Mixing, Blending & Industrial Batch Processing worked example

Throughput Per Shift at 61% line utilization: a worked example in mixing, blending & industrial batch processing

Here is what the math looks like when conditions slip. We hold every other input steady and drop line utilization to 61%, then walk the calculation through step by step. Estimate effective batch plant throughput from completed batch output, mixer runtime, and realistic line utilization.

The inputs for this scenario

  • Completed batch output: 9,000 kg (held at the documented default)
  • Mixer runtime in shift: 8 hr (held at the documented default)
  • Line utilization: 61 % (the input this scenario stresses; the baseline uses 85)

Working through the calculation

  • The calculation starts from the formula this tool documents: Raw throughput = completed batch output รท mixer runtime in shift.
  • Effective throughput works out to 686 kg / hr at these inputs, and this is the headline figure for the scenario.
  • Raw throughput works out to 1,125 kg / hr at these inputs.
  • Efficiency works out to 61 % at these inputs.
  • Runtime works out to 8 hr at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where line utilization sits at 85% and the headline result is 956 kg / hr, this scenario comes in 28.24% below the baseline at 686 kg / hr.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to line utilization, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. It treats utilization as a single average percentage, so it won't surface intermittent bottlenecks, micro-stoppages, or variation between batch types within the shift.

Results at a glance

  • Effective throughput: 686 kg / hr (headline result)
  • Raw throughput: 1,125 kg / hr
  • Efficiency: 61 %
  • Runtime: 8 hr
