The blast wheel disc riveted into one, constitute the impeller body. Impeller body is equipped with eight blades, impeller bodies packed together with the points located in the center of shot blasting round pill round Shotblast
In the motor-driven spindle. Hood is lined with a shield on the cover is equipped with directional sets and into the pill tube. Work, the projectile into the pill tube into the blast wheel. Projectile to get the initial velocity for synchronous rotation of the sub-pill round with leaves. Projectile flying out the window of the directed sets, thrown outside directed sets of high-speed rotating blades, the blade further accelerated by the projectile to the surface of the workpiece to be cleaning up. No vibration transfer to ensure the projectile to the leaves because points pill round and leaves for synchronous rotation, thereby reducing wear and tear on the blades.
