'''Abstract''':
a powder treatment system with variable speed of rotation of a treatment vessel containing the powder at different stages of the treatment process. during treatment stages where gas flow may be present (e.g., pump down), the treatment vessel is spun at a centrifugal speed in order to confine the fine powder particles within the treatment vessel and prevent or substantially minimize elutriation losses. during treatment stages where gas flow may be minimal or not present (e.g., treatment dwell time), the rotational speed of the treatment vessel is a cataracting speed in order to uniformly treat the fine powder particles whilst avoiding or substantially minimizing elutriation losses. a movable comb can be moved from a first position not in contact with the particles confined against the inner surface of the treatment vessel during rotation of the treatment vessel at a centrifugal speed, to a second position that encourages separation of the particles from the inner surface of the treatment vessel and breaks up agglomerates during rotation of the treatment vessel at a cataracting speed.
