China’s gold mining industry relies heavily on efficient crushing and sand-making equipment to process ore and produce high-quality aggregates for construction. Leading manufacturers supply tailored solutions, integrating jaw crushers, cone crushers, impact crushers, and sand makers into cohesive production lines.
1. Primary Crushing: Jaw Crushers (e.g., PE-600×900) with a feed size of 500mm and output of 50-160 t/h.
2. Secondary Crushing: Hydraulic Cone Crushers (e.g., HPT300) handling 200mm input, producing 30-100 t/h.
3. Tertiary Crushing/Sand Making: Vertical Shaft Impact Crushers (e.g., VSI6X1263) yielding 0-5mm sand at 200-500 t/h.
| Equipment | Model | Capacity (t/h) | Power (kW) |
|---|---|---|---|
| Jaw Crusher | PE-750×1060 | 110-320 | 110 |
| Cone Crusher | HST250 | 70-240 | 250 |
| Sand Maker | VSI5X1145 | 150-380 | 440 |
Modern lines prioritize dust suppression (water spray systems), noise reduction (<85dB), and energy efficiency (variable frequency drives). Closed-circuit designs ensure 95%+ material utilization.
Q1: What’s the lifespan of wear parts in gold ore crushing?
A1: Manganese steel jaws last ~6 months under medium hardness ore; cone crusher mantles ~4 months.
Q2: Can the same line process granite for construction aggregates?
A2: Yes, with adjustments to crusher settings and screen meshes.
