  • Repeated impact apparatus and method for characterizing granule strength
    Patent number: 6457345
    Abstract: The present invention provides methods and devices for measuring granule impact strength and granule attrition rates 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 and attrition rates are measured in terms of dust generate per number of collisions versus mass of the granules. The measurements obtained yield a highly reproducible means for characterizing granule attrition, attrition rates, and fragmentation.
