Better and cheaper cement: Optimising the right 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.

Cracking the Code: The Mystery Behind Why Clinker is Hard …

Moreover, utilizing specialized grinding techniques, such as pre-grinding or inter-grinding additives, can further enhance the grindability of clinker. Pre-grinding involves crushing the clinker before it enters the mill, while inter-grinding additives are blended with the clinker during the grinding process to reduce particle agglomeration …
