Slurry viscosity calculation
Webb1 nov. 1996 · Classification in wet systems is also directly influenced by slurry rheology. In hydrocyclones (Kawatra, Bakshi et al., 1996; Tavares, Souza et al., 2002; Narasimha, Mainza et al., 2014), high-frequency screens (Mabote, Mainza et al., 2024) and screw classifiers (Fuerstenau and Han, 2003) the cut size significantly increases as the …

WebbFor non-settling slurries, the resultant slurry typically displays non-Newtonian behaviour, and its rheology and behaviour must be determined empirically to ascertain the work required by the pump. The pressure drop for these can then be calculated using established pressure drop calculations depending on the slurry viscosity and density ...
Webb5 mars 2024 · These equations are difficult to use in an actual case because the value of Re p depends on the terminal settling velocity. The following method gives a more workable solution. Equation (4.2-5) can be transformed into: CD ⋅ Re2 p = 4 3 ⋅ Rsd ⋅ g v2 l ⋅ d3. This factor can be determined from the equations above: nottinghamshire houses for saleWebbviscosity of the slurry under given solids fractions were predicted using the maximum solids fraction φm determined from the ηr-φ relationship.
