REDUCTION OF ELECTROSTATIC CHARGING OF PARTICLES IN PNEUMATIC CONVEYING

摘要

Tribo-electrification of conveyed particles in a pipeline of a pneumaticconveying system is reduced by electrically isolating at least one portion of the innersurface 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 theconveyed particles.
