This suggests that the semiinverted hydrocyclone has a different flow regime than the conventional hydrocyclone. As the hydrocyclone cuts coarser and the WS is lower at semiinverted positions, solids recovery to underflow decreases ( Fig. 14, Fig. 15, Fig. 16 ), especially for 42% solids at 135° position.

Mineral suspensions show Newtonian flow properties at lower solid concentration, but change into nonNewtonian regime as the solids content is increased. For Newtonian fluids viscosity is independent of shear rate, but for nonNewtonian fluids it varies with rate of shear.
