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.
Clinker size and cement grinding. Clinker size is important for the optimization of cement grinding, and is also an indicator of cement quality. Having a high percentage of coarse clinker can be difficult to grind. However, having a high percentage of fine clinker can also be hard to grind and have a negative impact on cement performance.

However, increasing the SCM level to lower the clinker factor usually results in somewhat poorer cement performance. For example, a 1% increase in SCM can reduce 28-day mortar strength by 0.2 - 0.8MPa, depending on SCM type, cement fineness, grinding system, and clinker characteristics. The impact on strength can be mitigated …
The cover story captures the journey of an age-old system of grinding to the present one. It covers from mill internals to the use of grinding aids. A cement clinker is usually ground using a ball mill. This hardware is generally divided into two or three chambers, with different size of grinding media. As the […]
