Weighing, Dosing & Loss-in-Weight Feeding worked example

Bulk Density Adjustment with volumetric feed rate at reference density of 250 units: a worked example

This scenario runs the bulk density adjustment calculation on the strong side: volumetric feed rate at reference density of 250 units, with every other input held at its documented default. Use it when bulk density adjustment in weighing, dosing and loss-in-weight feeding needs a few factors combined into one defensible number for weighing, dosing and loss-in-weight feeding.

The inputs for this scenario

  • Volumetric feed rate at reference density: 250 units (raised for this scenario; the documented default is 100)
  • Reference bulk density of the material: 4 units (unchanged)
  • Density ratio correction factor: 0.01 x (unchanged)
  • Feeder efficiency / process multiplier: 1 x (unchanged)

Working through the calculation

  • Applying the documented formula (Bulk Density Adjustment = first factor × second factor × conversion factor × process multiplier) to the inputs above produces each figure below.
  • At this operating point the engine returns 5 units for result, the number this scenario is built around.
  • At this operating point the engine returns 5 value for base product.
  • At this operating point the engine returns 1 x for multiplier.
  • At this operating point the engine returns 1,000 value for factor a x b.

How this compares with the baseline

  • Against the tool's baseline example, where volumetric feed rate at reference density sits at 100 units and the headline result is 2 units, this scenario comes in 150% above the baseline at 5 units.
  • Use it whenever a new material lot, moisture change, or aeration state shifts bulk density away from the density at which the feeder was last calibrated. 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

  • Result: 5 units (headline result)
  • Base product: 5 value
  • Multiplier: 1 x
  • Factor A x B: 1,000 value
