Batch Weigh Accuracy at 99% target batch weigh accuracy: a worked example

Push target batch weigh accuracy up to 99% and the picture changes. This example computes every intermediate figure at that operating point. a plant team is reviewing batch weigh accuracy for bulk solids, mining, aggregates, and material processing and needs a clear batch weigh accuracy for production, quality, capacity, maintenance, purchasing, or costing decisions

The inputs for this scenario

  • Weight correctly batched within tolerance: 850 tons (unchanged)
  • Total material weighed in the same period: 1,000 tons (unchanged)
  • Target batch weigh accuracy: 99 % (raised for this scenario; the documented default is 95)

Working through the calculation

  • Applying the documented formula (Batch Weigh Accuracy = batch weigh accuracy 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 batch weigh accuracy, the number this scenario is built around.
  • At this operating point the engine returns 14 points for batch weigh accuracy gap to target.
  • At this operating point the engine returns 850 count for batch weigh accuracy 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 batch weigh accuracy sits at 95% and the headline result is 85 %, this scenario lands almost exactly on the baseline at 85 %.
  • It computes the percentage of total weighed tonnage that was batched within tolerance, plus the point gap to your accuracy target. The value of this scenario is the size of the gap it exposes: that gap, priced out over a year, is the budget you can justify spending to close it.

Results at a glance

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