Mixing characteristics of industrial flotation equipment

Hydrodynamic Characterization of Industrial Flotation Machines Using Radioisotopes

“…In order to model a flotation bank of cells (Mavros, 1992;Yianatos et al, 2001Yianatos et al, , 2005a, the following equation has been used, …”

Roles of surfactant and fibres on fibre transport in a small flotation deinking column

“…The standard reactor model for flotation columns is the SmallLarge-Small-Plug (SLSP) [35], consisting in a series of one small, one large and one small (identical to the first one) continuous stirred tank reactors (CSTR) plus one plug flow reactor (PFR). In this model, the response to a conductivity pulse (see Appendix A for explicit equation development) is:…”

“…In addition to conventional CSTR and PFR models, the axial dispersion model can be effectively used to describe mixing in flotation columns [17,35,[37][38][39] with high aspect ratio (height/diameter) and interstitial liquid velocity to superficial gas velocity ratio [38]. The vessel dispersion number of the small flotation column used in this study was estimated using the equations proposed by Finch and Dobby [17] …”

Experimental study and mathematical modeling of the residence time distribution in magnetic mixer

“…The interpretation of RTD measurements may be realized by using compartmental models which are composed of the branches containing the elementary ideal reactors connecting all together by the nodes. The application of a mixing model (combination of a plug fl ow reactor (PRF) and a continuous stirred tank reactor (CSTR) with circulation fl ow) to study of RTD measurements is widely presented in the relevant literature [14][15][16][17] . From the experimental point of view, the non-ideal fl ow in the reactor may be estimated by means of the stimulus-response technique.…”
