Drum Type Shot Blasting Machine is suitable for small, flat and light workpiece shot blasying. It has specially designed rotary barrels. This series main feature is the geometry of the rotating tub. The inner wall of the cylinder is provided with a specially shaped ridge and the bottom is shaped into a triangular pyramid shape. This unique design creates an innovative overturned action. When the drum rotates, the ridge on the inner wall of the roll acts to flip and mix the workpiece. Whole the pyramid moves the workpiece at the bottom of the barrel to the top of the material. This muti-turn action ensures that the Shot Blasting Machine can cover all the surface of the workpiece, resulting in a uniform shot blasting effect. Treatment effect is bright and clean parts surface, no sediment, rust or scale.
