In addition, CSA clinker is easier to grind than OPC [15]. In cement manufacturing, 30–40% of electricity consumption is used for the final cement clinker grinding [1], [3], [4]. It is noteworthy that grinding is a low-efficiency process. Less than 5% of the energy is used for the increase of cement surface area, while more than 95% of …

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.
