Cement kiln - Wikipedia
Tricalcium silicate is thermodynamically unstable below 1250 °C, but can be preserved in a metastable state at room temperature by fast cooling: on slow cooling it tends to revert to belite (Ca 2 SiO 4) and CaO. If the reaction is incomplete, excessive amounts of free calcium oxide remain in the clinker. Regular measurement of the free CaO ...

The rate of cooling is critical to the clinker quality and the performance of the subsequent cement. Rapid cooling is desirable. Slow cooling of the clinker will tend to produce a coarse-grained clinker microstructure with large alite and belite crystals, resulting in poor grindability and poor reactivity, having a negative impact on strength.

cooling rate of the clinker. The highest temperature form, α, can contain several percent of Al 2 O 3, Fe 2 O 3 and alkali. However, the lower temperature forms, α' and β, can only hold a small amount. •On cooling and phase change, therefore, the impurities are exsolved and cause a clouding of the crystals.
Clinker Cooler - Metallurgist & Mineral Processing Engineer
The capture of secondary combustion air above the cooling clinker was a big forward step in achieving better rotary kiln economy and fuel utilization. Besides fuel savings, clinker grinding costs were substantially reduced. In many cases it was found that a quick-quench clinker was much easier to grind.
