Metals, Steel, Aluminum & Coil Processing worked example
Scrap Recovery Rate at 99% sortation and yield efficiency: a worked example in metals, steel, aluminum & coil processing
This scenario runs the scrap recovery rate calculation on the strong side: 99% sortation and yield efficiency, with every other input held at its documented default. Use it when an operations manager tracks how fast scrap and trim are baled, processed, or shipped per hour.
The inputs for this scenario
- Scrap metal recovered: 12,000 lb (unchanged)
- Recovery run time: 8 hr (unchanged)
- Sortation and yield efficiency: 99 % (raised for this scenario; the documented default is 90)
Working through the calculation
- Applying the documented formula (Scrap recovery rate = scrap recovered รท run time) to the inputs above produces each figure below.
- At this operating point the engine returns 1,485 lb/hr for effective recovery rate, the number this scenario is built around.
- At this operating point the engine returns 1,500 lb/hr for raw throughput.
- At this operating point the engine returns 99 % for recovery efficiency.
- At this operating point the engine returns 8 hr for run time.
How this compares with the baseline
- Against the tool's baseline example, where sortation and yield efficiency sits at 90% and the headline result is 1,350 lb/hr, this scenario comes in 10% above the baseline at 1,485 lb/hr.
- Use it at shift end to grade performance, when comparing two pieces of recovery equipment, or when quoting a scrap-processing contract. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.
