A glass manufacturing company needed to recycle broken glass by crushing it into glass sand and grading it into multiple particle sizes. These graded materials are used for different glass products and production lines.
To meet strict production requirements, the customer required precise screening at the following mesh sizes:
8 mesh, 10 mesh, 18 mesh, 35 mesh, and 90 mesh
Crushed glass sand poses several difficulties:
Wide particle size range requiring accurate multi-stage screening
High hardness and abrasiveness, causing fast equipment wear
Fine powder content, leading to mesh blockage
Irregular particle shape, lowering flowability
Dust pollution risk during the screening process
The customer needed a screening solution capable of:
Five-level separation in a single machine
High screening accuracy with minimal cross-contamination
24/7 continuous operation
Strong wear resistance and long equipment lifespan
Dust-free operation for a cleaner working environment
Reduced downtime and easier maintenance
After site evaluation and testing, we recommended a five-layer square gyratory screen, configured specifically for glass sand properties.
• Multi-layer structure: 8/10/18/35/90 mesh
• Thickened, wear-resistant frames
• Three-dimensional elliptical tumbling motion
• Anti-blocking system with bouncing balls
• Fully sealed design to prevent dust leakage
• Heavy-duty construction for long-term operation
The customer achieved outstanding results after installing the square tumbler screen:
| Mesh Size | Result | Accuracy | Notes |
|---|---|---|---|
| 8 mesh | Clean coarse grade | ≥96% | Ideal for remelting |
| 10 mesh | Stable medium particles | ≥95% | Good shape retention |
| 18 mesh | High yield | ≥95% | Smooth and consistent |
| 35 mesh | No mesh blockage | ≥93% | Fine material well separated |
| 90 mesh | Stable ultrafine grade | ≥92% | Excellent dust control |
Overall Improvements
Output increased by 35–50%
Cross-contamination reduced to 3–5%
Zero dust leakage, cleaner workshop
Continuous operation with minimal maintenance.
“The square gyratory sifter delivers highly accurate multi-stage separation. Even at 35 and 90 mesh, we no longer face mesh blockage or contamination issues.
The machine is stable, low-maintenance, and perfect for glass sand processing.”
