cement production process

Cement - Wikipedia
A cement is a binder, a chemical substance used for construction that sets, hardens, and adheres to other materials to bind them together. Cement is seldom used on its own, but rather to bind sand and gravel (aggregate) together. Cement mixed with fine aggregate produces mortar for masonry, or with sand and gravel, produces concrete. Concrete is the most widely used material in existe

They are mixed either dry (dry mixing) or by water (wet mixing). 3) Prepared raw mix is fed into the rotary kiln. 4) As the materials pass through the kiln their temperature is rised upto 1300-1600 °C. The process of heating is named as “burning”. The output is known as “clinker” which is 0.15-5 cm in diameter.

Cement production process : step by step, carbon footprint
The use of fossil fuels such as coal, natural gas, and oil is common in cement production, both as a fuel for the kiln and as a source of heat for other parts of the process which leads to CO2 emitted by combustion.However chemical reactions happening in the kiln (calcination) are also responsible for up to 60% of the total of emissions of the cement
