Abstract
A rotating processing vessel and a method of using a magnetically coupled agitator which does not penetrate the vessel walls to mix dry or moist powders within the rotating processing vessel.
Claims18
A method of mixing a powder in a processing vessel comprising:
- providing a processing vessel constructed of a substantially non-magnetic material comprising a shell, a closed cover and a closed main valve,
- providing one or more powders to be mixed,
- opening either said cover or said main valve,
- placing said one or more powders to be mixed within said vessel through said opened cover or said opened main valve,
- closing said opened cover or said opened main valve such that said vessel contains one or more powders to be mixed,
- rotating said vessel about its axis by means of a power source located externally from said vessel,
- rotating an agitator within said rotating vessel by means of a magnetic coupling between said agitator and a second power source located externally from said rotating vessel,
- rotating said vessel and said agitator within said rotating vessel until said one or more powders are mixed,
- shutting off said second power source and stopping the rotation of said agitator,
- shutting off said first power source and stopping the rotation of said vessel about its axis,
- opening said main valve, and
- discharging the mixed one or more powders through said opened main valve.
