Impeller
This machine resembles a long tank with a series of impellers or a single impeller attached to it. They can have an open flow of pulp between impellers or they can be joined cell to cell with barrage between them. A set up of froth flotation machine is shown in Fig. 13.12 (Krivoshapkina et al., 2019).

Hydrodynamics intensification and interface control in the flotation …
Impellers can be classified into three categories based on the flow patterns they create: radial impellers, axial impellers, and mixed impellers [27]. The radial impeller achieves mixing in a limited range via the main body convection diffusion and eddy diffusion, but the industrial application and experimental data analysis has indicated that ...

Coarseness of Particles in Flotation in Impeller-Type Cells
It is known that turbulence has a significant effect on the size of recoverable particles. The distribution of energy dissipation rate in cell volume (3 m 3) of RCS flotation machine was obtained in . Tests were carried out in series with RCS3 and RCS5 impellers. Total energy dissipation rate for the cell varied from 0.91 to 7.4 kW/m 3.
