Cement Production Process | Cement Manufacturing Process | AGICO CEMENT
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.

Most organic materials have a caloric content of 9-16 GJ/ton cement, while the main firing of a cement kiln requires at least 18-20 GJ/ton cement. Thus, biomass would have to blend with other fuels if used in the kiln. The lower process temperatures in the precalciner allow the use of lower caloric value fuels.
