Graphite, Anode & Battery Materials Processing worked example

Particle Size Yield at 98% target psd yield: a worked example in graphite, anode & battery materials processing

What does the result look like when target psd yield reaches 98%? The full calculation is worked below with real intermediate numbers. 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.

The inputs for this scenario

  • In-spec particle-size mass: 820 kg (unchanged)
  • Total classified or sampled mass: 1,000 kg (unchanged)
  • Target PSD yield: 98 % (raised for this scenario; the documented default is 85)

Working through the calculation

  • Applying the documented formula (Particle-size yield rate = in-spec particle-size mass ÷ total classified or sampled mass × 100) to the inputs above produces each figure below.
  • At this operating point the engine returns 82 % for particle-size yield rate, the number this scenario is built around.
  • At this operating point the engine returns 16 points for particle-size yield gap to target.
  • At this operating point the engine returns 820 count for in-spec particle-size mass.
  • At this operating point the engine returns 1,000 count for total classified or sampled mass.

How this compares with the baseline

  • Against the tool's baseline example, where target psd yield sits at 85% and the headline result is 82 %, this scenario lands almost exactly on the baseline at 82 %.
  • A figure at this level is achievable when target psd yield is genuinely sustained, not just peaked for a shift. It is a mass-fraction metric and says nothing about which tail (oversize vs fines) is failing, so a passing yield can still hide a shifting D50 that a full PSD curve would catch.
