Shot blasting is a widely used surface preparation process in industries like automotive, foundry, railways, aerospace, shipbuilding, and construction. But did you know that not all shot blasting machines are the same?
Different machines serve different purposes, depending on the shape, size, and material of the workpiece. Choosing the right machine ensures better efficiency, cleaner surfaces, and longer equipment life.
At AeroWheel Surface Finishing, we provide a range of shot blasting machines tailored to specific industrial needs. In this blog, we’ll walk you through the major types of shot blasting machines and where each one fits best.
What Is a Shot Blasting Machine?
A shot blasting machine is an industrial system that uses high-speed abrasive media—usually steel shots or grits—to clean, roughen, or strengthen metal surfaces. The goal is to remove rust, scale, old paint, or other contaminants and to prepare the surface for further processing like painting, powder coating, or welding.
1. Tumblast Shot Blasting Machine
How It Works:
Components are loaded into a drum or conveyor-type chamber. As the drum rotates, the parts tumble over each other while shots are blasted from a turbine.
Best For:
- Small to medium-sized components
- Mass production
- Automotive parts, castings, and forgings
Advantages:
- Batch processing
- Uniform cleaning
- Cost-effective for high-volume production
2. Table Type Shot Blasting Machine
How It Works:
Workpieces are placed on a rotating table inside the blast chamber. The table turns slowly while shots are directed onto the surface.
Best For:
- Flat or heavy components
- Engine blocks, gear housings, die castings
Advantages:
- Ideal for components that cannot tumble
- Simple operation
- High cleaning quality for large flat parts
3. Hanger Type Shot Blasting Machine
How It Works:
Parts are hung on rotating hooks or hangers and blasted while suspended. These machines can be monorail or batch type.
Best For:
- Large, fragile, or irregular-shaped parts
- Welded assemblies, chassis, frames, cylinders
Advantages:
- No collision between components
- Suitable for delicate or complex parts
- High throughput in automated lines
4. Continuous Conveyor Type Shot Blasting Machine
How It Works:
Parts move continuously through the blast chamber on a conveyor belt. Turbines blast the parts from multiple angles as they pass through.
Best For:
- High-volume production lines
- Sheet metal, profiles, structural steel components
Advantages:

How to Troubleshoot Common Issues with Shot Blasting Machines
- Fast processing
- Ideal for in-line production
- Minimal handling required
5. Roller Conveyor Shot Blasting Machine
How It Works:
Large workpieces are placed on rollers and transported through the blast chamber. Often used in steel processing units.
Best For:
- Plates, beams, angles, pipes, and large profiles
- Shipbuilding, construction, heavy engineering
Advantages:
- Continuous cleaning of long or flat items
- High production capacity
- Excellent for surface descaling before painting
6. Spinner Hanger Shot Blasting Machine
How It Works:
Individual parts are loaded on hangers and rotated during blasting for uniform surface coverage.
Best For:
- Parts that require all-around coverage
- Valves, pumps, engine blocks
Advantages:
- Precision cleaning
- Flexible for batch and varied shapes
- Minimizes part damage
7. Portable Shot Blasting Machine
How It Works:
A mobile unit manually operated by a technician. Abrasive is propelled through a hose and nozzle toward the surface.
Best For:
- On-site cleaning
- Tanks, bridges, pipelines, and field jobs
Advantages:
- Portable and flexible
- No need to move heavy components
- Suitable for spot repairs and maintenance
How to Choose the Right Shot Blasting Machine
Your selection should depend on:
- Size and shape of your components
- Production volume (batch or continuous)
- Level of cleaning or surface finish required
- Material handling preference (manual vs. automatic)
