Bulk Solids Shrinkage at 65% conveying and storage availability: a worked example

Suppose conveying and storage availability falls to 65%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Estimate bulk solids shrinkage for bulk solids shrinkage for bulk solids, mining, aggregates, and material processing using plant-floor material, production, quality, capacity, or cost inputs.

The inputs for this scenario

  • Net product tonnage per handling cycle: 18 tons / cycle (held at the documented default)
  • Available handling or transfer cycles in the period: 240 cycles (held at the documented default)
  • Conveying and storage availability: 65 % (the input this scenario stresses; the baseline uses 90)
  • First-pass retained-material yield: 96 % (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Gross bulk solids shrinkage = bulk solids shrinkage output per cycle × available bulk solids shrinkage cycles.
  • Bulk Solids Shrinkage works out to 2,696 tons at these inputs, and this is the headline figure for the scenario.
  • Gross bulk solids shrinkage works out to 4,320 tons at these inputs.
  • Bulk Solids Shrinkage uptime loss works out to 1,512 tons at these inputs.
  • Bulk Solids Shrinkage yield loss works out to 112 tons at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where conveying and storage availability sits at 90% and the headline result is 3,732 tons, this scenario comes in 27.78% below the baseline at 2,696 tons.
  • It computes the net tonnage retained after handling, by applying conveying availability and first-pass retained yield to gross cycle output. 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.
