A media drum incorporates an inner and outer cylinder, having a helical vane located generally intermediate thereof, with the media drum being supported upon a base, and its bearings, and motivated into rotation by a drive motor. The media drum integrally contains two parts, an entrance segment, and an exit segment. At the exit segment a cooling component, in the form of a liquid spray, is either directed into the drum, or into a jacket surrounding the exit segment of the drum, for cooling of the castings, media sand, abrasive members, to achieve a rapid cool down of these various components during usage of the apparatus. A reservoir is provided for collecting any excess liquid coolant, and a steam jacket surrounds the drum for collecting any generated steam for its removal.
