Typically, 60% of burned calciner and more than 90% calcination have been reached before the material enters the rotary kiln. Inside the kiln, temperatures reach approximately 1400°C to complete the process of chemical reactions and producecalcium silicates, calledclinkers, with adiameter of 10–25 mm.

However, new cement kilns are of the 'dry process' type. Dry process kilns. In a modern works, the blended raw material enters the kiln via the pre-heater tower. Here,hot gases from the kiln, andprobably the cooled clinker at the far end of the kiln, are used to heat the raw meal. As a result, the raw meal is already hot before it enters the kiln.

A series ofchemical reactionsof calcium, silicon, alumina and iron oxides present leads to the formation of the clinker material with main compounds tricalcium silicate (C 3 S), dicalcium silicate (C 2 S), tricalcium aluminate (C 3 A) and tetracalcium aluminoferrite (C 4 AF). After cooling and storage, the clinker is ground into a finecement...

Cementused in construction is characterized as hydraulic or non-hydraulic. Hydraulic cements (e.g., Portlandcement) harden because of hydrationchemical reactionsthat occur independently of the mixture's water content; they can harden even underwater or when constantly exposed to wet weather.
