Mixing, Blending & Industrial Batch Processing calculator

Batch Cycle OEE Calculator

Measure OEE for repeated batches with one recipe, batch size and ideal cycle. Enter planned and running time, completed and first-pass-good counts, and your target.

What this calculator does

  • Calculate batch OEE and its three loss factors from time records and first-pass batch counts.

Formula used

  • Availability % = operating hours ÷ planned hours × 100
  • Performance % = ideal batch minutes × completed batches ÷ (operating hours × 60) × 100
  • Quality % = first-pass-good batches ÷ completed batches × 100
  • Fully productive hours = ideal batch minutes × first-pass-good batches ÷ 60
  • OEE % = fully productive hours ÷ planned hours × 100; target margin = OEE % − target %

Inputs explained

  • Mixer Operating Time: Recorded running hours after production stops are removed.
  • Planned Production Time: Scheduled production hours, excluding periods with no production intention.
  • Ideal Batch Cycle: Demonstrated fastest achievable cycle for this recipe and batch size.
  • Completed Batch Count: Total equal-size batches completed during the recorded period.
  • First-Pass-Good Batch Count: Completed batches accepted without any rework.
  • OEE Target: Your improvement target for this equipment and production boundary.

How to use the result

  • Best suited to identical batch OEE Review, First-Pass batch loss analysis.
  • Mixed products or unequal batch sizes need an appropriately weighted model. No completed batches or zero runtime cannot support all three factors. Performance above 100% requires correcting the ideal cycle or reporting boundary.

Common questions

  • Can I count batches with different masses? Not in this model. Equal counts are comparable only when recipe, batch size and ideal cycle are the same.
  • Does reworked material count as good? No. First-pass quality excludes batches needing rework, even when they are eventually accepted.
  • Why is performance above 100% blocked? It contradicts the entered ideal cycle. Check whether that cycle is too slow, the counts include another period, or operating time is understated.
  • Is 85% automatically the target? No. Enter a target appropriate to your equipment and business. This calculator applies no universal OEE benchmark.
