This is called clinker The hot clinker next falls into a cooler which recovers most of its heat and cools the clinker to around 100 176C at which temperature it can be conveniently conveyed to storage The cement kiln system is designed to accomplish these processes Early history
Cooling kiln protects equipment and facilitates quenching the clinker to ensure the important forms of minerals like C3S C2S C3A C4AF stay in it so that proper clinker quality is maintained Improper design of cooling fans can lead to poor clinker quality high power consumption and even damage of the conveying system
The cooling of cement is an important step prior to storage in mitigating gypsum dehydration and subsequent moisture liberation which can lead to lump formation Recommendations vary but it is generally accepted that with mill outlet temperatures of around 110ºC – 120ºC cooling to below 80ºC is necessary to avoid this reaction
