Abstract: An apparatus for feeding powder particles includes a hopper holding a supply of powder. A voltage supply is in electrical communication with a first electrode and a second electrode. The hopper is configured to drop powder onto the first electrode. The voltage supply is capable of producing an electric potential between the first electrode and second electrode and causing the powder particles landing on the first electrode to develop a surface charge. The second electrode is positioned remotely from the first electrode such that the electric field between the first electrode and the second electrode causes the powder particles that fall onto the first electrode to move off the first electrode and move toward the second electrode. The powder particles moving toward the second electrode may or may not reach the electrode, but in either case drop away from the second electrode due to the force of gravity.
