| Blasting media is fed centrally to a high speed rotating blast wheel. The centrifugal force, of the rotating wheel, throws the media at the components to be blasted at speeds up to 120 m/s. The design of the blades, insertion point, and the speed of the blast wheel determine the processing results in conjunction with the blasting media. In order to achieve an economic utilization of the blasting media, the amount of blasting media and the transfer to the blast wheel blades can be easily adjusted. The blasting media feed control can be optionally fully automatic. After the end of the shotblasting cycle, a shell valve closes the blasting media feed. Blasting media distribution and the setting of the blasting stream (hotspot) are accomplished externally in a user-friendly manner at the blasting media feed tube. If desired, the blast speed
