Aggregate Yield at 99% target aggregate yield: a worked example

What does the result look like when target aggregate yield reaches 99%? The full calculation is worked below with real intermediate numbers. a plant team is reviewing aggregate yield for bulk solids, mining, aggregates, and material processing and needs a clear aggregate yield for production, quality, capacity, maintenance, purchasing, or costing decisions

The inputs for this scenario

  • On-spec product recovered: 850 tons (unchanged)
  • Total feed processed in the same period: 1,000 tons (unchanged)
  • Target aggregate yield: 99 % (raised for this scenario; the documented default is 95)

Working through the calculation

  • Applying the documented formula (Aggregate Yield = aggregate yield accepted or affected material ÷ total ore, aggregate, powder, sand, gravel, fines, or bulk solid in same period × 100) to the inputs above produces each figure below.
  • At this operating point the engine returns 85 % for aggregate yield, the number this scenario is built around.
  • At this operating point the engine returns 14 points for aggregate yield gap to target.
  • At this operating point the engine returns 850 count for aggregate yield accepted or affected material.
  • At this operating point the engine returns 1,000 count for total ore, aggregate, powder, sand, gravel, fines, or bulk solid in same period.

How this compares with the baseline

  • Against the tool's baseline example, where target aggregate yield sits at 95% and the headline result is 85 %, this scenario lands almost exactly on the baseline at 85 %.
  • A figure at this level is achievable when target aggregate yield is genuinely sustained, not just peaked for a shift. It is a mass-balance ratio, not a value-weighted one: a high-yield run that produces the wrong size mix or low-value fines can still miss revenue targets the percentage looks fine.

Results at a glance

  • Aggregate Yield: 85 % (headline result)
  • Aggregate Yield gap to target: 14 points
  • Aggregate Yield accepted or affected material: 850 count
  • Total ore, aggregate, powder, sand, gravel, fines, or bulk solid in same period: 1,000 count
