The paper deals with the results of experiments on the mixing phenomena in a vessel with different impellers. The flat-bottomed vessel was equipped with Rushton turbines, six flat blade turbines and six pitched down blade turbines. The mixing time related to both, the vessel construction and the rheological properties of the liquid stirred, has been analyzed. The best impeller-tank system, taking into account the process efficiency, has been proposed.
