How to Eliminate Electrostatic Charging of Powder Processing Equipment

Powder processing operations can generate vast quantities of electrostatic charge via the movement of powder.

The standard method of charging on powder processing operations is due to triboelectrification, which is basically the contact and separation of the powder with processing equipment, the powder itself or other factors that can cause charging, like surface contaminants.

If the powder is being discharged into a blender or mixer that contains a solvent, the MIE of the hybrid atmosphere could be much lower such that the initial ignition of the solvent vapour could propagate a combustible dust deflagration.
