Powder dustiness technical illustration comparing two transfer situations with the same PSD, showing how moisture history, agglomerate stability, and electrostatic effects change particle detachment and airborne dust release.

Square technical illustration for an Insight of the Week article on powder dustiness, showing a side-by-side comparison of the same powder transfer geometry under two different conditions. The left side shows a more grounded, conditioned state with stable agglomerates and limited particle detachment. The right side shows a drier, electrostatic condition with broken agglomerates, increased particle detachment, and greater airborne fine release, despite the same PSD.
