Abstract (en)
A rotary impeller wheel for blast cleaning apparatus comprises a blade mounting plate (20) having a central aperture (30) and a plurality of radially extending slots (34) opening into the aperture. Each slot (34) is adapted to receive a blade (18) for throwing of abrasive medium, each blade (18) having a lug (50) extending along part of one side edge, and the cross sections of the slots (34) and the lugs (50) being complementary. The length of the lugs (50) is such that the lugs (50) can enter the slots (34) from the central aperture (30) and the complementary cross sections are such that the blades (18) are retained in the respective slots in an axial direction.
