  • Performance analysis and design of filtering hydrocyclones SciELO

    As well as the changes in the volumetric feed flowrates, the filtering hydrocyclones had new values for the Euler numbers, as can be seen in Figure 7. Within the limits of the experimental region studied in this work, Rietema's filtering hydrocyclones had higher Euler numbers than the conventional device, while the Bradley's.

  • Hydrocyclone Wikipedia

    A hydrocyclone is a device to classify, separate or sort particles in a liquid suspension based on the ratio of their centripetal force to fluid resistance. This ratio is high for dense (where separation by density is required) and coarse (where separation by size is required) particles, and low for light and fine particles.

The main feature of the novel hydrocyclone was that the fines content in the fine fraction was substantially lower due to a lower thickening of the coarse fraction. This resulted in considerably lower SR values of the fine fraction, but also higher.
