A new model based on dynamic powder flow properties to predict the torque measured in the mechanically stirred fluid-bed rheometer (msFBR) is proposed. A Schulze shear cell was used to measure the powder flow properties. An inverse procedure to evaluate powder flow properties from torque data is proposed and verified with shear cell data.

Abstract
A new model based on dynamic powder flow properties to predict the torque measured in the mechanically stirred fluid-bed rheometer (msFBR) is proposed. A Schulze shear cell was used to measure the powder flow properties. An inverse procedure to evaluate powder flow properties from torque data is proposed and verified with shear cell data.File in questo prodotto:
