Diabola Tunnel Type Shot Blasting Machine

Diabola Tunnel Type Shot Blasting Machine is a specialized shot blasting system designed to handle cylindrical or elongated workpieces such as pipes, bars, rods, or shafts. It utilizes diabola-shaped rollers for smooth rotation and controlled movement of workpieces through the blasting chamber. This design ensures uniform surface cleaning, preparation, or finishing.

Key Features of a Diabola Tunnel Type Shot Blasting Machine

1. Diabola Rollers:
   • The rollers are diabola-shaped (tapered at both ends, wider in the middle) to securely hold cylindrical workpieces.
   • They allow 360-degree rotation of the workpieces as they move through the blasting chamber, ensuring even surface treatment.
2. Continuous Operation:
   • Workpieces are loaded at one end and travel through the tunnel in a continuous flow, making it ideal for high-production environments.
   • The system is automated, ensuring consistent and efficient processing.
3. Shot Blasting Process:
   • Abrasive media (e.g., steel shot or grit) is propelled at high velocity by blast turbines onto the rotating workpieces.
   • The process removes rust, scale, old coatings, and other contaminants or prepares the surface for coating or painting.
4. Closed Tunnel Design:
   • The blasting chamber is enclosed in a tunnel structure to contain abrasive media and prevent dust or debris from escaping.
   • A dust collection system ensures a clean environment.
5. Abrasive Media Recovery:
   • Spent media is collected, cleaned, and recycled for reuse, reducing operating costs and environmental impact.
6. Material Handling System:
   • The diabola rollers are part of a conveyor system that gently and securely transports cylindrical workpieces.
   • The design minimizes damage to the parts and ensures smooth movement.

Applications

The Diabola Tunnel Type Shot Blasting Machine is widely used in industries that require surface treatment of cylindrical or elongated parts:

1. Oil & Gas Industry:
   • Cleaning and surface preparation of pipes used in oil and gas transportation.
2. Automotive Industry:
   • Surface treatment of shafts, axles, and other cylindrical components for coating or painting.
3. Steel Industry:
   • Descaling and cleaning of metal rods, bars, and tubes before further processing.
4. Construction:
   • Preparing steel pipes and rods for structural applications, including reinforcement bars.
5. Pipeline Coating:
   • Preparing pipelines for anti-corrosion coatings or painting.

Advantages

1. Uniform Surface Finish:
   • The diabola rollers ensure 360-degree rotation of the workpieces, achieving even surface treatment.
2. High Throughput:
   • Continuous operation allows for the efficient processing of large volumes of parts.
3. Versatility:
   • Accommodates workpieces of various diameters and lengths.
4. Cost-Efficiency:
   • The media recovery system minimizes wastage, and the automated operation reduces labor costs.
5. Compact Design:
   • Tunnel-type machines are space-efficient, suitable for production lines with limited floor space.
6. Environmentally Friendly:
   • Dust collection and abrasive recycling systems ensure clean, eco-friendly operations.

Process Flow

1. Loading:
   • Workpieces are placed on the diabola rollers, which adjust to their diameter.
2. Rotation & Blasting:
   • As the rollers rotate the parts, abrasive media is blasted onto the surface, ensuring complete coverage.
3. Abrasive Recovery:
   • Used media and debris are collected, separated, and cleaned for reuse.
4. Dust Collection:
   • Dust and fine particles are removed to maintain air quality and prevent contamination.
5. Unloading:
   • Finished workpieces exit the machine, ready for further processing or coating.
