In gold mining, crushing is the first critical step to liberate gold particles from ore. A well-designed crusher and sand-making production line ensures efficient processing, high recovery rates, and optimal particle size for downstream processes like grinding and leaching.
1. Jaw Crusher (Primary Crushing)
– Processes large ore chunks (≤1,200mm) into smaller pieces (≤350mm).
– Key parameters: Feed opening 1,200×1,500mm, Capacity 400–800 t/h.
2. Cone Crusher (Secondary/Tertiary Crushing)
– Further reduces ore to ≤50mm for finer grinding.
– Key parameters: Power 160–400 kW, Closed-side setting 10–50mm.
3. Vertical Shaft Impact Crusher (Sand Making)
– Produces cubical sand (0–5mm) for heap leaching or tailings reprocessing.
– Key parameters: Rotor speed 1,500–2,000 rpm, Throughput 100–600 t/h.
Ore → Vibrating Grizzly Feeder → Jaw Crusher → Cone Crusher → VSI Crusher → Screening → Grinding/Leaching. Closed-circuit systems with screens improve efficiency by recycling oversized material.
