Particle Size Classifier for the Subsieve Range - NASA/ADS
1963-9-1 · A particle size classifier for dry powders in aerosol form, based on the combined classifying mechanisms of impaction, adhesion, and the characteristic trajectories of particles, has been developed and extensively tested with a variety of powders. Continuous classification has been achieved for powders the diameters of which are predominantly below 50 μ by impacting
