<p>Disclosed is a stirring member (1; 1a-1h), particularly for abrasive medi a, comprising a support disk (2; 2a-2h) to which stirring member 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 directi on. The support disk (2; 2a-2h) is also provided with a hub that receives a stirring shaft which is preferably motor-driven in a suitable manner. The tr ailing faces of the blades (3; 3a-3h) of the stirring member (1; 1a-1h) and/ or the area of the blade connections to the support disk (2; 2a-2h) is/are d esigned to largely prevent vortex shedding. For this purpose, preferred geom etrical measures for the stirring member 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> |
