The electrostatic charging trends and signal frequency analysis of a particulate material during pneumatic conveying

The charging of particulate materials due to contact with the inside surface of a pipeline wall (triboelectrification) during pneumatic conveying is common in bulk solids handling equipment. Electrostatic discharge from particulate materials in a transport line can lead to fire and explosion hazards. Conversely, the phenomenon of electrostatic charge can be utilized to measure particle flow. At present there is only a very limited amount of...
