The Scrap Recovery Throughput Estimator measures how quickly a recovery line converts incoming scrap into usable recovered material. It reports recovered mass per operating hour, making it useful for recycling cells, reclaim systems, regrind operations, and internal material-recovery processes where output rate matters as much as yield.
Use the estimate to compare shifts, check whether a recovery step can keep up with upstream scrap generation, or translate a batch result into an hourly and shift-level capacity. Because the calculation is based on actual recovered output and actual operating time, planned breaks or idle periods should only be included when they are part of the time basis you want to evaluate.
1. Enter recovered output
Use the mass of usable material actually recovered during the measured run, not the incoming scrap mass.
2. Enter operating time
Use the hours during which the recovery process was running on the measured output.
3. Set a shift length
Choose the number of operating hours you want to use for the shift-level projection.
4. Review the rates
Compare the hourly rate with the per-minute and projected shift outputs to evaluate capacity.
Recovered material is measured in kilograms, operating time in hours, and throughput in kilograms per hour. The projection assumes the measured average rate continues through the reference shift without a material change in downtime, feed quality, or operating conditions.
The main result is the average usable recovery output produced during each operating hour.
A throughput estimate describes rate, not recovery efficiency. Compare it with yield or loss metrics when the quality of the recovered fraction also matters.
Given
Calculation
Throughput = 1,250 ÷ 6.5 = 192.31 kg/hr. Projected shift output = 192.31 × 8 = 1,538.46 kg.
Result
Estimated throughput = 192.31 kg/hr.
At the measured pace, an eight-hour operating shift would recover about 1.54 metric tons if the average rate remains stable.
Use recovered usable material for the numerator. Incoming scrap belongs in a recovery-yield calculation, while this tool focuses on output rate.
Include a stop only if you want that time to reduce the measured throughput. For a pure run-rate measure, use only active operating time.
Yield measures the share of input recovered, while throughput measures how fast recovered output is produced. A slower run can preserve yield but still reduce hourly capacity.
The arithmetic works with any consistent mass unit, but the page labels results in kilograms. Convert pounds to kilograms before entering values if you want the displayed units to remain correct.
Treat it as a pace-based capacity estimate, not a guaranteed production quantity. Longer stops, feed changes, maintenance, or operator constraints can make actual shift output differ.
