Grain Milling, Dry Bulk Food & Feed Handling calculator

Energy Per Ton Calculator

Estimate energy cost per ton for milling, conveying, grinding, pelleting, mixing, or bagging using connected load, runtime, energy rate, and processed tons. Use it when operations or finance needs to compare energy intensity by mill line, product, grind size, pellet run, or conveying route.

What this calculator does

  • Estimate energy cost per ton for milling, conveying, grinding, pelleting, mixing, or bagging using connected load, runtime, energy rate, and processed tons.
  • Use it when operations or finance needs to compare energy intensity by mill line, product, grind size, pellet run, or conveying route.
  • Converts a process energy boundary into total energy cost and cost per processed ton.

Formula used

  • Energy cost = measured process load × energy measurement runtime × blended electricity rate
  • Energy cost per ton = energy cost ÷ processed dry bulk tons

Inputs explained

  • Measured process load: Use measured or connected load for mills, fans, conveyors, pellet mills, mixers, compressors, or the defined process area.
  • Energy measurement runtime: Enter hours covered by the meter reading, utility interval, production run, or cost review.
  • Blended electricity rate: Use the plant finance rate or utility tariff including demand charges if that is how energy is allocated.
  • Processed dry bulk tons: Use tons milled, conveyed, mixed, pelleted, or bagged within the same energy boundary.

How to use the result

  • Use for grind-size comparisons, fan and conveying reviews, pellet mill runs, budget updates, and quote assumptions.
  • This calculator is an estimating and planning tool. Results can change with grain type, commodity grade, test weight, bulk density, moisture percentage, temperature, fines content, particle size, screen condition, hammer or roller wear, mill gap, aspiration, dust load, bin geometry, hopper angle, angle of repose, bridging or ratholing, conveyor loading, belt speed, screw fill, bucket spacing, pneumatic conveying velocity, mixer fill level, ingredient scale accuracy, bag weight, pallet pattern, labor coverage, sanitation requirements, allergen controls, rework policy, shrink history, utility rates, and actual plant operating data. Validate food-safety, feed-safety, combustible-dust, structural, regulatory, and safety-critical decisions with qualified process, quality, maintenance, engineering, and EHS experts.

Common questions

  • What information do I need before using the Energy Per Ton? Use process load, runtime, energy rate, and tons processed from the same equipment boundary.
  • What does the result mean? The result estimates total energy cost, energy used, hourly cost, and cost per ton.
  • When is the result only an estimate? This calculator is an estimating and planning tool. Results can change with grain type, commodity grade, test weight, bulk density, moisture percentage, temperature, fines content, particle size, screen condition, hammer or roller wear, mill gap, aspiration, dust load, bin geometry, hopper angle, angle of repose, bridging or ratholing, conveyor loading, belt speed, screw fill, bucket spacing, pneumatic conveying velocity, mixer fill level, ingredient scale accuracy, bag weight, pallet pattern, labor coverage, sanitation requirements, allergen controls, rework policy, shrink history, utility rates, and actual plant operating data. Validate food-safety, feed-safety, combustible-dust, structural, regulatory, and safety-critical decisions with qualified process, quality, maintenance, engineering, and EHS experts.
  • What decision can I make from the result? Use it to compare products, justify motor or controls upgrades, update cost standards, or choose a lower-energy routing.
