Two blast wheels tumble drum type shot blasting machine Q3220 with rubber belt apron for batch cleaning
Q3220 is a heavy-duty, medium-to-large crawler-type tumble blasting machine designed for high-volume surface treatment of small-to-medium metal parts. It features dual high-power blast wheels, large loading capacity, and high productivity, suitable for batch cleaning and strengthening.
1. Core Capabilities
Cleaning & Strengthening Functions
- Descaling & Rust Removal: Removes oxide scale, rust, sand, and other surface contaminants from castings, forgings, stampings, and heat-treated parts.
- Surface Strengthening: Improves fatigue resistance and mechanical properties by inducing compressive stress on metal surfaces.
- Deburring: Removes burrs and flash from machined/stamped parts (gentle tumbling action).
Key Performance Advantages
- Dual Blast Wheels: Two high-efficiency impellers deliver uniform, high-intensity blasting coverage.
- Continuous Tumbling: Rubber/metal crawler belt gently rotates workpieces for 360° exposure to shot stream.
- High Productivity: Up to 5–6 tons/hour cleaning capacity for medium parts.
- Automation Ready: Supports automatic loading/unloading; can integrate into production lines.
- Durable Construction: Wear-resistant liners in blast chamber; robust crawler belt for heavy loads.
- Efficient Dust Collection: Equipped with high-capacity pulse-jet baghouse for clean operation.
