TUNNEL TYPE SHOT BLASTING MACHINE

ABRABLAST Tunnel Type Shot Blasting Machine is a highly efficient solution for continuous surface treatment of large quantities of workpieces. Designed for mass production environments, this machine excels in cleaning, deburring, descaling, and surface preparation of long, flat, or irregular-shaped components. Its tunnel design allows parts to move through the blasting zone on a conveyor belt or roller system, ensuring consistent and thorough cleaning. Commonly used in industries such as automotive, construction, shipbuilding, and steel fabrication, the Tunnel Type Shot Blasting Machine offers exceptional performance with minimal manual intervention, making it a cost-effective choice for high-volume production.

Operations :

  1. Continuous Operation: Designed for non-stop, high-speed processing, ideal for mass production facilities.
  2.  Tunnel Design: Parts are fed into the machine through a conveyor, ensuring a smooth and efficient flow from loading to unloading.
  3. Powerful Blast Wheels: Equipped with multiple high-power blast wheels that direct abrasive media uniformly across all surfaces of the workpiece.
  4. Customizable Conveyor System: Flexible conveyor configurations (roller, belt, or chain conveyor) to suit various part sizes and production needs.
  5. Durable Construction: Built with high-grade wear-resistant materials, ensuring long- term durability and low maintenance costs
  6. Automated Operation: Integrated with advanced PLC control systems for easy automation, ensuring consistent and precise control over the blasting process.

Finishing Process and Application :

The Tunnel Type Shot Blasting Machine is versatile and widely used in industries requiring high throughput and consistent surface treatment:
  • Steel & Metal Fabrication:Cleaning and surface preparation of steel plates, beams, profiles, and pipes.
  • Shipbuilding:Removal of rust and scale from large steel structures and ship components.
  • Construction:Cleaning of rebars, beams, and other steel structures used in construction.
  • Pipeline Industry:Surface treatment of pipes, tubes, and other cylindrical parts for corrosion resistance or coating.

How It Works

The Tunnel Type Shot Blasting Machine operates by continuously feeding workpieces into the tunnel via a conveyor system. As the parts move through the blasting zone, high-speed abrasive media is propelled by strategically positioned blast wheels, effectively removing rust, paint, mill scale, and other surface contaminants.

The continuous motion of the conveyor ensures uniform cleaning, while the powerful blast wheels provide high-speed treatment. Dust and spent abrasive media are collected by an advanced dust extraction and recycling system, maintaining a clean and efficient operation. Advantages

  1.  High Productivity: Continuous blasting operation allows for rapid processing of large batches of workpieces, increasing overall throughput.
  2. Uniform Surface Treatment: The tunnel design ensures that all parts are evenly blasted, resulting in consistent surface quality.
  3.  Energy-Efficient: Equipped with energy-efficient motors and blast wheels, reducing power consumption without compromising performance.
  4. Reduced Labor Costs: Automated operation reduces the need for manual intervention, streamlining production and minimizing labor costs.
  5. Environmentally Friendly: Built with an advanced dust collection system, ensuring compliance with environmental regulations and creating a safe working environment.
  6. Customizable: Available in a range of sizes and configurations, tailored to meet the specific needs of different industries and applications.
