Clinker cooling is the final step in clinker production. This process aims to recycle heat, preheat the secondary air, and improve the quality and grindability of the clinker.

2011-7-1 Energy demand in clinker production has been significantly reduced over the last few decades. Best available techniques (BAT) levels for new plants and major upgrades are 2900 to 3300 MJ/t clinker, based on dry process kilns with multistage-preheaters and precalciners .However, the factors involved to further reduce this demand are plant-specific.
