A preliminary model for mechanofusion powder processing

Abstract

Mechanofusion (MF) is a unique high energy powder processing technique, in which powder characteristics can be significantly modified. The effects of MF on powdered materials depend on MF operating conditions and the starting powders. This paper proposes a preliminary MF modeling concept to develop quantitative relationships among MF variables and their effects. In the modeling, an inner piece "action zone" is defined. It is believed that most MF effects are generated when the particles pass through the action zone. From the model, the pressure imposed on the powders by MF can be described via the geometry of the device, operation speed and material properties. In addition, some basic particle kinematics variables can be estimated. The results derived from the modeling are compared to reported experimental results.
