What is the Particle Durability Index (PDI) of pellet feed tested by the ST136 Pellet Friability Tester?

The ST136 Pellet Friability Tester (also known as Pellet Durability Tester) is a specialized device designed to measure the Particle Durability Index (PDI) of pellet feed. The PDI is one of the most important indicators reflecting the quality of pellet feed, which measures the relative ability of finished pellet feed to resist breakage during transportation and handling. A higher PDI value indicates stronger breakage resistance of the pellets, better pellet quality, and higher feed utilization rate.

Pellet feed produced by feed factories must have sufficient durability to withstand impact during transportation, reduce fine powder, and meet customers' appearance requirements for pellet feed. The ST136 Pellet Friability Tester fulfills this testing demand by simulating the transportation and handling process of pellet feed.
