Cement grinding are used to improve the efficiency of cement production and reduce energy consumption. Cement grinding have been used for improving cement clinker grinding efficiency, power flow ability, and strength development of binders.
The cement industry in India is probably the most efficient in the world and has a well deserved reputation for technology upgradation. The proper selection of plant and machinery, and process systems and auxiliary equipment is not only important from the energy efficiency point of view, but also critical from the plants.
India is the second largest producer of cement in the world. No wonder, India's cement industry is a vital part of its economy, providing employment to more than a million people, directly or indirectly. Ever since it was deregulated in 1982, the Indian cement industry has attracted huge investments, both from Indian as well as foreign investors.
India has a lot of potential for development in the infrastructure and construction sector and the cement sector is expected to largely benefit from it. Some of the recent major initiatives such as development of 98 smart cities are expected to provide a major boost to the sector.
Cement production capacity stood at 502 million tonnes per year (mtpy) in 2018. Cement consumption is expected to grow by 4.5 per cent in FY19 supported by pick-up in the housing segment and higher infrastructure spending. The industry is currently producing 280 MT for meetings its domestic demand and 5 MT for exports requirement.
The Indian cement industry is dominated by a few companies. The top 20 cement companies account for almost 70 per cent of the total cement production of the country. A total of 210 large cement plants account for a cumulative installed capacity of over 350 million tonnes, with 350 small plants accounting for the rest. Of these 210 large cement plants, 77 are located in the states of Andhra Pradesh, Rajasthan and Tamil Nadu.
