device and its use for schleuderstrahlen with dry ice

摘要

Device for the spinning beams of sensitive blasting media, in particular dry ice, with a rotating centrifugal wheel (1), the distributed over the circumference of the thrower blades (14), which are arranged in the middle region of the impeller wheel, with the centrifugal wheel rotating acceleration sleeve (12) and a feeding device (3) for feeding of the blasting material into the acceleration sleeve (12), wherein the introducing a pre-acceleration sleeve (15), a widened toward the blower wheel rolling operation for the axial and radial pre-acceleration of the abrasive blasting material to be supplied to the centrifugal wheel (1), characterized in that the acceleration tube, as a cylindrical annular body is formed which, with radial through openings (23) is provided.
