Match the grinding route to the mine
Scale, mineralogy and target liberation size decide whether a wet pan mill, ball mill or media optimization should lead the project.
Small-scale gold mining
A wet pan mill offers a compact route where capital, installed power and operator resources are limited.
Typical fit: Wet pan mill + gravity concentration
Selection checkpoints
- Crushed feed below the model limit
- Consistent water addition
- Replaceable roller and ring wear parts
Hard-rock gold processing
A ball mill provides continuous, controlled grinding ahead of gravity, flotation or leaching circuits.
Typical fit: Gold ore ball mill + classification
Selection checkpoints
- Ore hardness and required P80
- Circulating load and discharge type
- Liner and grinding media selection
Grinding media supply
Forged steel balls are matched to mill diameter, impact conditions and wear targets to control total grinding cost.
Typical fit: 20–150 mm forged steel balls
Selection checkpoints
- Current wear rate and breakage
- Hardness profile and alloy grade
- Top-up schedule and delivery volume
