The Clinker Cooling Process. Grate coolers are commonly used to cool clinker. To speed up the process, cool air blows against the clinker flow into the material layer. The cool air is from the lower portion of the bed to bring the temperature of the clinker down. The hot air that results from this process is then used for burning fuel.

From the cement raw material entering the production process to the clinker being sent out of the clinker cooler, it takes about 55 min, of which about 23 min are spent on the calcination of the clinker and 28 min are spent on the cooling of the clinker [37]. The final clinker can be cooled to about 225.0 °C [38].
