Generally on cement mills, the product is ground dry in a ball mill. It has a relatively wider particle size distribution; hence, it is required to operate the ball mill in a closed circuit with a size classifier with an efficient or sharp cut of the size separator. This happens especially when high levels of fines are generated, when mixtures ...

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.
