Mesh Belt Shot Blasting Machine

Mesh Belt Shot Blasting Machine – Automated Flat‑Conveying Solution for Thin‑Wall and Precision Components for Precision Surface Treatment

Mesh Belt shot blasting machine is an industrial‑grade system offered by Botou Junda Machinery Equipment Co., Ltd., specially designed for high‑volume, non‑tumbling surface treatment of fragile workpieces. Drawing on more than 20 years of casting‑machinery expertise and a 3,000 m² production facility, our equipment incorporates a 304 stainless‑steel mesh conveyor, double‑sided blasting configuration and VFD‑controlled speed ranging from 0.5‑3 m/min. Featuring a compact design with a 300 mm low‑clearance passage optimized for thin sheets and precision stampings, four strategically positioned turbines deliver simultaneous cleaning for top and bottom surfaces. Standard configurations support conveyor widths of 600‑1500 mm with custom expansion available, delivering high throughput for die‑casting, stamping and metallurgical processing lines.

What Makes Our Mesh Belt Shot Blasting Machine Stand Out

Unlike traditional tumble or roller systems, this shot blaster transports workpieces horizontally on a flat stainless‑steel mesh belt. It prevents impact‑caused damage to thin‑wall castings, aluminum‑alloy parts and precision stamped components.

Grade‑304 woven belt resists corrosion and eliminates secondary rust contamination. Your aluminum and zinc parts remain rust‑free and clean during blasting operations.

Four blast turbines are mounted in a double‑sided layout: two turbines target the top surface while the other two target the bottom surface. Uniform cleaning is achieved on both sides in one pass, doubling your production efficiency.

The maximum passage height is limited to 300 mm, making the chamber ideal for flat plates, gears and thin‑wall die castings. Compared with roller pass‑through models, this low‑profile design eliminates wasted vertical space and reduces machine footprint.

Technical Specifications

Core Performance Advantages

Your thin aluminum sheets and precision stampings translate on the mesh belt without scratches or deformation. Delicate geometries stay intact throughout the blasting cycle.

Variable‑frequency drive technology adjusts conveying speed according to workpiece thickness. Low speed avoids sheet penetration for thin plates, while higher speed boosts throughput for thicker components.

Fully enclosed abrasive recovery troughs sit underneath the mesh belt to capture abrasive media before it escapes. This design cuts steel shot leakage and substantially reduces consumable costs.

Compact machine length fits well within small‑to‑medium automated production lines. You get efficient cleaning performance without the large footprint required by roller‑conveyor systems.

Custom belt width and extended‑chamber options allow you to scale hourly processing capacity according to production demands. Configurations adapt to your workflow whether you process small fasteners or large flat panels.

Industrial Applications

Automotive die‑casting plants rely on the Mesh Belt Shot Blasting Machine to process thin‑wall engine covers and gearbox housings. The flat‑conveying method prevents dimensional warpage caused by conventional tumbling systems.

Steel‑structure manufacturers use this equipment for continuous descaling of small‑and‑medium steel plates. Consistent surface profiles prepare flat weldments for powder coating or galvanizing with no manual intervention.

Consumer‑hardware manufacturers achieve uniform appearance for hand tools and building components. High‑volume processing maintains quality standards while lowering labour costs compared with manual blasting.

Metallurgical and chemical processing plants integrate these systems into automated surface‑treatment production lines. The rust‑proof stainless‑steel mesh withstands corrosive environments without contaminating workpieces.

Frequently Asked Questions

Q: What are the maximum passing width and height for workpieces?

A: The standard effective mesh width reaches 1000 mm and maximum workpiece height is 300 mm. Its load‑bearing capacity supports flat plates and gears up to 150 kg per square meter.

Q: Is this machine suitable for aluminum and zinc‑alloy castings?

A: Fully compatible. The stainless‑steel mesh avoids rust contamination. Use stainless‑steel shot for aluminum workpieces to achieve bright surface finishes without dark discoloration.

Q: Can both sides be cleaned in one single pass?

​​​​​​​ A: Four blast turbines are installed for simultaneous top‑side and bottom‑side blasting. Secondary flipping of workpieces is not required.

Q: Is the stainless‑steel mesh fragile with high replacement costs?

A: Heavy‑duty woven stainless‑steel mesh can last more than one year under normal operation. Standard spare‑part replacement is simple with low maintenance costs.

Q: How to prevent small parts from falling through mesh gaps?

A: We offer customizable mesh density and tighter woven patterns. Transverse guide rails secure even the smallest fasteners during transportation.
