Clinker Cooler
Clinker leaves the cement kiln usually at more than 1200℃ and it carries a heat content of about 1250-1650 kJ/kg. So it needs to be cooled to: improve the cement quality and the grindability of clinker. When the clinker is rapidly cooled, the formation of mineral crystals in it is inhibited. Even if some of them have crystallized, they are ...
