Abstract
An agitator, particularly for abrasive media includes a support disk to which agitator blades are connected substantially perpendicular to the support disk. The blades are arranged substantially in a radial direction. The support disk also includes a hub that receives an agitator shaft which is preferably motor-driven. The trailing faces of the blades of the agitator and/or the area of the blade connections to the support disk are designed to largely prevent vortex shedding. This is accomplished by implementing a specific geometry for the agitator blades, the support disk, and the connection of the blades to the support disk.
