Мениджър на размера на въгленовите частици и дела на фините частици

Проверявайте дали един въгленов лот пасва на даден клас за продажба според пресяването и дела на фините частици.

Работи изцяло в браузъра и помага да сравните профили, да преглеждате резултати и да записвате локални профили.

How to use

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

Примери

A lot suited for BBQ

Input

50 mm: 4%, 30 mm: 38%, 20 mm: 36%, 10 mm: 17%, pan: 5%, fines ratio: 5%

Output

Ship ok / Recommended use: BBQ / Low fines and a high main fraction

A lot with conditional commercial fit

Input

50 mm: 8%, 30 mm: 28%, 20 mm: 30%, 10 mm: 20%, pan: 14%

Output

Review / Recommended use: Commercial / Fines ratio is slightly high

A lot to rework before industrial use

Input

Fines ratio: 18% / no sieve table entered

Output

Hold / Recommended use: Industrial candidate / Reference judgment because no sieve table was entered

Речник

Particle size distribution

The distribution of retained and passing percentages by sieve.

Fines ratio

The share of particles treated as fines.

Cumulative passing

The share 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 × 100
  • Cumulative passing % = 100 - cumulative retained %
  • Fines ratio = fines mass / total mass × 100
  • Span = (D90 - D10) / D50

ЧЗВ

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 logic are shared; only the display text is translated.

Бележки

  • 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.
