Sand Reclaim Rate at 90% target reclaim rate: a worked example

What does the result look like when target reclaim rate reaches 90%? The full calculation is worked below with real intermediate numbers. Use it when reclaim efficiency affects sand purchases, disposal cost, binder demand, and mold quality.

The inputs for this scenario

  • Reclaimed usable sand: 32,000 lb (unchanged)
  • Total sand processed: 40,000 lb (unchanged)
  • Target reclaim rate: 90 % (raised for this scenario; the documented default is 78)

Working through the calculation

  • Applying the documented formula (Sand Reclaim Rate rate = reclaimed usable sand ÷ total sand processed × 100) to the inputs above produces each figure below.
  • At this operating point the engine returns 80 % for sand reclaim rate rate, the number this scenario is built around.
  • At this operating point the engine returns 10 points for sand reclaim rate gap to target.
  • At this operating point the engine returns 32,000 count for reclaimed usable sand.
  • At this operating point the engine returns 40,000 count for total sand processed.

How this compares with the baseline

  • Against the tool's baseline example, where target reclaim rate sits at 78% and the headline result is 80 %, this scenario lands almost exactly on the baseline at 80 %.
  • A figure at this level is achievable when target reclaim rate is genuinely sustained, not just peaked for a shift. It measures recovery percent only; it does not judge reclaimed-sand quality such as LOI, fines content, or residual binder, which can fail even at a high reclaim rate.

Results at a glance

  • Sand Reclaim Rate rate: 80 % (headline result)
  • Sand Reclaim Rate gap to target: 10 points
  • Reclaimed usable sand: 32,000 count
  • Total sand processed: 40,000 count
