of these, 170 are integrated, and 130 are grinding plants, blending units and terminals. However, the top 25% of producers - either major Indian producers or regional players - hold about 85% of the total capacity.
CEMENT GRINDING SYSTEMS
The final manufacturing stage at a cement plant is the grinding of cement clinker from the kiln, mixed with 4-5% gypsum and possible additives, into the final product, cement . In a modern cement plant the total consumption of electrical energy is about 100 kWh/t . The cement grinding process accounts for approx. 40% if this energy consumption.
