Wire mesh belt shot blasting machine is a type of continuous blasting equipment used for cleaning, descaling, deburring, and surface strengthening of metal parts. It uses a durable wire mesh conveyor belt to carry workpieces through a blasting chamber, where high-speed steel shots are thrown by blasting turbines to clean the surfaces.
Main Function of Wire Mesh Belt Shot Blasting Machine
The wire mesh belt shot blasting machine is a very important surface treatment equipment widely used in foundry, forging, heat-treatment workshop and metal fabrication industry. In daily production, this machine helps us to carry out continuous and efficient blasting work, making the parts achieve clean surface and stable quality.
1. Continuous and Uniform Shot Blasting
Because the machine uses a strong wire mesh belt conveyor, the workpieces can move forward steadily under the blasting chamber. The blasting turbines throw high-speed steel shots to all directions, achieving even cleaning on the whole surface. This continuous type design makes the productivity much higher than single-piece blasting machines.
2. Rust Removal and Oxide Scale Cleaning
In heat treatment and metal processing, workpieces usually have heavy oxide scale or rust. The wire mesh belt machine can remove these layers efficiently, bringing out fresh metal surface. This function is especially important for parts before painting, coating, or further machining.
3. Surface Strengthening (Shot Peening Effect)
During the blasting process, steel shots hit the surface repeatedly, producing a certain peening effect. It improves fatigue strength and makes the surface structure more compact. Many forged parts and automotive components require this strengthening process to improve service life.
4. Improve Surface Roughness for Better Coating Adhesion
After shot blasting, the surface becomes clean with proper roughness. This roughness helps the paint, powder coating or other protective layers to adhere more strongly. In coating lines, the wire mesh belt shot blasting machine is usually installed as the front pre-treatment equipment.
5. Suitable for Various Workpiece Shapes
The wire mesh belt allows many small or medium-size parts to be loaded in batches. Whether flat plates, castings, stampings, or welded assemblies, they can pass through the blasting zone without complicated fixturing. The belt can also prevent workpieces from sticking together because the vibration is small and the transport is stable.
6. Continuous Production and High Efficiency
This machine is designed for mass production. Operators only need to place workpieces at the inlet, and the cleaned parts will automatically come out at the outlet. It reduces labor intensity and is very suitable for automation lines.
7. Reduce Manual Grinding and Improve Product Consistency
Compared with manual grinding or pickling, shot blasting produces more uniform results. It also reduces environmental pollution, meeting green manufacturing requirements. For factories requiring stable batch quality, this machine is a key equipment.
Wire Mesh Belt Shot Blasting Machine – FAQ
1. What types of parts can be processed?
It is suitable for small and medium-size components, especially:
- Iron and steel castings
- Aluminum die-cast parts
- Heat-treated parts
- Stamping parts
- Forgings
- Flat plates, sheets, profiles
- Hardware parts and welded assemblies
As long as the parts can sit steadily on the mesh belt, they can be processed.
2. How does the machine work?
- Load parts on the inlet section.
- Wire mesh belt conveys the parts into the blasting chamber.
- Blast turbines throw steel shots uniformly from top and bottom.
- Surface contaminants are removed.
- Clean parts exit automatically at the outlet.
- Steel shots are recycled, screened, and reused.
3. What is the advantage of using a wire mesh belt?
- Stable conveying and lower collision between parts
- Good air flow and abrasive flow through the belt
- Suitable for various part sizes and shapes
- Supports continuous and automated production
- Does not require special fixtures for most workpieces
4. What blasting media can be used?
Normally:
- Steel shot
- Steel grit
- Stainless steel shot (for aluminum or stainless parts)
The selection depends on material hardness and required surface roughness.
5. What is the typical blasting speed?
Usually between 0.5–5.0 m/min, depending on:
- Cleanliness requirement
- Number and power of blast wheels
- Workpiece thickness and contamination level
- Type and size of abrasive
6. How long does the wire mesh belt last?
This depends on usage, but typically 18 months.
Correct tensioning and avoiding sharp edges on workpieces can extend the life.
