ABSTRACT:
A centrifugal blasting apparatus including an improved blast wheel and an improved deflector. The blast wheel comprises a flat disk and a plurality of vanes attached to the disk and spaced equiangularly from each other. Each of the vanes is composed of a first face having a substantially right-angled triangle configuration and a second face of substantially triangular configuration. The second face extends from the hypotenuse of the first face farther off the axis of rotation of the blast wheel than the first face and slants laterally and backwards with respect to the direction of rotation of the blast wheel. The deflector has a feed slot extending through the peripheral wall thereof. The feed slot is substantially parallelogram shaped. Such a blasting apparatus can present a regular and widened blast pattern having a uniform distribution of abrasive particles, thereby giving a desirable even processing to the workpiece.
