For gold mining operations, a robust crushing and sand-making production line is critical to process raw ore into high-quality sand and aggregates. The typical setup includes primary crushing, secondary crushing, screening, and sand shaping stages.
1. Jaw Crusher (Primary Crushing)
– Model: JC98
– Feed Size: ≤750mm
– Capacity: 150–300 TPH
– Power: 110–160 kW
2. Cone Crusher (Secondary Crushing)
– Model: CC200
– Max Feed Size: 215mm
– Output Size: 10–40mm (adjustable)
– Capacity: 120–250 TPH
3. Vertical Shaft Impact Crusher (Sand Making)
– Model: VSI-850
– Throughput: 60–180 TPH
– Finished Sand Size: 0–5mm (95% passing rate)
Raw gold ore → Jaw crusher (coarse crushing) → Cone crusher (fine crushing) → Vibrating screen (grading) → VSI crusher (sand shaping) → Finished sand/aggregates.
Q1: What’s the lifespan of wear parts in VSI crushers?
A: Tungsten carbide tips last ~200 hours; rotor lifespan is ~1,500 hours with proper maintenance.
Q2: Can this line handle wet ore?
A: Yes, but a dewatering screen is recommended for moisture >15%.
Project: Tanzania Gold Mine (2023)
– Configuration: JC98 + CC200 + VSI-850 + 3YK3070 screen.
– Output: 200 TPH of 0–5mm sand for leaching process.
