Pellet Durability Loss at 68% target maximum durability loss rate: a worked example

Here is what the math looks like when conditions slip. We hold every other input steady and drop target maximum durability loss rate to 68%, then walk the calculation through step by step. Estimate pellet durability loss for pet food and animal nutrition manufacturing using production-ready inputs so teams can track KPI performance and decide whether corrective action is needed.

The inputs for this scenario

  • Fines and broken pellets after tumbling: 8 count (held at the documented default)
  • Total pellets in durability test sample: 250 count (held at the documented default)
  • Target maximum durability loss rate: 68 % (the input this scenario stresses; the baseline uses 95)

Working through the calculation

  • The calculation starts from the formula this tool documents: Pellet durability loss rate = pellet durability loss count ÷ total pellet durability loss population × 100.
  • Pellet durability loss rate works out to 3.2 % at these inputs, and this is the headline figure for the scenario.
  • Pellet durability loss gap to target works out to 64.8 points at these inputs.
  • Pellet durability loss count works out to 8 count at these inputs.
  • Total pellet durability loss population works out to 250 count at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where target maximum durability loss rate sits at 95% and the headline result is 3.2 %, this scenario lands almost exactly on the baseline at 3.2 %.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to target maximum durability loss rate, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. The result is only as valid as the test method and sample handling; Holmen and tumbling-box testers give different absolute numbers, so never benchmark a Holmen loss rate against a tumbling-box target.

Results at a glance

  • Pellet durability loss rate: 3.2 % (headline result)
  • Pellet durability loss gap to target: 64.8 points
  • Pellet durability loss count: 8 count
  • Total pellet durability loss population: 250 count
