QAT5880 Hanger Shot Blasting Machine
customer feedback
“Before making our decision, we visited more than 20 shot blasting equipment manufacturers.
The QAT5880 Hanger Chian Shot Blasting Machine stood out in build quality, blasting performance, and structural detail.
After installation and commissioning, the equipment has been running steadily and delivering the expected surface preparation results. We consider it a reliable long-term investment.”
Engineered for Heavy-Duty Surface Preparation in Steel Fabrication
In heavy fabrication environments—steel structure plants, power transmission tower manufacturing, bridge construction and large equipment assembly—surface preparation is not just another process step. It directly affects coating adhesion, corrosion protection performance, and service life of the final product.
For companies handling large and heavy workpieces, consistency, throughput, and long-term reliability are decisive factors when selecting a shot blasting system.
The QAT5880 Hanger Shot Blasting Machine is engineered specifically for these production conditions. It provides continuous, high-efficiency blasting, stable quality control, and a design built for long service cycles and cost-efficient operation.
Advantages of Hanger shot blasting machines
The system is capable of handling components up to:
- 9000 × 2500 × 2500 mm
- Single piece weight up to 8,000 kg
Typical applications include:
- Heavy steel beams and structural frames
- Substation and tower components
- Wind power, shipbuilding, and industrial chassis structures
- Bridge sections and large welded fabrications
The continuous chain conveyor design allows workpieces to move steadily through the blasting zone, maintaining consistent production rhythm and uniform exposure.
High-Efficiency Blasting Core
At the heart of the machine are 16 direct-drive blast wheels (11 kW each) positioned in a staggered layout to maximize coverage.
Key features:
- High-velocity abrasive projection ensures effective rust removal and scale break-up
- Uniform blasting pattern minimizes shade zones and rework
- Low maintenance direct-drive motor structure reduces transmission loss and service downtime
- Mn13 high-manganese wear plates in hot zones deliver long in-service life (up to 20,000 hours)
This results in stable Sa2.5 surface quality (ISO 8501-1 equivalent).
Abrasive Circulation and Cost Control
The abrasive recycling and separation system is designed for clean abrasive flow and reduced consumption.
A multi-stage separation system removes dust, fines, and scale before the media re-enters the blast wheels.
Benefits:
- Less blade wear and extended service cycles
- Cleaner blasting surface finish
- Annual abrasive saving of 5–6 tons, depending on production intensity
- Lower overall operating cost per square meter of processed surface
This difference becomes significant in long-running, high-volume fabrication lines.
Environmental Performance and Dust Control
To comply with modern manufacturing and environmental expectations, the QAT5880 is equipped with a high-efficiency dust collection system:
- ≥99.5% filtration efficiency
- Emission levels ≤10 mg/m³
- Noise and dust are contained through multi-layer sealing curtains and rubber-lined chambers
This ensures a cleaner working environment and smoother downstream production such as coating or welding.
Smart Control and Maintenance Accessibility
The machine integrates an industrial PLC control system (Siemens/ABB options available), providing:
- Central monitoring
- Individual or grouped blast wheel activation
- Safety interlocks and fault diagnostics
Maintenance platforms around blast wheels allow quick and safe access for routine checks and part replacement.
