Wet-grinding quotation / Rate audit
A quoted kg/h can describe fresh material entering a single-pass route, product circulating repeatedly through a batch loop, material leaving the mill, accepted output at a stated endpoint, or production averaged across a batch, shift or campaign. The number is not comparable until its material boundary, flow path, clock, endpoint and yield treatment are named.
Stop the headline comparison
This page audits the commercial production-rate claim. It does not choose single-pass or recirculation operation, calculate residence time, normalize specific energy, set a particle endpoint or provide a scale-up factor.
Ask whether the field is pump or loop flow, fresh feed into one pass, gross outlet from the mill, accepted product after the agreed endpoint, or output across a complete batch, shift or campaign. A recirculating quantity can cross the mill many times without becoming new accepted output.
Attach formulation and feed state, route, sample identity, endpoint method and disposition. Product that has merely moved through the mill is not automatically accepted yield, and a named fineness or distribution remains governed by its own method record.
Declare whether the clock includes charging, line priming, ramp-up, sampling, laboratory waiting, planned holds, interruptions, drain and recovery, cleaning and changeover. Reconcile samples, retained heel, off-spec, rework and cleaning loss before calling gross movement production yield.

| Audit row | Proposal A | Proposal B | Release record |
|---|---|---|---|
| Original rate label and unit | Copy the source value, unit, label, document revision and nearby notes without renaming flow as throughput or capacity. | Preserve the second source in the same way; keep volume per time and mass per time distinct unless a controlled density basis and state are supplied. | Original quotation fields, unit definitions, material state, density source if a conversion is proposed, data owner and unresolved ambiguity. |
| Material path and rate identity | Mark pump or loop circulation, fresh single-pass feed, mill discharge, accepted downstream output, batch average, shift average or campaign average. | Map the second proposal independently; do not treat repeated loop crossings as newly produced material or assume an outlet field is accepted product. | Process-flow sketch, tank and mill boundaries, return path, transfer points, measurement location and one approved name for every rate field. |
| Feed, configuration and operating mode | Attach product and lot, composition, solids or concentration basis, rheology, temperature, feed state, mill, media, separator and pass or loop history. | Record the same fields for the second proposal and disclose every difference instead of importing a rate from another material or configuration. | Configuration-controlled test record and the separate operating-mode decision that applies to the quoted rate. |
| Endpoint and accepted disposition | State sample point and time, preparation, test method, instrument or gauge basis, acceptance rule and whether the quantity passed, waited, reworked or was rejected. | Use the same endpoint and disposition vocabulary or show why its output cannot be compared directly. | Matched release method, identified samples, result record, accepted quantity, rework or rejection quantity and responsible approver. |
| Elapsed-time boundary | Define clock start and stop, then list charging, priming, ramp-up, milling, sampling, holds, downtime, drain, cleaning and changeover as included or excluded. | Apply the same time ledger to the second proposal; do not compare a run-only rate with a shift or campaign average without preserving both records. | Time-stamped event log, included productive interval, excluded interval with reason, planned operating window and comparison basis. |
| Material balance and accepted yield | Record charged material, additions, samples, retained hold-up or heel, normal recovery, gross discharge, off-spec, rework, cleaning loss and accepted output. | Reconcile the second proposal with the same categories; do not infer accepted yield from pump flow or gross discharge alone. | Quantity source and uncertainty for every balance row, accepted disposition, unexplained difference and owner for closure. |
| Production window and confirmation | Identify whether the claim belongs to a test interval, one batch, repeated batches, a shift or a campaign, plus staffing, upstream and downstream constraints. | Identify its window and constraints separately; keep model- or application-specific source results attached to their original evidence. | Representative confirmation plan, supplier review, uptime and changeover assumptions, acceptance owner, exclusions and change triggers. |
Audit route
Preserve the quoted number first, then rebuild its material path, production clock, endpoint and material balance before comparing proposals or planning a representative confirmation run.
Retain the quote, value, unit, label, footnote, product, configuration, test or application context, author and revision.
Locate the measurement in the flow path and create an included-versus-excluded ledger from loading through changeover.
Separate gross movement from accepted product using traceable samples, disposition and a complete material balance.
Agree a representative batch, shift or campaign plan with the candidate supplier and responsible process, laboratory and production reviewers.

Draft source record / Pending technical review
These current first-party sources were checked on 31 July 2026. They use flow rate, throughput capacity, working capacity, running time and product-path language on named machines or applications, with material, endpoint, configuration or route conditions attached. Their values, models, features and results are excluded.
Buyer decision FAQ
Not automatically. A flow value may describe pump delivery, mill inlet or outlet flow, or repeated circulation through a loop. Production throughput may instead mean fresh feed, accepted outlet, batch average, shift average or campaign output. Identify the material path, quantity basis, clock and endpoint before comparing them.
No. The same material can cross the mill repeatedly in a recirculation route. Record loop flow separately from fresh additions, gross discharge and accepted product. The operating-mode guide owns the route decision; this page owns the commercial meaning of the rate field.
No. Accepted yield needs a defined endpoint and disposition plus a material balance covering charge, additions, samples, hold-up, recovery, off-spec, rework, cleaning loss and unexplained difference. Gross movement alone does not establish accepted product.
The quote must declare the clock boundary. Preserve a run-only rate separately from a batch, shift or campaign average, then state whether charging, sampling, holds, downtime, draining, cleaning and changeover are included or excluded.
Not without matching the material and feed state, mass or volume basis, operating route, configuration, endpoint, elapsed-time boundary, recovery and production window. Any difference remains visible and requires supplier and technical review.
No. It publishes an audit structure only. JINPIONEER model, configuration, flow, throughput, yield, endpoint, production result and guarantee remain unconfirmed until supported by supplier engineering and representative evidence for the project.
