Use a confirmed dose, not an assumed optimum
The supplied IN-5 document gives a reference of 0.05% on cement mass and an adjustable range of 0.04–0.06%. On that mass basis, these convert to 0.5 kg/t and 0.4–0.6 kg/t respectively. Confirm that the offered grade and supplied-liquid basis match before applying the figures to an order.
These numbers are supplier references, not a plant-specific recommendation. The model conflict in the original process section remains unresolved. This page provides purchasing arithmetic only; it does not specify dilution, process temperature or dosing equipment operation.
Collect the planning inputs
| Record | What to confirm |
|---|---|
| Confirmed dose | Dose value, unit, denominator and supplied-product basis; the person or document confirming applicability. |
| Cement production | Expected tonnes per operating hour or planned tonnes for each period. Distinguish operating hours from calendar hours. |
| Schedule | Operating hours per day and operating days in the order period. Account for planned shutdowns or different production schedules explicitly. |
| Inventory and supply | Usable opening stock, confirmed receipts, approved reserve quantity, packaging net mass and any order minimum. Do not count expired or unqualified stock as usable. |
The Dosage guide owns general unit conversions. The IN-5 trial checklist covers the evidence needed before choosing a dose.
Calculate product mass first
- Percent to kilograms per tonne
- dose (kg/t) = dose (%) × 10
- Hourly product mass
- product (kg/h) = cement output (t/h) × dose (kg/t)
- Period consumption
- product (kg) = Σ [cement tonnes in each period × confirmed dose (kg/t)]
- Planned additional purchase
- max(0, consumption + approved reserve − usable opening stock − confirmed receipts)
When production or dose changes, calculate each period separately and add the quantities. Do not multiply a peak hourly output by every hour of the month. The inventory expression is a planning convention, not a recommended reserve level.
Worked example: 20 operating days
This is an illustrative schedule, not IN-5 trial data: cement output 100 t/h, 16 operating hours/day and 20 operating days, at the supplied reference of 0.5 kg/t. Assume zero usable opening stock, no confirmed receipts and no additional reserve solely to show the arithmetic.
| Record | What to confirm |
|---|---|
| Hourly demand | 100 t/h × 0.5 kg/t = 50 kg/h |
| Daily demand | 50 kg/h × 16 h/day = 800 kg/day |
| Period demand | 800 kg/day × 20 days = 16,000 kg, or 16 tonnes of supplied product |
| Sensitivity, not optimization | At the same illustrative production, 0.4 kg/t gives 12,800 kg; 0.6 kg/t gives 19,200 kg. This arithmetic does not establish which dose is suitable. |
Use the Consumption calculator to check a confirmed scenario. Its result does not approve the input dose or the grade.
Turn the quantity into a quote request
Ask the supplier to confirm available packaging, net mass per unit, minimum quantity and delivery schedule. The supplied IN-5 record does not establish packaging availability. Round an order to confirmed pack quantities only after applying usable inventory and the agreed reserve policy.
The sheet reports a density range, but that alone does not establish a calibrated delivery volume. Request batch-relevant density and its conditions if a volume is needed; do not treat a litre calculation as a verified pump setting.
For a chemical-cost scenario, supplied-product price per kg × confirmed dose in kg/t gives product cost per tonne of cement. Freight, packaging, process effects and other costs require their own defined inputs. The ROI calculator handles a broader scenario, not guaranteed savings.
