Glossary
Particle size distribution
The distribution of retained and passing percentages by sieve.
Fines ratio
İnce tanecik olarak değerlendirilen parçacıkların oranı.
Cumulative passing
Elekten geçen oran.
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?
Evet. Durum anahtarları ve karar mantığı paylaşılır; yalnızca ekran metni çevrilir.
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.
