It imparts resistance to chemical attack. Rising of C2S content renders clinker harder to grind, reduces early strength, decreases resistance to freezing and thawing at early ages and decreases the heat of hydration. The hydrolysis of C2S proceeds slowly. At early ages, less than a month, C 2S has little influence on strength and hardness.

 · The evaluation of grinding aid (GA) effect on clinker processing in laboratory grinding mills is relatively simple. Yet, the results obtained cannot be directly transposed to industrial mills, given the fundamentally different operational modes and grinding parameters. This paper seeks to evaluate the scale effect by comparing the results …

 · As a general rule, there should be less than 25% of clinker that is below 1mm in size. Coarse clinker is more of an issue for ball mills. Some cement groups use a formula, such as Bond's, to calculate the maximum ball size required in a ball mill, based on the average size of the clinker feed. However, one drawback with this approach is that ...

Toute la chaux ne peut être saturée et reste sous la forme de chaux non combinée ou chaux libre. La chaux libre est un paramètre essentiel pour juger de la qualité et du degré de cuisson du clinker. Des clinkers bien cuits résultants d'un cru bien dosé et de bonne granulométrie présentent des teneurs inférieures à 2 %.

 · The cement clinker material is crushed by the crusher to the fineness (15mm-50mm) that can enter the mill. The second stage: milling. The crushed small pieces of cement clinker are sent to the storage hopper by the elevator, and then sent to the grinding chamber of the mill evenly and quantitatively by the feeder for grinding.

 · Clinker grinding technology is the most energy-intensive process in cement manufacturing. Traditionally, it was treated as "low on technology" and "high on energy" as grinding circuits use more than 60 per cent of total energy consumed and account for most of the manufacturing cost. Since the increasing energy cost started burning the benefits …
