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.
The heart of the portland cement manufacturing process is the pyroprocessing system. This system transforms the raw mix into clinkers, which are gray, glass-hard, spherically shaped nodules that range from 0.32 to 5.1 centimeters (cm) (0.125 to 2.0 inches [in.]) in diameter.
