ABSTRACT:
A shot blasting machine is arranged for simplicity in servicing and for efficiency in operation. The number of vanes in the blast wheel is equal to the number of blades in the impeller, and the connector to connect the blast wheel to the drive hub is arranged so that the timing of the wheel is the same regardless of the orientation of the connector with respect to the drive hub and the impeller. The control cage is of a large diameter, with commensurately large impeller, so the vanes can be installed through the central opening of the wheel. Further, the vanes slide into grooves in the blast wheel, frictionally held by leaf springs, and restrained by stops in one direction only.
