Product Description

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.
