Cost of a wrong decision

How energy consumption changes feed mill economics

Short answer

Energy is the operating cost most often left out of a CAPEX comparison and the one that compounds fastest. Grinding, pelleting or extrusion and drying dominate consumption; conveying, aspiration and cooling add a steady base load. A difference of a few kWh per tonne, multiplied by annual tonnage and your tariff, produces an annual cost that can exceed the CAPEX difference between two proposals within a few years. Require expected kWh per tonne for the quoted configuration, state your tariff and annual tonnage, and model the energy cost alongside CAPEX before ranking offers.

Energy is where a cheaper plant quietly becomes the expensive one — especially in markets with high tariffs or unreliable grids requiring backup generation.

Where the energy goes

Grinding: strongly dependent on screen size, formulation and mill type
Pelleting: die specification, conditioning quality and pellet diameter
Extrusion and drying: the dominant load in aqua feed plants
Cooling, aspiration and dust control: continuous base load
Conveying and elevators: layout-driven, often underestimated
Compressed air and boiler auxiliaries

Modelling it

Ask for kWh per tonne for the quoted configuration and the assumed recipe
Multiply by annual tonnage and your delivered tariff, including demand charges
Add generator fuel cost where grid reliability requires backup running hours
Compare annual energy cost differences against the CAPEX difference
Recheck at the growth tonnage, not only at year-one volume

Questions buyers ask

Is a lower kWh per tonne always worth a higher CAPEX?

Only when the difference, multiplied by realistic annual tonnage and your tariff, pays back within a horizon your business accepts. Model it explicitly; the answer varies enormously between a 3 t/h mill on cheap power and a 30 t/h mill on expensive power.

Do suppliers guarantee energy consumption?

Some will state expected consumption for a named configuration and recipe; guarantees are less common than throughput guarantees. Ask, and record whatever is provided in writing.
