The mathematical model of separation of inhomogeneous fluid systems in centrifugal force field is adapted to viscoplastic fluid purification in a cylindroconical hydrocyclone by pressure flotation process. The model takes account of the action of inertial and Coriolis forces and associated mass of fluid. The system of partial differential equations describing the flotation process is reduced to a system of ordinary differential equations and solved numerically taking account of the geometry of the working space of the cylindroconical hydrocyclone. Based on the developed mathematical model, the influence of the separation factor on the residual concentration of the solid phase particles at different values of the cone angle of the body and the plasticity number was analyzed. Physical justification of the results is enunciated. The obtained results can be used to design equipment for viscoplastic fluid separation in hydrocyclone by pressure flotation.
