摘要： The invention is directed to a corona charging device having a powder feed with an outlet. The device has an internal charging cavity having an inlet and a charged powder outlet. The powder feed outlet is positioned at the internal charging cavity inlet. The device is adapted to guide a powder stream downstream from the powder feed outlet to the charged powder outlet. The device also includes a corona charger having one or more needle projections (each having a tip) positioned and adapted to facilitate a corona ion flow from the needle projections and intersecting the powder stream. The device also includes a rotating ground electrode adapted to be charged or grounded to attract the corona flow from the needle projections, and to rotate segments of the ground electrode between the internal charging cavity and a ground electrode cleaner.
