The main raw materials used are limestone, sand, shale, clay, and iron ore. The manufacturing process is highly energy intensive. Major players in the Indian cement …
Cement manufacturing is a complex process that begins with mining and then grinding raw materials that include limestone and clay, to a fine powder, called raw meal, which is then heated to a sintering temperature as high as 1450 °C in a cement kiln. In this process, the chemical bonds of the raw materials are broken down and then they …
Cement - Extraction, Processing, Manufacturing: Raw materials employed in the manufacture of cement are extracted by quarrying in the case of hard rocks such as limestones, slates, and some shales, with the aid of blasting when necessary. Some deposits are mined by underground methods. Softer rocks such as chalk and clay can be …
The utilisation of alternative fuels in cement kilns started in Year 2000 with the active support of the Central Pollution Control Board. With persistent efforts of the cement industry, Government of India and other stakeholders, the Thermal Substitution Rate (TSR) has now increased to ~5 per cent as compared to 0.6 per cent in 2010.
