Once a sample is manually weighed and loaded into the tester, the Fine Material Amount (F) cycles lasts 30 seconds and Mechanical Durability (DU) test cycle lasts 60 seconds. Fines and dust are removed during the DU test cycle, resulting in no further sieving being required.

The Holmen Pellet Durability Test is a form of testing that is recognised and used worldwide. Four models are available in the range, providing a solution for any mill or facility.
