There are numerous studies that had discussed the importance of the shape of the size distribution. In the field of cement manufacturing, Kuhlmann et al. (1985) reported that for the same Blaine value (2200 cm 2 /g) the compressive strength of concrete at all ages is the higher, the steeper the size distribution curve is. From the plots, an increase about 20% in 28-days …

The simulated product size distributions were found to display a close match with the measured product from an operational mill. Based on the maximum production of floatable particles, the best combination of make-up ball size was determined in relation to feed flow rate, feed size distribution and ball filling.

Thereby, a new cumulative undersize distribution of the prediction model was developed, which was successfully validated by the experimental data against predicted data. Graphical abstract. ... Prediction of Product Size Distributions for a Stirred Ball Mill. Powder Technol. (1995)
