Abstract

Procédé et dispositif de contrôle du comportement de matières granulaires sous l'action d'une pression et de l'abrasion. Les grains d'un échantillon représentatif de la substance granulaire sont soumis à l'action brutale d'une onde de pression gazeuse ayant une énergie cinétique élevée, dans un mortier fermé présentant des caractéristiques particulières. Application à la mesure de la sensibilité à la pression et à l'abrasion de matières granulaires, notamment sous forme de masses granulaires compactes.
