The present invention provides a drum for a shot blasting apparatus that uniformly treats the works to be treated by increasing the level of agitation of the works that are buried at the bottom of the drum, and, further, suppressing the traces of collisions on the works, which traces are caused by the works colliding with each other. The present invention also provides the shot blasting apparatus using the drum. The drum comprises a hollow middle part, a lower-half part having the shape of a truncated cone, having a closed bottom, and having a projecting part for agitating that is connected to both the lower-half part and the middle part, and that agitates the works, wherein the projecting part for agitating has at least two surfaces, one being the surface for picking-up the works and the other being the surface for having the works slide down. The shot blasting apparatus of the present invention comprises, in addition to the drum for the shot blasting apparatus, a cabinet and a centrifugal injecting device wherein the cabinet comprises a sealing-wall member consisting of a ceiling-wall, a floor-wall, and both side walls, on the side of the opening of the cabinet. The cover is attached to the drum, and they can turn around as one body. |
