Chat OnlineLeave Message

The core advantages of the 50tph gold ore crushing and grinding production line are controllable investment, compact process, precise grinding, high recovery rate, suitability for small and medium-sized gold mines and remote mining areas, and balance “more crushing and less grinding” with “early and fast recovery”, resulting in optimal unit cost and overall benefits.
Standard Configuration:
1. Crushing and Screening (Two-stage closed-circuit, more crushing, less grinding)
Coarse Crushing: GZD1100×4200 vibrating feeder + PE600×900 jaw crusher (processing 60–80 tph, feed ≤500mm, discharge 80–100mm)
Medium and Fine Crushing: HST160 (processing 50–60 tph, discharge 10–20mm)
Closed-circuit Screening: 2160 double-layer vibrating screen (oversize >20mm returned, undersize 10–20mm fed into mill)
Iron Removal: Permanent magnet separator after coarse crushing to protect the cone crusher and mill
2. Grinding and Classification (Closed-circuit precise liberation)
Grinding: Φ1830×3000 ball mill (processing 50 tph, grinding to -200 mesh) (80%–85%) Classification: FG20 spiral classifier / Φ350 hydrocyclone (coarse particles return to the mill, fine slurry enters the separator)
The entire production line consumes 14–18 kWh/t of electricity. It is a hybrid of diesel and photovoltaic power, which reduces energy consumption by 12%+ per unit. It is also a high-temperature resistant, wear-resistant, and easy-to-maintain model, which is very suitable for the working conditions in West Africa.
