Abstract
A process and apparatus for the mixing of material by means of the combination of sheer-dispersion and/or extensional-dispersion and distributive mixing actions, in which the mixing occurs in one or more stages within stress inducing flow channels between movable members whereby the material is essentially propelled through the flow channels of such stages by pumping actions provided by the relative movement between the members within the mixer itself.
Claims33
A mixing apparatus for mixing a material, the apparatus comprising one or more stress inducing flow channels and at least two members eccentrically mounted one within the other so as to define a chamber therebetween, and which are rotateable relative to one another to thereby produce a pumping force to force material through said flow channels and chamber to thereby subject the material to stresses within at least one of said flow channels and said chamber that results in at least an extensional-dispersive or a shear-dispersive mixing.
A mixing apparatus according to claim wherein at least some of said flow channels are provided with valve means which favor flow in the downstream direction.
Apparatus for mixing a material, the apparatus comprising one or more flow channels defined by each of at least two channel defining members which are axially mounted within a housing,
- at least one of said flow channels being a stress-inducing flow channel,
- at least one of said channel members being rotateable on a shaft which extends to the other such that a chamber and an enclosing volume is defined between the two channel members around said shaft and an inner surface of said housing,
- one of the channel members being provided with one or more partition members extending between the two channel members to partition said chamber into two or more compartments,
- and wherein said channel members have non-parallel facing surfaces such that as the rotating channel member rotates, a respective volume of each compartment progressively increases and decreases as a function of its annular position about said shaft.
