Graphite, Anode & Battery Materials Processing worked example

Particle Size Yield at 61% target psd yield: a worked example in graphite, anode & battery materials processing

Suppose target psd yield falls to 61%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Calculate the share of graphite or anode powder that meets the particle-size specification after milling, spheroidization, sieving, or air classification.

The inputs for this scenario

  • In-spec particle-size mass: 820 kg (held at the documented default)
  • Total classified or sampled mass: 1,000 kg (held at the documented default)
  • Target PSD yield: 61 % (the input this scenario stresses; the baseline uses 85)

Working through the calculation

  • The calculation starts from the formula this tool documents: Particle-size yield rate = in-spec particle-size mass ÷ total classified or sampled mass × 100.
  • Particle-size yield rate works out to 82 % at these inputs, and this is the headline figure for the scenario.
  • Particle-size yield gap to target works out to -21 points at these inputs.
  • In-spec particle-size mass works out to 820 count at these inputs.
  • Total classified or sampled mass works out to 1,000 count at these inputs.

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 %.
  • It computes the percentage of total classified or sampled mass that meets PSD spec, then reports how far that sits above or below your target yield. When the numbers land here, the stressed input is the lever to work; the walkthrough above shows exactly how much each output recovers as it climbs back toward the baseline.
