Abstract
Particle shape classification technique of P/M powders is introduced for high-grade powder preparation, which leads to the stabilization of P/M processing and the high quality of P/M products. The vibrating inclined plate method was used for the shape classification. In the particle shape separator, powder particles rolled down on an inclined plate vibrated by an electromagnetic vibrator. The morphological characteristics of both powders before and after testing were examined with the particle size-shape dispersion diagrams in order to investigate the influences of the operating conditions on the shape classification. Moreover, a simulation of this shape classification was attempted according to the kinetics of collision between ellipsoidalparticles and an inclined plate.
