Abstract
Method and apparatus are shown for feeding particulate material into a pressurized container. A rotor is located within the pressurized container, and the rotor hub is connected to a combination drive and material supply tube which extends through a wall of the container in fluid-tight engagement therewith. Particulate material from an unpressurized supply source outside the container is fed to the rotor through the supply tube, and is discharged through radially extending flow passages formed in the rotor. Means are provided for restricting the flow of particulate material at the discharge end of the flow passages such that material flowing therein is compacted by centrifugal acceleration to substantially prevent flow of fluid from the pressurized container through the supply pipe while continuously supplying particulate material to the container.
