How It Works: Airless Tunnel Type Shot Blasting Machine

A tunnel-type shot blasting machine operates on the principle of high-speed abrasive particles impacting the surface of the workpiece to achieve various surface preparation objectives such as cleaning, descaling, deburring, and surface finishing. Here’s a step-by-step breakdown of its operation:

  1. Loading and Transport System: Workpieces are loaded onto a conveyor system that moves them through the tunnel type shot blasting machine. The conveyor speed can be adjusted to control the exposure time of the workpiece to the blasting operation.
  2. Blasting Chamber: As the workpieces enter the blasting chamber, they pass beneath multiple blast wheels strategically positioned around the chamber. Blast wheels are equipped with high-speed impellers that propel abrasive media, such as steel shot or grit, toward the surfaces of the workpieces.
  3. Abrasive Media Propulsion: The abrasive media, accelerated by the blast wheels, impacts the workpiece surfaces at high velocities. This impact removes scale, rust, old paint, and other contaminants from the workpiece surface, preparing it for subsequent processes like painting or coating.
  4. Dust Collection and Recovery: Simultaneously, a powerful dust collection system removes the dust and debris generated during the blasting process. The collected abrasive media and debris are separated, with the reusable abrasive media being recycled back into the system for continued use.
  5. Workpiece Exit and Unloading: After passing through the blasting chamber, cleaned and prepared workpieces exit the machine. They may proceed to additional processing stages or be unloaded for further inspection or packaging.
