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 are ...

The cement manufacturing process is completed when the cooled clinker is ground once again in a rotating finishing mill. A combination of gypsum and limestone will usually be added in small amounts to the heated cement during this last grinding step, and coloring agents can also be added here. The fineness of the finished particles will vary according to individual preferences, and the cement ...

Cement production is a thermal energy intensive process, which requires heating solid particles up to 1450°C and cooling it down. The process generates hot and CO 2 rich exhaust streams. Fin order to study energy efficiency of the process, authors like Mujumdar et al. (2006, 2007) developed detail models of process units, while others ...

Methods of Manufacturing Process of Cement. At present Portland Cement is manufactured by two processes, Dry Process, and Wet Process. The main difference between these two methods of manufacturing of cement is that in the dry process, calcareous and argillaceous raw materials are fed into the burning kilns in a perfectly dry state.

This process accounts for ~50 percent of all emissions from cement production. Indirect emissions are produced by burning fossil fuels to heat the kiln. Kilns are usually heated by coal, natural gas, or oil, and the combustion of these fuels produces additional CO 2 emissions, just as they would in producing electricity.
