Agitator for mixing liquids of different viscosities and liquids with complex rheological properties

Abstract

A mixer, especially for mixing liquid substances of different viscosities and liquids with complex rheological properties, equipped with a hub connected to mixing blades, is characterized by having an even number of mixing blades (1) permanently connected to the hub (2) and arranged symmetrically with respect to each other on the circumference of the hub (2), while a single mixing blade (1) has a first arm and a second arm forming an L-shape, wherein the first arm is attached to the hub (2) at an angle of 90 degrees and is shorter in relation to the second arm, and the second arm is inclined and has a rounded edge with a curvature defined by an ellipse with a dimension ratio of 1 / 2, wherein the second arm of each of the mixing blades (1) is directed alternately upwards or downwards in relation to each other.
