**Application:**
This series of machines belongs to the roller-type shot blasting machine, primarily used for stress relief and surface rust removal of steel structures such as large H-beams in construction and bridge industries.
**Advantages:**
1. **Conveying System:** The total length is approximately 28 meters, with high synchronization requirements. Each roller is driven by a frequency conversion motor, and the loading capacity is 1.0 T/meter.
2. **Inlet and Outlet Rollers:** These are welded using high-quality carbon steel seamless steel tubes and conditioning shaft heads. After welding, the appearance and installation size are processed to ensure a loading capacity of 1.0 T/meter and proper alignment.
3. **Blast Wheel System:** The blast wheel system is optimized through computer simulation. A total of 8 blast wheels cover both top and bottom surfaces, ensuring even and effective blasting.
4. **Blast Angle:** The correct angle between the blast wheel and the workpiece ensures optimal blasting performance and prevents shot accumulation on curved surfaces, which could affect cleaning efficiency.
**Parameters:**
| Model | Size of Piece | Speed of Roller (m/min) |
|---------|------------------------|--------------------------|
| QH698 | 800*1200–1200*1800 | 1–5 |
| QH6912 | 1200*1800–1500*2000 | 1–5 |
