Bulk Solids, Mining, Aggregates & Material Processing worked example

Bulk Bag Fill Rate at 99% target bulk bag fill rate: a worked example

This scenario runs the bulk bag fill rate calculation on the strong side: 99% target bulk bag fill rate, with every other input held at its documented default. a plant team is reviewing bulk bag fill rate for bulk solids, mining, aggregates, and material processing and needs a clear bulk bag fill rate for production, quality, capacity, maintenance, purchasing, or costing decisions

The inputs for this scenario

  • Bulk Bag Fill Rate accepted or affected material: 850 tons (unchanged)
  • Total silo, hopper, bin, or bulk bag material in same period: 1,000 tons (unchanged)
  • Target bulk bag fill rate: 99 % (raised for this scenario; the documented default is 95)

Working through the calculation

  • Applying the documented formula (Bulk Bag Fill Rate = bulk bag fill rate accepted or affected material ÷ total silo, hopper, bin, or bulk bag material in same period × 100) to the inputs above produces each figure below.
  • At this operating point the engine returns 85 % for bulk bag fill rate, the number this scenario is built around.
  • At this operating point the engine returns 14 points for bulk bag fill rate gap to target.
  • At this operating point the engine returns 850 count for bulk bag fill rate accepted or affected material.
  • At this operating point the engine returns 1,000 count for total silo, hopper, bin, or bulk bag material in same period.

How this compares with the baseline

  • Against the tool's baseline example, where target bulk bag fill rate sits at 95% and the headline result is 85 %, this scenario lands almost exactly on the baseline at 85 %.
  • Use it at the end of each shift or batch run to verify that metered material is converting into saleable filled bags and to flag densification or spillage losses. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.

Results at a glance

  • Bulk Bag Fill Rate: 85 % (headline result)
  • Bulk Bag Fill Rate gap to target: 14 points
  • Bulk Bag Fill Rate accepted or affected material: 850 count
  • Total silo, hopper, bin, or bulk bag material in same period: 1,000 count
