- Entry into Blast Chamber: Once loaded, the hangers transport the components into the sealed blast chamber. In Y-hanger or continuous systems, this movement is typically automated. For door hanger types, the door is closed manually or automatically after loading.
- Abrasive Projection: Inside the chamber, one or more high-speed blast wheels are strategically positioned. These wheels, equipped with rotating blades (vanes), centrifugally accelerate abrasive media (shots) towards the suspended components at high velocity. The impact of these shots removes contaminants like rust, scale, paint, and burrs, simultaneously imparting a desired surface profile.
- Component Rotation: As the blasting occurs, the hangers typically rotate, exposing all faces and contours of the components to the abrasive stream. This ensures uniform cleaning and prevents blind spots.
- Abrasive Reclamation and Cleaning: After impacting the components, the abrasive media falls to the bottom of the blast chamber. It is then collected by a screw conveyor system and transported to a bucket elevator. The elevator lifts the abrasive to an air wash separator, which separates reusable abrasive from dust, broken media, and other contaminants. Clean abrasive is then stored in a hopper, ready to be recycled back to the blast wheels.
- Dust Collection: A powerful dust collector system is integral to the operation. It maintains negative pressure within the blast chamber, drawing out airborne dust and fine particles generated during the blasting process. This ensures a clean operating environment and compliance with environmental regulations. The collected dust is then deposited into a waste bin.
- Unloading: Once the blasting cycle is complete, the hangers exit the blast chamber. The cleaned components are then unloaded, ready for the next stage of their manufacturing process.
The entire process is designed for maximum efficiency, safety, and environmental responsibility, making the hanger type shot blasting machine a robust solution for surface preparation.
