The paper deals with experimental research of the waste suspensions mixing from the energy industry. Mixing experiments were carried out in a transparent baffled vessel with a diameter of 290 mm. Standard pitched six-blade turbine and folded four-blade turbine with diameters of 100 mm in two relative distances from bottom H2/d = 1 and 0.5 were used in experiments. Measurements were carried out with three volumetric concentrations of suspensions: 16, 31.5 and 47%.
