Comminution Specific Energy Calculator
Audit actual energy meter/dry-throughput ledger with independent auxiliary exclusions, not forward Bond required energy or nominal power×production. Caller independently verifies units, applicability and matching conditions; no operational recipe, safety certification, causal efficacy or legal/resource classification is inferred.
Description
Comminution specific energy relates measured energy to matched dry throughput.
Comminution specific energy relates measured energy to matched dry throughput.1
Independently measured auxiliary exclusions distinguish gross from net energy.
When to use Comminution Specific Energy Calculator
Use this tool to calculate or review the supplied observations under the stated rules. Match completed survey or ledger observations by block, segment or stage and confirm their units and boundaries.
How to use Comminution Specific Energy Calculator and understand its results
- Match completed survey or ledger observations by block, segment or stage and confirm their units and boundaries.
- Enter observedMillEnergyKwh, observedNonComminutionEnergyKwh, observedProcessedDryTonnes, using the field meanings and rules below, then run the tool.
- Read observedGrossSpecificKwhT, observedNetSpecificKwhT. Inspect nested result fields where present, and review unknown records separately from known matches.
- Correct any reported input issue and run again. Before using a successful result, check the stated units, signs, reference scope and observation coverage.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| observedMillEnergyKwh | Observed mill energy kwh | list of number | Required |
| observedNonComminutionEnergyKwh | Observed non comminution energy kwh | list of number | Required |
| observedProcessedDryTonnes | Observed processed dry tonnes | list of number | Required |
Use aligned throughput>0 dry tonnes and nonnegative gross and excluded energy. Each excluded energy must be≤gross. Return total gross/total tonnes and (total gross−total exclusions)/total tonnes in kWh/t.
grossSpecific=Σgross/Σtonnes; netSpecific=Σ(gross−excluded)/Σtonnes Use the matching field units and the exact boundary, ordering and reference rules above.
| Output field | Meaning | Value type |
|---|---|---|
| observedGrossSpecificKwhT | Observed gross specific kwh t | number |
| observedNetSpecificKwhT | Observed net specific kwh t | number |

}Limitations and assumptions
Units, ledger boundaries, survey interpretation and model applicability must be independently established. These summaries do not assign reserve/resource classifications or establish support adequacy, ventilation safety or an operating setting.
Missing required fields, unknown fields, wrong types and violated rules return input issues. Numeric values and outputs must be finite. Lists and matrices must be dense, without missing cells. Numeric lists allow at most 10000 entries; ordinary string lists allow at most 128 strings of 128 UTF-16 units each; numeric matrices allow at most 128 rows and 128 columns, subject to narrower requirements above.
Alternative or Complementary methods
For a related step, use Bond Operating Work Index Calculator: An operating Bond index can be inferred from net observed energy and matched size reduction. For a complementary comparison, use Electrowinning Power Consumption Calculator: Metered electrowinning energy can include separately measured auxiliary consumption.
