For the batch cleaning and surface finishing of castings and small assemblies and other components, 3Gn, 6Gn, 8Gn covered belt shot blasting machines are an ideal choice. The conveyor belt provides a turnover operation, so that all areas of the parts can be processed by the shot blasting flow, thereby ensuring that all cleaning is completed in one cycle. After the shot blasting cycle is over, the automatic reversal of the conveyor can unload the workpiece that needs further processing . All models of this equipment are self-contained, including automatic cleaning, collecting, separating shots and dust collection functions. No need for dedicated foundations or additional pipes. Large models can be added with automatic loading and unloading equipment to further improve efficiency.
