Abstract
Apparatus and method for degassing fine powders of metals are disclosed. A vertical shell having a series of baffle plates inclined at an angle of repose is used to induce a serpentine path for the powder. The shell is subjected to suitable conditions of vibration temperature and pressure to maintain the desired flow rate and gas separation. Conditions of mesh size, pressure temperature, angle of repose as well as equipment configuration are discussed.
