The KSU Tumbler has a few short-comings that has led to modification or development of completely new testers. The tumbler was developed using pellets that were primarily corn/soya in make up. When used to evaluate dairy pellets of high durability (PDI>96) the standard test is not abrasive enough to discriminate levels of quality.
iron ore pellet tumbler index jolitchconstruction.co.za. Iron ore pellet is a type of agglomerated iron ore fines which has better tumbler index when compared with that of parent iron ore and can be used as a substitute of lump ore for the production of direct reduced iron (DRI) and in blast furnaces for the production of hot metal.

Pellet and crumbles durability is defined as: Durability = Weight of pellets or crumbles after tumbling (___ g) × 100 Weight of pellets or crumbles before tumbling (500g) This value is known as the pellet durability index (PDI) and is typically reported as a percentage (e.g. 95 percent PDI). Normally, the pellets should be tested
minutes, after which the pellets are removed and screened. The pellet durability index (PDI) is defined as the percentage of pellets surviving the test and retained on the screen (Pfost, 1976). The KSU Tumbler often shows good correlation to the actual quality of pellets delivered to the animal.
