  • Computer Simulation of Particle Size Classification in Air

    performance of air separators uses the concept of efficiency curves, known as selectivity curves (Fig. 1). Efficiency curves can be plotted for the percent of mass in a specific particle size class in feed stream which is recovered into either coarse or fine streams. The two types of curves are complementary.
