Graphite, Anode & Battery Materials Processing calculator

Particle Size Yield Calculator

Calculate the share of graphite or anode powder that meets the particle-size specification after milling, spheroidization, sieving, or air classification. Use it when quality, production, or R&D needs to compare accepted in-spec D10, D50, D90, or classification-cut material against total classified material.

What this calculator does

  • Calculate the share of graphite or anode powder that meets the particle-size specification after milling, spheroidization, sieving, or air classification.
  • Use it when quality, production, or R&D needs to compare accepted in-spec D10, D50, D90, or classification-cut material against total classified material.
  • Measures how much of a graphite or anode powder lot meets the required particle-size distribution.

Formula used

  • Particle-size yield rate = in-spec particle-size mass ÷ total classified or sampled mass × 100
  • Particle-size yield gap to target = particle-size yield rate - target PSD yield

Inputs explained

  • In-spec particle-size mass: Enter powder meeting the customer or internal PSD window, such as D10, D50, D90, oversize, and fines limits.
  • Total classified or sampled mass: Use the total graphite or anode powder mass reviewed for the same run, lot, sieve cut, or classifier pass.
  • Target PSD yield: Use the expected particle-size yield from the control plan, trial target, customer spec, or production standard.

How to use the result

  • Use for classifier settings, sieve changes, milling trials, spheroidization yield checks, and customer-release reviews.
  • This calculator is an estimating and planning tool. Results can change with graphite grade, feedstock lot, natural versus synthetic graphite source, spherical graphite morphology, silicon-carbon blend, hard carbon or soft carbon chemistry, moisture content, ash content, impurity ppm, metal contamination, milling media wear, classifier cut point, D10/D50/D90 distribution, tap density, BET surface area, coating chemistry, coating loading, binder or conductive additive ratio, solvent or solids level, furnace temperature uniformity, residence time, drying endpoint, sampling plan, customer specification, scale-up behavior, maintenance condition, and actual plant operating data. Validate quality release, battery performance, safety, environmental, regulatory, and customer-critical decisions with qualified process, quality, materials, EHS, and engineering experts.

Common questions

  • What information do I need before using the Particle Size Yield? Use in-spec PSD mass, total mass reviewed, and target yield for the same lot and measurement method.
  • What does the result mean? The result shows PSD yield percentage and gap versus target.
  • When is the result only an estimate? This calculator is an estimating and planning tool. Results can change with graphite grade, feedstock lot, natural versus synthetic graphite source, spherical graphite morphology, silicon-carbon blend, hard carbon or soft carbon chemistry, moisture content, ash content, impurity ppm, metal contamination, milling media wear, classifier cut point, D10/D50/D90 distribution, tap density, BET surface area, coating chemistry, coating loading, binder or conductive additive ratio, solvent or solids level, furnace temperature uniformity, residence time, drying endpoint, sampling plan, customer specification, scale-up behavior, maintenance condition, and actual plant operating data. Validate quality release, battery performance, safety, environmental, regulatory, and customer-critical decisions with qualified process, quality, materials, EHS, and engineering experts.
  • What decision can I make from the result? Use it to adjust classifier cut point, milling time, recycle strategy, or whether to release, blend, reclassify, or rework a lot.
