10 October 2026Cyclone Separation of Fine Powders: Cut Size, Efficiency Curves, and Agglomeration
The classical cyclone cut size model assumes discrete, non-agglomerating particles. Cohesive or moisture-sensitive fines can travel through a cyclone as agglomerates instead, which changes what a PSD result actually tells you about classifier performance.
