Cement Production Process | Cement Manufacturing Process
There are three steps of the high-temperature system: Drying or preheating, calcining, and sintering. The calcining is the core part of the clinker production; the raw meal is weighed and sent into preheater and cement kiln to process clinker. Grate cooler helps to cooler clinker, the cooled clinker is sent to the cement silo for storage.

Cement manufacturing process: Step-by-step guide
Cement manufacturing process in summary Portland cement is manufactured by heating limestone (calcium carbonate) with other materials (such as clay) to 1,450 °C (2,640 °F) in a kiln, in a process known as calcination that liberates a molecule of carbon dioxide from the calcium carbonate to form calcium oxide, or quicklime.

The model is used to optimise process control and the use of alternative fuels while maintaining clinker product quality. It is also used to predict the possible changes in the combustion, precalcining and clinker formation processes. The waste tyre fuel for example also acts as a raw material in the clinker manufacturing process.
