METHOD AND DEVICE FOR CHARACTERIZING GRANULE STRENGTH

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 meas...

Summary: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 obtained yield a highly reproducible means for characterizing granule attrition and fragmentation. La présente invention concerne un procédé et un dispositif servant à mesurer la résistance aux chocs de granules, ce procédé consistant à faire vibrer un petit récipient de granules à une amplitude bien régulée, afin d'infliger des dommages reproductibles aux granules, puis à mesurer ces dommages en fonction de la durée et de l'amplitude des vibrations. Les mesures obtenues constituent des moyens très reproductibles de caractérisation de l'attrition et de la fragmentation.
