Apparatus for blasting castings

摘要

The apparatus comprises one or more blasting cabins through which are conveyed workpiece carriers in the form of grate bars secured only at one end to a conveyor chain. A shifting device transfers workpieces from a first to a second conveyor for a second pass through such cabin. A turning device turns the workpieces over during such transfer. Said device comprises a box which is rotated about a horizontal axis and chutes each workpiece onto the second conveyor.
