Product Description
QWD1250 Mesh Belt Shot Blasting Machine
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.

Frequently Asked Questions
What is the maximum workpiece size for the QWD1250?
The machine can handle workpieces with an effective width of up to 1250 mm and a maximum height of 300 mm. The length is virtually unlimited due to the continuous mesh belt design.
What surface cleaning standard does this machine achieve?
It achieves the Sa2.5 cleaning standard according to ISO 8501-1, which is ideal for removing rust and scale before coating or painting.
Is the belt speed adjustable?
Yes, the conveyor belt speed is adjustable from 0.5 to 3 meters per minute via a Variable Frequency Drive (VFD) to suit different cleaning requirements.
How does the machine handle dust and emissions?
The system includes a high-efficiency pulse-jet baghouse dust collector. It maintains an air volume of 8000-15000 m³/h and keeps emissions below 10 mg/m³, meeting international environmental standards.
What type of maintenance is required for the blast chamber?
The blast chamber is lined with Mn13 or Cr27 high-chrome wear plates, providing a service life of over 8000 hours. Regular inspection of the blast wheels and shot level is recommended.
Can the machine be integrated into an automated line?
Absolutely. With its Siemens PLC control system and continuous flow design, it is specifically engineered to serve as a pre-treatment unit for fully automated production lines.
