Abstract
A centrifugal blasting apparatus is configured to deliver friable media without destroying a large percentage of the delivered media. The centrifugal blasting apparatus includes a compressed air feed system that intermixes and fluidizes blast media with compressed air and delivers the fluidized blast media to a blast wheel. The control cage is formed with rounded interior surfaces to avoid sharp transitions that may otherwise fracture the media. The blades are curved to maximize accelleration of the blast media with the lowest possible rotational rate. The first edges of the blades, adjacent the axis of rotation, are configured to receive the blast media. Specifically, the first edges are rounded to minimize the amount of blast media that is broken by using a sharp leading edge. The channels on the blades themselves are also polished to minimize the amount of blast media that is broken while traveling along the surface of the blades.
