Abstract
A centrifugal wheel assembly includes a disc-type guide wheel having a rotary axis; and a plurality of impeller vanes oriented radially with respect to the guide wheel. Each impeller vane has oppositely located particle propelling surfaces of identical shape. Each impeller vane has a longitudinal axis and a transverse axis oriented perpendicularly to the longitudinal axis. Both axes are contained in a central plane passing through the impeller vane and oriented parallel to the particle propelling surfaces. The impeller vane is symmetrical with respect to both axes. Each impeller vane further has recesses at its mid length; the recesses are arranged symmetrically with respect to both axes and receive clamping elements for releasably fastening each impeller vane to the guide wheel.
