Compressive resistance test simulates the compressive
stress due to weight of the top pellets on the lower pellets
during storage in bins or silos, crushing of pellets in a screw
conveyor, and crushing (i.e., chewing) of feed pellets between
animal teeth. The Kahl tester, Stokes tester, Schleuniger
tester, tablet hardness tester, universal testing machine (Instron),
and Kramer shear strength tester have been used to
measure the compressive strength of the densified products
