Define the purchase decision
An iron-ore thickener procurement trial should demonstrate performance at the intended solids duty. A candidate selected on dilute laboratory feed may not support peak flux, bed inventory or underflow transport.
Keep the proposed product identity connected to the tested suspension and the intended separator.
Define normal and peak feed
Record process stage, feed solids, mineral or fines changes and flow. Keep sampling representative during source or production changes. Match dry-solids loading to the interval used for overflow and underflow observations instead of averaging across unrelated operating periods.
Use the dose calculation to compare candidates on one mass basis.
Test the balanced separation
Retain settling, overflow suspended solids or turbidity, compacted volume and shear response. Compare actual process water and an adjacent charge/molecular profile. A high-molecular-weight label is not acceptance evidence for fine capture or dense-bed behavior.
The paired endpoints keep fast settling from dominating the award.
Confirm bed and discharge behavior
At plant scale, record bed level, underflow density, rake response, pumping and throughput after meaningful residence. Avoid assigning a short-lived clear overflow to sustainable grade performance while the established bed is being consumed or diluted.
Hold settings stable for the initial product steps, then record any separately optimized operating changes.
Check a misleading apparent improvement
If peak iron-ore feed was never tested, do not scale a low-load dose and clarity result into a production-capacity guarantee. Keep the first order bounded to the demonstrated range or schedule the peak-load confirmation. Record which inventory and residence assumptions support the comparison so later results remain interpretable.
Retain the comparison conditions and any unresolved acceptance requirement with the proposed purchase.
Set the release boundary
Keep the tested flux, feed and water boundaries in the purchase record. A proposed throughput increase should remain an unverified claim until sustained operation demonstrates the corresponding solids balance.
| Purchase requirement | Required evidence | Release condition |
|---|---|---|
| Loading | Matched solids and flow record | Qualification covers the intended duty |
| Quality | Rate, overflow and compaction | Award respects multiple endpoints |
| Continuity | Bed and discharge trends | Production benefit is sustained |
