Sand mining for zircon extraction faces significant challenges, including environmental concerns and inefficient processing. To address these issues, modern crushing and sand-making production lines are designed with high efficiency and sustainability in mind.
A complete production line typically includes:
1. Primary Jaw Crusher (PE-600×900)
– Capacity: 50-160 t/h
– Motor Power: 55-75 kW
2. Secondary Cone Crusher (HPT300)
– Max Feed Size: 240mm
– Capacity: 120-400 t/h
3. Vertical Shaft Impact Crusher (VSI6X1263)
– Throughput: 200-500 t/h
– Rotor Speed: 1700-1900 rpm
4. High-frequency Screen (YKN2460)
– Screening Area: 9.6m²
– Mesh Size: 0.074-50mm
| Equipment | Feed Size | Output Size | Capacity |
|---|---|---|---|
| Jaw Crusher | ≤500mm | 60-140mm | 50-160t/h |
| Cone Crusher | ≤240mm | 10-45mm | 120-400t/h |
| VSI Crusher | ≤50mm | 0-5mm adjustable | 200-500t/h |
Q1: How to reduce over-crushing of zircon particles?
A: Adjust VSI rotor speed and optimize screen mesh sizes.
Q2: What’s the typical zircon recovery rate?
A: Modern lines achieve 85-92% recovery with proper configuration.
Q3: How to handle clay contamination?
A: Add a log washer or attrition scrubber before crushing.
