The fluidization of a cohesive silica powder has been tested with the help of mechanical vibration. The experiments showed how the effectiveness of vibrations changed with the vibrational acceleration and frequency. The aggregative behavior of powders has been highlighted and a model procedure is proposed to predict the aggregate size starting from the measurement of powder flow properties with conventional shear testers.

Abstract

The fluidization of a cohesive silica powder has been tested with the help of mechanical vibration. The experiments showed how the effectiveness of vibrations changed with the vibrational acceleration and frequency. The aggregative behavior of powders has been highlighted and a model procedure is proposed to predict the aggregate size starting from the measurement of powder flow properties with conventional shear testers.
