In a powder spraying apparatus the powder is brought into fluidized state within a pressure vessel and in a conveying main conduit. Fluidizing is accomplished by pressure fluid acting through a sinter metal bed in the vessel and through a perforated supplementary conduit in the main conduit. When a control valve is opened, powder will flow for atomizing and coating purposes in the manner of a liquid from the pressure vessel to spray guns. |
