| 摘要 |
The invention relates to a device for accelerating abrasives, comprising a centrifugal wheel (8) that is driven to rotate about an axis of rotation. Said centrifugal wheel further comprises blades (2) that are disposed in a substantially radial orientation relative to the axis of rotation, and a lateral disk (4) on which the blades (2) are retained with a lateral edge. A feed line (6) for the abrasive has an opening (7) that is contiguous with the free edges of the blades (2) of the centrifugal wheel (8) outside the axis of rotation of said centrifugal wheel (8). The inventive device is further characterized in that the blades (2), on the side facing the feed line (6), have recesses (3) that are opposite the opening (7) of the feed line (6).
