  • Patent number: 4994231
    Abstract: A blending/loading system wherein an elongated cylinder or fuel rod is positioned on a turntable underneath a series of hoppers containing the particulates to be blended/loaded. Separate transfer tubes from each hopper are aligned with the cylinder and are subsequently lowered into the cylinder. Upon lowering, the cylinder is rotated and nozzles at the ends of the transfer tubes are activated to discharge, disperse and mix the stored particulates into the rotating cylinder. As the cylinder fills up, the transfer tubes are withdrawn from the rotating cylinder until the desired amount of fill is reached. Afterwards, the nozzles block any additional flow from occurring as they are raised out of the cylinder.
