Optimising clinker PSD. Any type of cooler will work more effectively when it is fed with correctly-sized clinker nodules. 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 ...
