    The efficiency of the early stages of grinding in a ball mill is much greater than that for formation of ultrafine particles, so ball mills operate most efficiently by making a coarse product, the fine fractions of this then being separated, and the coarse part being returned to the mill inlet The proportion of the millexit material returned to the inlet may vary from 1030% when ordinary14/08/2020· C3S in Clinker Raw mix design Choice of clinker mineral phases always go with high C 3 S value because this is the main active component in clinker, which has high hydration rate and is the responsible in early strength developments in cement The preferred range may go as high as 60 % with 15–17 % C 2 S presenceC3S in Clinker Raw mix design | by ASen | Medium
