Electrostatic charges are created inside a powder during a flow.
This appearance of electrical charges is due to the triboelectric effect, which is a charge exchange in the contact between two solids.
During the flow of a powder inside a device (mixer, silo, conveyor, etc.) the triboelectric effect occurs in the contact between the grains and in the contact between the grains and the device.
Therefore, the characteristics of the powder and the nature of the material used to build the device are important parameters.
