Keep ReadingThe hardest clinker takes about 80% more power than the softest one . Furthermore, different fineness requirements result in higher energy consumption. Clinker grindability is the measure of the ability of a clinker to resist grinding forces. It is used to estimate the energy requirement for grinding the clinker to a given fineness.
