Confirm that the instructions belong to IN-5
The IN-5 product page identifies the supplied brown liquid compound grinding aid. The original document also contains a process section labelled TGA-5 and differing cement designations. These are unresolved applicability questions, not permission to transfer that section to IN-5.
Before operational use, obtain a current IN-5-specific TDS and SDS, confirmation of intended cement types and written clarification of the conflicting references. This page does not supply dilution, temperature, commissioning or safe-handling instructions.
Define the decision and evidence needed
Choose a primary trial question: a change in output at comparable quality, a change in specific energy at comparable output and quality, or a cement performance target. Keep the quality limits explicit. The General mill protocol owns the broader trial method; this supporting page adds the IN-5 identity and evidence checks.
| Record | What to confirm |
|---|---|
| Grade and batch | IN-5 identification, supplier, current revision, sample or delivery batch and available COA. Ask which reported properties are batch-tested. |
| Dose confirmation | The supplied reference is 0.05% on cement mass, with 0.04–0.06% also mentioned. Confirm applicability and supplied-liquid basis with the supplier; the range is not an optimized setting for your mill. |
| Cement and circuit | Cement designation and composition, clinker and addition sources, mill type, circuit configuration and the responsible technical team. |
| Goal and acceptance criteria | Define the output or energy question, fineness and quality targets, sampling plan and review responsibility before comparing results. |
Do not infer that IN-5 is neat TEA, TIPA or DEIPA, or that a generic chemical-family description supplies its formulation.
Build a baseline that can be compared
| Record | What to confirm |
|---|---|
| Feed and operating conditions | Record cement composition, material batches and relevant operating conditions over matched reporting windows. Log changes rather than treating them as unchanged. |
| Output and energy boundary | Record actual cement output, metered energy and the equipment included in the boundary. Use compatible time windows and state the basis for kWh/t. |
| Quality | Record fineness and relevant particle-size, setting and strength results using the plant’s agreed methods and ages. Retain sample IDs and test conditions. |
| Additive delivery | Record the confirmed product basis and actual product mass consumed against cement output. Retain the dosing system’s applicable verification record; nominal settings alone do not establish delivered mass. |
If feed composition, separator settings or quality targets change at the same time as the additive, report those changes. Do not label the entire difference an IN-5 effect. The Troubleshooting centre helps organize observations that need investigation.
Review the data in stages
- Check model and document applicability before treating a dose or process note as usable.
- Compare matched baseline and candidate windows and identify process deviations.
- Associate the corresponding cement samples with their laboratory results.
- Review quality alongside output and energy; a larger output number alone is not acceptance.
- Record repeat-evaluation needs and the responsible team’s decision before commercial scale-up.
Chryso’s published limestone-cement case identifies the mill circuit, cement changes, samples and performance review. It is an example of trial documentation, not evidence of an IN-5 result. Documented mill case.
Keep a technical result separate from an ROI estimate
Use actual delivered product mass and the offered price to estimate chemical cost. State whether an energy comparison uses the same quality target and system boundary. Any output benefit needs a defined commercial assumption; do not count it automatically as realized revenue.
ROI calculator can organize scenario arithmetic after the trial assumptions are established. IN-5 purchase planning converts a confirmed dose and production schedule into quantities.
GCP’s HEA2 page discusses product-specific dosing equipment and evaluation support, and restricts its information to Thailand. Its dose and dilution instructions do not apply to IN-5. External-grade reference.
Send the IN-5 evaluation brief
Include cement designation and composition, mill system, production and energy baseline, quality targets, sampling capability, proposed evaluation window and the document conflicts you need clarified. Request the current IN-5 specification, SDS and sample traceability.

No IN-5 plant trial, energy saving, strength uplift or compliance approval is verified by this checklist. Site-specific procedures remain with the responsible technical and safety teams.
