Beschreibung
Zusammenfassung:	An apparatus for the electro-kinetic charging of powder-like materials having a pair of supply channels, an input zone for each channel, one for the powder dispersed in a gas flow and one for another gas flow and which are shaped as dual annular nozzles with a pipe-shaped separating wall therebetween acting as an electrostatic ionizing electrode and made from an electrically semiconductive material having anti-sticking properties and, wherein the adjoining flow channel is formed as an annular channel by a pipe from an insulating material, and a centrally arranged rod, wherein the ratio between rod and pipe diameters is on the range from 0.75 to 0.9.
