Gas fluidization with the help of mechanical vibration of a cohesive silica powder and a potato starch powder has been tested. 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
Gas fluidization with the help of mechanical vibration of a cohesive silica powder and a potato starch powder has been tested. 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.File in questo prodotto:
