ABSTRACT:
The present invention provides a method and device for measuring granule impact strength by vibrating a small container of granules at a well-controlled amplitude in order to inflict reproducible damage to the granules. Damage to the granules is measured as a function of time and amplitude. The measurements characterize granule attrition and fragmentation.
