ELECTRODE FOR POWDER TRANSPORT WITH GUIDE ON ELECTRO- STATIC POWDER TRANSPORT DEVICE

摘要

PROBLEM TO BE SOLVED: To prevent occurrence of dispersion to vary discharge irregularly in relation to power particulates to be transported and a material of a guide wall when the guide walls are provided left and right of a passage of an electrode for powder transport. SOLUTION: The guide wall 2 raised higher than a passage surface is provided along a passage 3 through which electrified powder particulates pass, and a material of the guide wall 2 is made not to electrify the powder particulates or to restrain electrification extremely small even when the powder particulates make contact with the guide wall 2.
