removal radioactivity from zircon sand

Zircon Sand Processing Line for Radioactivity Reduction

Zircon sand, a valuable mineral resource, often contains natural radioactivity (U/Th). Specialized crushing and grinding equipment is required to reduce radiation levels while preserving zircon’s industrial properties.

Key Equipment for Zircon Processing

The complete production line includes:
1. Jaw Crusher (PE-600×900) – Primary crushing
• Feed size: ≤500mm
• Capacity: 50-160t/h
2. Cone Crusher (HPT-300) – Secondary crushing
• Closed-side setting: 19-38mm
• Throughput: 120-250t/h
3. High-Gradient Magnetic Separator (XCRS-400)
• Magnetic intensity: 1.0-1.8T
• U/Th removal rate: ≥85%

Process Flow

Raw zircon sand → Primary crushing → Screening → Secondary crushing → Magnetic separation → Radiation testing → Finished product storage. The two-stage magnetic separation system ensures effective radioactive element removal.
