The design process, using a slow drive roller chain drive and enhance the struggle of the rotation cycle of the experimental use of the projectile. In order to remove residual casting or forging the surface of sand or iron oxide with a high-speed rotation of the impeller Pillay will continue to turn within the projectile thrown to the drum parts. Required to achieve the following purposes: a comprehensive use of mechanical and electrical knowledge; b projectile design cycle and the separation device; c filter design; d shot cycle and separation equipment, dust collector parts of the design. Using a gear-driven shot blast wheel drum work, while the use of dry-type dedusting cyclone dust separation device work. Projectile loop device of roller retaining plate in between the spiral shell with a separate screen to upgrade the Big Dipper and composition. Firing projectiles thrown by the impeller workpiece, the roller retaining plate from the grid plate and the cylinder bore into the shell protecting the gap between the have, the use of screw rotation to enhance the role of flow within the bucket. Elevated to the top, through the separation screen deburring, nails, core bone, sand, grain and so on. Complete projectile shot by the import into the canal inside. Designed for small batch parts cleaning work, there is a good practical value and economic benefits. Design object for the assembly, projectile circulation and separation devices, filter design, promotion fight. This machine is used with a unique location from workshop dust collection equipment installed wind pipe with good sanitary conditions restrictions, this machine is equipped with automatic stop device, easy to operate.
