A pressurized feeder vessel feeds powdered material into a stream of propellant gas. The feeder vessel includes a funnel-shaped hopper that is resiliently suspended by an elastic member inside the vessel. A vibrator such as an electric motor with an eccentric weight on its shaft vibrates the bottom end of the hopper. The vibration forces of the vibrator are preferably transferred to the hopper via a flexible diaphragm. The hopper is thus subjected to primary vibration forces and torques from below, and secondary, reaction vibration forces and torques fro...
An arrangement for delivering powdered material under pressure comprising: A. a source of pressurized propellant gas; B. a pressure vessel that is connected to the source of pressurized propellant gas via a pressure inlet and that has a pressurized outlet; C. a mainly funnel-shaped hopper that is mounted within the pressure vessel, that holds the powdered material, and that has a top portion and a bottom portion; D. an inlet orifice through which the powdered material exits the hopper and enters the pressurized outlet line; E. a suspension resiliently su...
