Abstract: A workpiece cleaning mill that is useful for cleaning castings includes a hollow housing that is established by arranging plural elongated manganese flights side-by-side to establish a cylinder, and attaching the flights to opposed entrance and exit rings. A feed conveyor feeds workpieces into the entrance end, and an exit conveyor conveys the workpieces away from the exit end. Media throwers are disposed at each end to throw high-speed cleansing media, such as shot, into the housing. The housing is rotated as the workpieces move, under the influence of gravity and/or following workpieces being fed into the housing, from the entrance end to the exit end while being bombarded with shot. Steel mesh curtains at each end block the media from passing outside of the mill. Spent media falls through perforations in the flights, and the spent media is conveyed back to a media hopper and thence to the media throwers for reuse. Magnetic valves regulate the amount of media thrown by the throwers.
