Auger Rate at 99% target auger rate attainment: a worked example
What does the result look like when target auger rate attainment reaches 99%? The full calculation is worked below with real intermediate numbers. Use it when a screw conveyor, auger, or feeder is suspected of limiting grain, meal, pellet, flour, or ingredient flow to a bin, mixer, mill, or bagging line.
The inputs for this scenario
- Actual auger conveyed weight: 44 tons (unchanged)
- Planned auger conveyed weight: 50 tons (unchanged)
- Target auger rate attainment: 99 % (raised for this scenario; the documented default is 92)
Working through the calculation
- Applying the documented formula (Auger rate attainment = actual auger conveyed weight ÷ planned auger conveyed weight × 100) to the inputs above produces each figure below.
- At this operating point the engine returns 88 % for auger rate attainment, the number this scenario is built around.
- At this operating point the engine returns 11 points for auger rate gap to target.
- At this operating point the engine returns 44 count for actual auger conveyed weight.
- At this operating point the engine returns 50 count for planned auger conveyed weight.
How this compares with the baseline
- Against the tool's baseline example, where target auger rate attainment sits at 92% and the headline result is 88 %, this scenario lands almost exactly on the baseline at 88 %.
- A figure at this level is achievable when target auger rate attainment is genuinely sustained, not just peaked for a shift. It measures attainment against your own plan, so an optimistic or stale plan figure will flatter or punish the auger unfairly — the number is only as honest as the planned tonnage you feed it.
