Bin Capacity at 66% bin loading uptime: a worked example

Suppose bin loading uptime falls to 66%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Estimate usable bin, hopper, or silo capacity for grain, flour, feed, pellets, or dry ingredients using fill per loading cycle, loading cycles, uptime, and usable yield.

The inputs for this scenario

  • Tons loaded per cycle: 22 tons / cycle (held at the documented default)
  • Available loading cycles: 12 cycles (held at the documented default)
  • Bin loading uptime: 66 % (the input this scenario stresses; the baseline uses 92)
  • Usable storage yield: 88 % (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Gross bin capacity = tons loaded per cycle × available loading cycles.
  • Usable bin capacity works out to 153 tons at these inputs, and this is the headline figure for the scenario.
  • Gross loaded bin capacity works out to 264 tons at these inputs.
  • Bin loading downtime loss works out to 89.76 tons at these inputs.
  • Unusable storage allowance works out to 20.91 tons at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where bin loading uptime sits at 92% and the headline result is 214 tons, this scenario comes in 28.26% below the baseline at 153 tons.
  • It computes usable bin capacity in tons by multiplying tons-per-cycle by available cycles for a gross figure, then derating by loading uptime and usable storage yield. 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.

Results at a glance

  • Usable bin capacity: 153 tons (headline result)
  • Gross loaded bin capacity: 264 tons
  • Bin loading downtime loss: 89.76 tons
  • Unusable storage allowance: 20.91 tons
