  • POWDER HOPPER WITH QUIET ZONE, A COMBINATION OF A POWDER HOPPER AND A POWDER SPRAY GUN AND A METHOD OF OPERATING A POWDER HOPPER
    Publication number: 20140248437
    Abstract: A powder hopper is provided with a low turbulence zone for supplying powder to a spray gun. The low turbulence zone is defined by a baffle inside the hopper with the low turbulence zone being within a volume of the baffle, and an annular zone between the baffle and the hopper is used to bulk feed powder into the hopper. The low turbulence zone may alternatively be in the annular zone with powder added to the volume of the baffle. One preferred application for this hopper is in connection with the use of fine powder coating materials to coat the interior of small diameter cans.
