If raw material fineness is too coarse, it will affect the firing of the clinker. If the fineness exceeds the fine rules, the mill output will decrease and the power cent result of the raw material fineness per hour according to the laboratory. The speed of the separator is such that the fineness is controlled within the range of R 0.08≤14~16%.

Higher fineness also implicates a lower production rate. Each 100cm²/g more specific surface according to Blaine reduces the cement production rate by approximately 3-4 per cent6. As already described, grinding aids can compensate a loss of production and thus contribute to achieving the desired fineness in the most economical way.
