Mixing Batch Time at 23% charging, sampling, and adjustment allowance: a worked example

This scenario runs the mixing batch time calculation on the strong side: 23% charging, sampling, and adjustment allowance, with every other input held at its documented default. scheduling mixers, kettles, reactors, or blend tanks for batch production

The inputs for this scenario

  • Batch workload to mix: 4,800 lb (unchanged)
  • Mixer throughput rate: 80 lb / min (unchanged)
  • Charging, sampling, and adjustment allowance: 23 % (raised for this scenario; the documented default is 20)

Working through the calculation

  • Applying the documented formula (Base mixing batch time = batch workload to mix รท mixer processing rate) to the inputs above produces each figure below.
  • At this operating point the engine returns 73.8 hr for estimated mixing batch time, the number this scenario is built around.
  • At this operating point the engine returns 60 hr for base mixing batch time.
  • At this operating point the engine returns 23 % for charging, sampling, and adjustment allowance.
  • At this operating point the engine returns 80 pieces / min for mixer processing rate.

How this compares with the baseline

  • Against the tool's baseline example, where charging, sampling, and adjustment allowance sits at 20% and the headline result is 72 hr, this scenario comes in 2.5% above the baseline at 73.8 hr.
  • Use it when scheduling a disperser or planetary mixer, sizing daily mixing capacity, or quoting batch lead time on coatings, inks, and specialty chemical formulas. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.
