Mixing, Blending & Industrial Batch Processing worked example

Batch Size at 99% effective mixer uptime: a worked example in mixing, blending & industrial batch processing

This scenario runs the batch size calculation on the strong side: 99% effective mixer uptime, with every other input held at its documented default. Use it when sales is pushing more volume into the schedule and you need to show how many good batches the mixing line can actually deliver per shift.

The inputs for this scenario

  • Output per batch: 4 units / batch (unchanged)
  • Batches scheduled per shift: 480 batches (unchanged)
  • Effective mixer uptime: 99 % (raised for this scenario; the documented default is 90)
  • First-pass batch yield: 97 % (unchanged)

Working through the calculation

  • Applying the documented formula (Gross batch output = output per batch × batches scheduled per shift) to the inputs above produces each figure below.
  • At this operating point the engine returns 1,844 batches for good output capacity, the number this scenario is built around.
  • At this operating point the engine returns 1,920 batches for gross capacity.
  • At this operating point the engine returns 19.2 batches for uptime loss.
  • At this operating point the engine returns 57.02 batches for yield loss.

How this compares with the baseline

  • Against the tool's baseline example, where effective mixer uptime sits at 90% and the headline result is 1,676 batches, this scenario comes in 10% above the baseline at 1,844 batches.
  • Use it when sizing a shift schedule, committing volume to a customer, or comparing a line's nameplate capacity against what it realistically ships. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.

Results at a glance

  • Good output capacity: 1,844 batches (headline result)
  • Gross capacity: 1,920 batches
  • Uptime loss: 19.2 batches
  • Yield loss: 57.02 batches
