Curve-blade blast wheel is designed for the development of heavy-duty shot blasting machine, large castings and forgings tend to increase the size of the ordinary shot blasting machine does not have the large jetting of long-range jet cleaning capacity, the surface of the blade design using the initial shot The principle of rotation makes the pellets rate of the projectile greatly increased, the projectile speed is faster, the area of the projectile is large, the projectile is easy to clean and so on. It is suitable for the large-scale structural parts, large-scale casting and forging long-distance projectile cleaning and shot blasting.
