    The grinding process impacts the cement manufacture in at least two ways. First an increase of the fineness and homogeneity of the raw mix accelerates the clinkering reactions leading to less variability of the clinker due to the enhanced stability of the kiln and better energy efficiency in producing a clinker of better consistency.
