Close Loop Hanger Shot Blasting Machine

ABRABLAST CLOSE LOOP HANGER SHOT BLASTING MACHINE

ABRABLAST Close Loop Hanger Shot Blasting Machine is a highly efficient, automated surface cleaning system designed for handling large, heavy, or complex-shaped work pieces.
Equipped with an enclosed loop hanger conveyor, this machine allows for continuous loading, blasting, and unloading without the need for manual intervention, making it ideal for high-volume production environments.
This machine excels at removing rust, scale, paint, and other contaminants, providing a clean,uniform surface finish. It is used in industries such as automotive, foundry, metal fabrication, and heavy machinery, where precision and consistency in surface preparation are critical.

Operations :

  1.  Close Loop Hanger System: The closed-loop overhead conveyor system provides continuous circulation of work pieces through the blasting chamber, ensuring uninterrupted processing and reduced cycle times.
  2. Automated Loading &amp: Unloading: The system automatically loads and unloads parts from the hangers, allowing for minimal manual handling and improved efficiency.
  3. Complete Surface Coverage: The rotating hangers expose all surfaces of the workpieces to the abrasive stream, ensuring uniform and consistent surface treatment.
  4. High-Performance Blast Wheels: Multiple high-powered blast wheels effectively remove rust, scale, and other contaminants, providing a clean, smooth surface ready for further processing or coating.
  5. Durable Construction: Built with high-strength, wear-resistant materials to withstand harsh industrial environments and ensure long-term reliability.
  6. Advanced Control System: Equipped with a user-friendly PLC-based control system for precise operation and easy integration with existing production lines.

Finishing Process and Application :

The Close Loop Hanger Shot Blasting Machine is versatile and used in various industries for surface cleaning and preparation:
  • Automotive:Cleaning and preparation of parts such as chassis, engine blocks, and axles before painting or coating.
  • Heavy Machinery:Surface treatment of large castings, gears, and other heavy components to improve durability and surface finish.
  • Foundries:Cleaning of cast iron, aluminum, and steel parts for improved surface quality and defect detection.

How It Works

The Close Loop Hanger Shot Blasting Machine operates by suspending workpieces on hangers attached to the overhead conveyor. These hangers move continuously along a closed loop, entering the blast chamber for surface treatment. As the workpieces rotate, high-velocity abrasive media, propelled by powerful blast wheels, removes surface contaminants such as rust, scale, paint, and debris.

After the blasting cycle, the conveyor transports the cleaned parts out of the blast chamber for automatic unloading. The machine's built-in abrasive recycling system collects and recycles the media, ensuring cost-effective operation and minimal waste.

Advantages

  1. Continuous Operation: The closed-loop conveyor system ensures continuous blasting, reducing downtime and increasing production capacity.
  2. Uniform Surface Treatment: The rotating hangers allow for 360-degree surface coverage, providing even cleaning and preparation on all sides of the workpieces.
  3. Reduced Labor Costs: Automated loading, blasting, and unloading minimize the need for manual handling, reducing labor costs and increasing productivity.
  4. High Throughput: Designed for high-volume operations, this machine is perfect for industries requiring fast, consistent, and efficient surface preparation.
  5. Cost-Efficient Operation: The system’s ability to recycle abrasive media reduces material costs, while its durable design minimizes maintenance requirements.
  6. Customizable Configurations: Available in various sizes and configurations, the machine can be tailored to meet specific production needs and part dimensions.
