A PE Gold Ball Mill for chrome ore and gold mine applications is designed for efficient grinding and processing of these ores. Below are key considerations when selecting or operating a ball mill for chrome ore and gold mining:
1. Ball Mill Specifications for Chrome Ore & Gold Processing
– Type: Wet or dry grinding (wet is common for gold, dry may be used for chrome).
– Material: High-chrome steel liners & grinding media (for abrasion resistance).
– Capacity: Varies (e.g., 0.5–100 TPH depending on size).
– Speed: 70–80% of critical speed for optimal grinding.
– Feed Size: ≤25mm (may vary based on ore hardness).
– Discharge: Overflow or grate discharge (gold often uses overflow).
2. Key Features for Chrome & Gold Ores
– High Chrome Grinding Media – Resistant to wear from abrasive chrome ore.
– Gold Recovery Optimization – Fine grinding improves liberation for cyanidation/gravity separation.
– Robust Construction – Heavy-duty design for continuous mining operations.
3. Process Flow Integration
– For Gold Ores:
– Crushing → Grinding (Ball Mill) → Gravity Separation/Cyanidation → Gold Recovery.
– May include a classifier (spiral or hydrocyclone) in closed circuit.
– For Chrome Ores:
– Crushing → Grinding → Spiral Concentration/Magnetic Separation → Smelting.
4. Recommended Suppliers
– Leading manufacturers like:
– Metso Outotec

FLSmidth
– CITIC Heavy Industries
– ZJH Minerals (China-based)
5. Maintenance & Optimization Tips
– Regularly check liner and media wear (chrome ore is abrasive).
– Monitor slurry density and particle size for gold recovery efficiency.
– Use appropriate ball size (e.g., 20–100mm) based on feed size.
