PDI

[Md. Abdul Bari]

Finer ingredient particle sizes generally improve the Pellet Durability Index (PDI) and pellet quality by increasing surface area for better starch gelatinization and adhesion, but overly fine grinding reduces pellet durability and can negatively affect production rates and equipment efficiency. The optimal particle size balances the benefits of finer particles with the risks of excessive grinding, creating stronger, more durable pellets through better heat and moisture penetration and particle binding, according to the National Institutes of Health (NIH) sources.
