How to manage electrostatic problems in bulk solids processing
Electrostatic charge generated in bulk solids processing can lead to handling, quality, and safety problems. This article will help you understand electrostatic charge, including how it's generated and the consequences it can have on a processing operation. How to manage these problems using both natural mechanisms and neutralization devices is also explained.
Particles -- especially powders -- are very susceptible to electrostatic charge. The effects of electrostatic charge on particles during processing can lower productivity and product quality, as well as create safety hazards. For example, attraction and repulsion caused by electrostatic charge in particles can impede screening and separation processes and change the density and flowability of the particles. The sudden discharge of accumulated electrostatic charges can harm personnel, damage system electronics, and increase fire and explosion hazards.
