Give it your sieve analysis and it fits the standard Rosin-Rammler distribution, so two numbers describe the whole product: how coarse it is and how wide the spread is. Then it can predict any sieve you did not measure. If the points do not lie on the line, your product is not a single distribution — and that itself tells you something. Press SIEVE ANALYSIS to type yours in.
Clinker reduction, high electricity prices and tighter cement specifications put the grinding circuit under pressure. The fastest gains usually come from finding the real constraint before changing equipment or operation.
Convert sieve results into a particle-size curve, characteristic size and spread that support fineness, quality and mill-setting decisions.
Build a connected grinding audit: save every mill separately, reload previous measurements, compare changes over time and issue an editable report for the plant team.
Connected to the industry conversation around clinker-factor reduction, grinding energy, blended cement and quality control reported in World Cement, CemNet and Global Cement.See process-tool plansSieve size in micrometres, and % retained on that sieve. Leave a row at 0 to skip it. Three rows is the minimum for a fit; more rows make it better. The right-hand column shows what the fitted curve says, so you can see which points disagree.

The width of your distribution is set mostly by the separator. If the spread is wider than you want, the Tromp curve shows you why.
R = 100 × exp(−(d/d′)n), the standard
Rosin-Rammler form, DIN 66145. Take logs twice and it straightens out into
ln(ln(100/R)) = n·ln(d) − n·ln(d′), so a least-squares straight
line through your points gives n as the slope and d′ from the intercept. The chart
plots those exact axes — that is why a good fit looks straight.Γ(1 − 1/n), which blows up as n approaches 1 — and cement sits right
there. Any Blaine printed from an RRSB fit would be a meaningless number. Blaine comes from workbook
formula #4b instead.
