In daily workshop production, the wire mesh belt shot blasting machine is one very important equipment for continuous and stable surface cleaning.
Wire mesh belt shot blasting machine uses a stainless steel wire mesh conveyor belt to carry workpieces into the blasting chamber, and with multiple high-speed blasting turbines, it can remove rust, oxide scale, and sand very effectively.
How Wire Mesh Belt Shot Blasting Machine Works and Why Choose It?
Wire mesh belt shot blasting machine is a continuous pass-through type surface cleaning and finishing equipment. It uses a stainless-steel wire mesh conveyor belt to transport workpieces through a sealed blasting chamber. Inside the chamber, several high-speed blast turbines throw steel shots onto the surface to remove rust, oxide scale, paint, sand, and burrs, and also to strengthen the metal surface.
1. What Is a Wire Mesh Belt Shot Blasting Machine?
Wire mesh belt shot blasting machine is a pass-through type surface cleaning equipment. Workpieces are placed on the wire mesh belt, and the belt continuously sends them into the blasting area. Inside the chamber, the turbines throw steel shots with high speed to impact the surface. After blasting, the parts come out from the other side, already cleaned.
Because there is no tumbling and no collision, this machine is very suitable for flat, thin, or precision-type workpieces.
2. Main Structure of the Machine (Engineer Practical View)
A complete wire mesh belt shot blasting machine generally includes:
- Wire Mesh Conveyor Belt
Usually stainless steel or manganese steel mesh, strong wear resistance, stable conveying. - Blasting Chamber
Made with high-manganese wear plates, long service life under heavy shot impact. - Shot Blasting Turbines
Core component. Provides strong blasting force and large coverage area. - Abrasive Circulation System
Screw conveyor + bucket elevator + air separator to recycle abrasive automatically. - Dust Collector System
Cartridge or bag-type dust collector to ensure clean environment and remove fine dust. - Electric Control System
PLC control, belt speed adjustable, turbine protection, and fault monitoring.
This structure ensures the machine can run long time, stable, and efficient.

3. Working Principle (Simple and Clear Explanation)
- Place workpieces on the wire mesh belt.
- Belt moves and sends parts into the blasting chamber.
- Turbines throw steel shots onto workpiece surfaces at high speed.
- Rust, scale, paint, sand—all removed instantly.
- Used shots fall down and go through separation system.
- Clean shots return to storage hopper and are reused.
- Cleaned workpieces exit the machine and go to next process.
The whole process is continuous, so it is very suitable for large-volume production.
4. What Workpieces Are Suitable?
This type of blasting machine is mainly used for:
- Aluminum die-casting parts
- Iron or steel castings
- Heat-treated parts
- Automobile components
- Hardware tools
- Sheet metal parts
- Stainless steel products
- Fasteners and small-medium precision parts
Since workpieces are not tumbling, this equipment is ideal for thin, flat, or easily damaged parts.
5. Advantages of Wire Mesh Belt Shot Blasting Machine
1) Continuous Production, High Efficiency
One operator can handle whole line; production capacity is stable and high.
2) Uniform Blasting Quality
Wire mesh belt speed + multi-angle turbines ensure consistent cleaning.
3) No Damage to Workpieces
Suitable for delicate parts because no tumbling impact occurs.
4) Low Operating Cost
Abrasive is recycled automatically; turbine design is energy-efficient.
5) Easy to Connect with Automation Line
Can integrate with oven, cooling line, coating line, and robot loading.
6) Good for Mass Production
Continuous flow means very suitable for automotive and casting industries.

6. Daily Maintenance Tips (Workshop Engineer Experience)
To ensure long-term stable operation, maintenance is very important:
- Check conveyor wire mesh belt tension and wear.
- Inspect turbine blades and control cages regularly.
- Clean dust collector filter elements.
- Check abrasive amount in storage hopper.
- Ensure air separator is removing dust and broken shots properly.
- Lubricate bearings and rotating parts on time.
- Monitor chamber wear plates and replace when necessary.
Good maintenance reduces downtime and saves a lot of spare parts cost.
7. How to Choose the Right Model
When selecting a wire mesh belt blasting machine, consider:
- Size and shape of your workpieces
- Required blasting level
- Belt width (commonly 500–1500 mm)
- Number and power of turbines
- Productivity requirement (m²/h or kg/h)
- Whether you need preheating, drying, or automatic loading system
- Whether connecting to an existing production line
Choosing correct model ensures stable production, lower cost, and long equipment life.
8. Typical Industrial Applications
Wire mesh belt blasting machines are widely used in:
- Removing scale after heat treatment
- Cleaning die-cast aluminum surface
- Sand, rust, and burr removal
- Pretreatment before painting or coating
- Strengthening surface to improve fatigue resistance
It is one of the most versatile and widely used blasting machines in automotive, casting, and hardware industries.
