Scrap Recovery Throughput Calculator
Estimate how much recovered material a scrap-processing operation produces per hour and per shift. Enter the material loaded, recovery rate, operating time, and shift length to separate gross feed from usable recovered output and see how recovery losses affect practical capacity.
Calculator
Output and operating timeFormula
Usable output = feed × recovery rate; hourly throughput = usable output ÷ active hours.
What the result means
The main result describes the measured rate or loss for the entered operating period. Read it together with the supporting figures to avoid confusing speed, capacity, quality, and material efficiency.
This is an operational estimate. Validate input definitions against your plant records before using the result for staffing, costing, or capital decisions.
Example calculation
With 800 kg loaded, an 85% recovery rate, and 8 active hours, usable output is 680 kg and throughput is 85 kg/hour.
Tips for better results
- Use data from comparable jobs and operating conditions.
- Separate planned stops from unexpected delays.
- Keep good output and total output definitions consistent.
- Investigate the largest loss component first.
- Repeat the calculation over several periods before treating a change as a trend.
Frequently asked questions
Can I use partial production units in this calculator?
Yes. Decimal inputs are accepted where the measured quantity or time is not a whole number.
How should planned downtime be entered for scrap recovery?
Enter only the time excluded by the field label. Keep the measurement period consistent across all inputs.
Why can the result change when the same total output is used?
Time, usable output, demand, or quality inputs change the denominator or effective output, so the resulting rate changes.
Does this calculator set an industry target for scrap recovery?
No. Appropriate targets depend on equipment, material, product mix, and operating conditions.
Can I compare two scrap recovery periods?
Yes. Run each period separately with the same units and definitions, then compare the displayed primary and secondary results.
