How to use
- Enter lot information, sample mass, spec name, and the sieve stack used.
- Enter the retained amount for each sieve and the fines ratio if you have it.
- Choose a use profile and check shipping readiness and the recommended use.
- Save as CSV or JSON if needed, and open it in another language.

Glossary
Particle size distribution
The distribution of retained and passing percentages by sieve.
Fines ratio
The paylaşım of particles treated as fines.
Cumulative passing
The paylaşım that passed through the sieve.
D50
A median-size proxy for the particle distribution.
Span
A spread index calculated as (D90 - D10) / D50.
Formulas
Retained % = retained mass / total mass × 100Cumulative passing % = 100 - cumulative retained %Fines ratio = fines mass / total mass × 100Span = (D90 - D10) / D50
SSS
Can fines ratio be calculated from the sieve table?
Yes. It can be calculated from the pan row or from the total below the configured cutoff.
Are the BBQ, commercial, and industrial thresholds fixed?
No. The defaults are reference bands and can be tuned for each market.
Can I use mesh labels only?
Mesh can be used as a label, but the calculation uses opening size values.
Can I see the same result in other languages?
Yes. The state keys and decision kayıtic are paylaşımd; only the display text is translated.
Notlar
- These thresholds are starting values. Tune them for each market.
- Check the opening size, not just the mesh label.
- Compare only when the mass basis is aligned: as received or dry.
- This tool supports shipping decisions but does not replace certification or contract specs.
