Abstract
Tribo-electrification of conveyed particles in a pipeline of a pneumatic conveying system is reduced by electrically isolating at least one portion of the inner surface of the pipeline, preferably the concave interior surface of at least one elbow. The isolated portion acquires an electric charge of opposite polarity to that of the conveyed particles.
