Regression equation for selection of design parameters and operating regimes of hydrocyclones used to separate suspensions by dual-stage flotation

A regression model is derived for the separation of nonuniform liquid systems with non-Newtonian properties by dual-stage pressure flotation in a film-flow regime created in the centrifugal force field in hydrocyclones. The regression model is presented in the form of a relationship between integral separation indicators in the cyclone and determining similitude numbers and rheologic properties of the dispersion medium. The model makes it possible to calculate with an accuracy sufficient for practical purposes the structural and regime parameters of cylindrical-conical and cylindrical hydrocyclones/flotation plants as a function of assigned integral separation indicators at the outlet from the vessel.
