<p>Disclosed is a agitator (1; 1a-1h), particularly for abrasive media, comprising a support disk (2; 2a-2h) to which agitator blades (3; 3a-3h) are connected substantially perpendicular to the support disk (2; 2a-2h), said blades (3; 3a-3h) being arranged substantially in a radial direction. The support disk (2; 2a-2h) is also provided with a hub that receives an agitator shaft which is preferably motor-driven in a suitable manner. The trailing faces of the blades (3; 3a-3h) of the agitator (1; 1a-1h) and/or the area of the blade connections to the support disk (2; 2a-2h) is/are designed to largely prevent vortex shedding. For this purpose, preferred geometrical measures for the agitator blades (3; 3a-3h), the support disk (2; 2a-2h), and the connection of the blades (3; 3a-3h) to the support disk (2; 2a-2h) are disclosed and described.</p> |
