	Critical impeller rotational speeds for having a solid suspension in a liquid and for gas dispersion in the slim vessel with two independently driven impellers were determined. An A-315 impeller functioned as the lower impeller whereas a Rushton turbine was fixed higher with gas being fed right below the latter. We investigated what influence on this rotational speed was had by the distance between the impellers, their rotational direction, solid concentration, solid particle size and gas flow rate. Results obtained for the twoand three-phase systems were compared. In the three-phase systems, we also measured the power input in order to assess the efficiency of mixing.
