Application guide / generalized scenario
For this Chile copper-oxide scenario, compare feed uniformity and dust-control constraints alongside peak TPH. This guide outlines three routes for validation.

01 / Reference conditions
Assume fines generation can trade off against leach permeability. Validate the crusher setting against a shared particle-size and permeability envelope before selecting the route.
This note is for teams choosing between low-complexity, balanced, and high-control layouts in the 150-320 TPH class.
02 / Selection logic
01
Condition
Leach pad performance is sensitive to fines generation
Recommendation
Keep reduction work primarily in cone stage with conservative settings
Operating reason
It is easier to protect permeability when breakage is controlled and predictable.
02
Condition
Site has strict dust permit and limited water for suppression
Recommendation
Prioritize enclosed transfer points and stable recirculation load
Operating reason
Unstable recirculation increases transfer dust and operating interruptions.
03
Condition
Mine blend swings between soft oxidized zones and harder transition ore
Recommendation
Use route with clear tuning envelope and disciplined blending
Operating reason
If blend variability is the cause, controlling the blend should be tested before adding another machine.

05 / Comparison matrix
Swipe or scroll horizontally to compare all three routes.
| Metric | Lean | Balanced | High-control |
|---|---|---|---|
| Planning condition | Stable oxide feed | Mixed oxide-transition feed | Highly variable blend with strict leach KPIs |
| Fines control | Basic | Good | High (validate) |
| Operational burden | Low | Medium | Medium-high |
| Main risk | PSD drift on blend changes | Screen bottleneck if maintenance slips | Over-capitalization for short mine life |
| Relative equipment scope | Lower | Medium | Higher |
06 / Operating context
Crusher selection should be reviewed together with leach operations. Without a shared PSD envelope, tuning decisions cannot be checked against one acceptance basis.
The simplest way to prevent this is a one-page acceptance sheet: feed window, fines cap, permeability target, and response plan when blend drifts.
Ask each vendor for throughput at three ore scenarios: soft oxide, mixed feed, and harder transition ore. One-point capacity claims are not decision-grade data.
Normalizing proposals on the same ore assumptions makes commercial differences easier to compare and variation-order causes easier to trace.
