Limestone plays two major roles in the cement manufacturing process, one is used as a raw material for cement clinker, and the other is used as a cement admixture. Limestone is one of the key raw materials of cement clinker. Around 80-90% of the raw material for the kiln feed is limestone.
Evaporation of volatiles Volatile phases in the cement kiln are principally alkali sulfates, with a much smaller proportion of alkali chlorides. As the part-burned feed approaches the burning zone, these volatile phases are in liquid form and a proportion volatilizes, the remainder passing out of the kiln in the clinker as inclusions within the ...

It plays an important role in the cement clinker production process and directly affects the cement product quality. 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.
Large clinker nodules (Figure 2) are difficult to cool, transport and grind into cement. Clinker should ideally have a smaller average nodule size and a narrow nodule size range. More uniformly sized clinker is more evenly distributed into the cooler and has more consistent bed porosity, which enables more stable cooler and kiln operation.
