Metal Recycling, Scrap Processing & Salvage worked example

Scrap Freight Burden at 12% setup, tarping, and weigh-in delay allowance: a worked example

What does the result look like when setup, tarping, and weigh-in delay allowance reaches 12%? The full calculation is worked below with real intermediate numbers. Use it when scrap freight burden in metal recycling, scrap processing and salvage is being added to next week's schedule and you need an honest hours estimate.

The inputs for this scenario

  • Tonnage of scrap to haul this shift: 120 units (unchanged)
  • Loading throughput per loader-minute: 12 units / min (unchanged)
  • Setup, tarping, and weigh-in delay allowance: 12 % (raised for this scenario; the documented default is 10)

Working through the calculation

  • Applying the documented formula (Base scrap freight burden time = scrap freight burden workload รท scrap freight burden completion rate) to the inputs above produces each figure below.
  • At this operating point the engine returns 11.2 hr for required scrap freight burden time, the number this scenario is built around.
  • At this operating point the engine returns 10 hr for base scrap freight burden time.
  • At this operating point the engine returns 12 % for scrap freight burden allowance applied.
  • At this operating point the engine returns 12 pieces / min for scrap freight burden completion rate.

How this compares with the baseline

  • Against the tool's baseline example, where setup, tarping, and weigh-in delay allowance sits at 10% and the headline result is 11 hr, this scenario comes in 1.82% above the baseline at 11.2 hr.
  • A figure at this level is achievable when setup, tarping, and weigh-in delay allowance is genuinely sustained, not just peaked for a shift. It assumes a single steady loading rate; in practice grade segregation, magnet downtime, and scale congestion can swing real throughput far more than the flat allowance captures.

Results at a glance

  • Required scrap freight burden time: 11.2 hr (headline result)
  • Base scrap freight burden time: 10 hr
  • Scrap freight burden allowance applied: 12 %
  • Scrap freight burden completion rate: 12 pieces / min
