Can Particle Size Predict Powder Flow Behavior?
Jun 25, 2012For powder mixtures that have particle sizes of variable diameter, the general observation is that the large particles go along for the ride. The smaller size particles determine the flow behavior. So what is the correct method to measure flow behavior? Can a particle size analyzer get the job done all by itself? Not necessarily.
