Product Overview

The QWD1250 Mesh Belt Shot Blasting Machine is a continuous surface treatment system engineered for small-to-medium batch components in foundry, forging, machining, and sheet metal industries. It effectively removes scale, sand adhesion, burrs, rust, and old coatings while enhancing surface finish and profile. Featuring a fully enclosed stainless steel mesh belt conveyor and multi-angle high-efficiency blast wheels, it handles workpieces up to 1250 mm wide with unlimited length. It achieves cleaning standard Sa2.5 (ISO 8501-1)—an ideal pre-treatment unit for automated production lines.

Key Technical Features

1

Wide Mesh Belt – Versatile Handling Effective width: 1250 mm; belt speed: 0.5–3 m/min (VFD adjustable). Handles parts up to 300 mm tall—supports stacked or single-layer loading.
2

Multi-Wheel 360° Coverage Equipped with 4–8 high-efficiency blast wheels (7.5–15 kW each), arranged for full coverage of complex geometries including cavities, grooves, and welds.
3

Closed-Loop Recycling Integrated 3-stage shot separation ensures ≥99% shot purity. Paired with pulse-jet baghouse—emissions ≤10 mg/m³, compliant with international regulations.
4

Smart Control System Siemens PLC + 10" HMI stores recipes, logs faults, and tracks energy use. Includes full safety interlocks and overload protection.

Frequently Asked Questions

What is the maximum size of workpieces the QWD1250 can handle?

The machine features an effective width of 1250 mm and can accommodate workpieces with a maximum height of 300 mm. The length is virtually unlimited due to the continuous mesh belt design.

How is the cleaning quality ensured for complex shapes?

The system utilizes 4 to 8 high-efficiency blast wheels positioned at multiple angles (top, bottom, and sides). This ensures 360° coverage, reaching into cavities and grooves without blind spots.

Can the conveyor speed be adjusted for different materials?

Yes, the stainless steel mesh belt speed is adjustable from 0.5 to 3 meters per minute via a Variable Frequency Drive (VFD), allowing you to customize the intensity based on the workpiece material and surface condition.

What kind of maintenance is required for the wear plates?

The blast chamber is lined with Mn13 or Cr27 high-chrome wear plates, which are designed for high durability with a service life of over 8,000 hours under standard operating conditions.

Is the machine environmentally compliant?

Absolutely. It includes a pulse-jet baghouse dust collector with an air volume of 8000-15000 m³/h, maintaining emissions at ≤10 mg/m³, which meets stringent EU and international environmental regulations.

What control system does the machine use?

The machine is equipped with a Siemens PLC and a 10-inch HMI touch screen. It supports recipe storage, fault logging, energy tracking, and is capable of remote monitoring.
