Abstract

A vibratory processing arrangement including an apparatus comprising three main stages. Namely, a high level waste vibrating impregnator, a vibrating calciner and a vibratory powder mixer. The waste impregnator comprises a downwardly inclined trough having flexible mountings and a vibrator at its upstream end, a hood structure and a series of liquid sprays connected to a high level waste supply tube. The vibratory calciner comprises a downwardly inclined tube connected to a downstream discharge tube. The discharge tube has an inlet pipe for entry of reducing gas. The reducing gas passes upwardly through the tubes to a gas discharge take-off tube near the upstream end of the downwardly inclined tube. A vibrator is tuned to provide the desired flow rate through the downwardly inclined tube. Calcined discharged powder falls downwardly into the vibratory mixer, which has a vibratory actuator and flexible mountings. Titanium powder is introduced into the vibratory mixer through a secondary inlet and is intimately mixed with the calcined discharged powder before being discharged into respective canisters.
