Apparatus for the determination of rheological properties of sedimenting suspensions

摘要

This invention relates to an apparatus for determining the rheological properties of sedimenting suspensions. More particularly, this invention relates to a method and apparatus which permits the accurate determination of the rheological properties of particulate suspensions in which the particles are settling. An apparatus for evaluating the rheological properties of sedimenting suspensions comprising: (a) a sedimenting suspension retainer; (b) a device means suspended in the retainer, the retainer and suspended device being capable of being rotated relative to one another, the device being permeable to the passage of particles settling in the sedimenting suspension, the suspended device being suspended in the sedimenting suspension in the retainer in the region having constant density.
