According to the cleaned workpiece weight, size, volume and production efficiency, can be artificial, mechanical or automatic feeding. The workpiece in the shot blasting cabin for tumbling, shot blasting cabin is made up of an annular groove belt and two covers from wear-resistant materials on the both end sides, the conveyor belt is provided with many guide bars, thereby ensuring the workpiece all surfaces are exposed and does not occur excessive collision during tumbling. After blasting abrasive containing burr, rust, or sand falls down through the rubber belt hole, and then transported to the bucket elevator and separator.
