Use a clearly defined dose and price
Let d be kilograms of supplied grinding-aid product per tonne of cement and p the agreed currency units per kilogram of that product. The chemical cost is d × p, expressed in currency units per tonne of cement. It is not a recommendation for d.
If the dose is given in grams per tonne, divide by 1,000 to obtain kg/t. If it is a percentage, first confirm the numerator and denominator. The existing dosage guide owns those conversions; do not assume a clinker-based percentage is cement-based.
For a quotation per net tonne of product, divide the price by 1,000 to obtain the price per kilogram. Do not use gross package weight as chemical mass or convert a litre price using an unconfirmed density.
Illustrative calculation, not a market price
- Hypothetical inputs
- d = 0.50 kg product/t cement; p = USD 1.20/kg product.
- Chemical cost
- 0.50 × 1.20 = USD 0.60/t cement.
- Hypothetical annual quantity
- 100,000 t cement × 0.50 kg/t = 50,000 kg product.
- Annual chemical spend on this basis
- 50,000 kg × USD 1.20/kg = USD 60,000.
All inputs above are invented solely to explain the arithmetic on 9 October 2026. They are not an offer, an optimized dose or measured IN-5 performance. Tax, freight, losses, financing and other operating costs are excluded.
Round a purchasing plan to appropriate order quantities only after the packaging and supply schedule are confirmed. Do not confuse planned spend with an annual saving.
Normalize quotations before ranking them
| Field | Why the basis matters |
|---|---|
| Product and trial basis | Exact grade, net supplied mass and an evaluated dose meeting the same quality criteria. |
| Currency and date | Quote currency, validity and dated exchange-rate assumption if conversion is needed. |
| Delivery boundary | Shipment terms, destination, included freight, duties and applicable tax treatment. |
| Package and supply | Net mass, deposit or return terms, minimum order, lead time and actual usable quantity. |
| Evidence status | Confirmed trial result, supplier proposal or unverified estimate; keep these labels separate. |
If the evaluated dose is unknown, quote the unit price and mark the per-tonne calculation pending. A lower kilogram price is not enough to rank two grades with different required quantities or an unresolved performance gap.
Distinguish chemical cost from net benefit
Chemical cost is one expense line. Net benefit needs separately supported energy, material and operating changes within a defined boundary. GCP’s economic overview discusses this broader evaluation, but its historical ranges are not prices or savings for your plant.
Use the ROI calculator only with explicitly stated inputs and the relevant trial evidence. Do not count the same energy reduction twice as both a grinding-cost saving and a separate full energy benefit. Treat extra output as a scenario unless it can actually be sold and downstream constraints are addressed.
Prepare the quotation request
Send cement type, mill system, confirmed or proposed evaluation dose with its basis, target, annual cement production, required supply schedule and destination. Ask for exact grade, document availability, sample terms, net package mass, dated price, shipment terms and lead time.
For IN-5 purchase-quantity planning use its consumption guide. The dose in its supplied sheet remains a reference subject to confirmation, not a selected plant setting. This page calculates cost from agreed inputs; it cannot choose a safe dose or guarantee that a cheaper offer will meet cement-quality requirements.
Prepare your enquiry
Exact grade, confirmed dose basis, annual production, net packaging, supply schedule, destination and quote currency.
Request the exact grade, current document availability, sample terms, net package mass, quotation validity and delivery terms. Suitability and performance remain subject to applicable documents and agreed evaluation.
