Two Blast Wheels Tumble Drum Shot Blasting Machine 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.

• 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).

• 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.

• Castings: Iron/steel castings (valves, pumps, fittings, small machinery housings).
• Forgings: Small-to-medium forgings (gears, shafts, brackets, connecting rods).
• Stampings & Fabrications: Sheet metal parts, welded assemblies, brackets, chassis components.
• Heat-Treated Parts: Springs, fasteners, bearings, and components requiring post-heat treatment cleaning/strengthening.
• Non-Ferrous Parts: Aluminum, brass, and copper castings/stampings (gentle tumbling).
