CFD-DEM simulations show triboelectrically charged particles can reverse direction in low-drag duct corner zones during pneumatic conveying, with the delay between feed pulses driving the effect more than pulse length.
Triboelectric separation turns contact electrification from a handling hazard into a deliberate sorting mechanism. This article covers how material pairs are selected by charge polarity, what feed moisture and particle size do to separation efficiency, and where the technique sits relative to density and optical sorting.
Single-contact electrification apparatus measures charge transfer from one controlled particle-surface or particle-particle contact, isolating a variable that bulk triboelectric and charge decay measurements can only report as an average.
