Abstract

The problem of non-Newtonian properties of a liquid during the suspension generation in agitated system is investigated. The tested agitator was the standard Rushton turbine. The impeller speed required for particle suspension increased with both the CMC solution concentration, u_CMC  and solid/liquid mass ratio in a suspension, U_s. Addition of the sodium chloride to CMC solution caused the decrease of the impeller speed required for suspension as well as stabilised both the CMC solution and the suspension properties.
