Where the power goes

The big consumers

Roller mills: the largest share. Each roller mill motor is 5.5–37 kW depending on roll length.
Pneumatic conveying and dust control: high-pressure fans of 2.2–45 kW lift stock between floors.
Cleaning: scourers of 4–22 kW, plus separators, destoners and aspiration.
Sifting and purifying: plansifters of 3–5.5 kW each; purifiers under 1 kW.
Packing: about 2.2 kW per packing scale, plus compressed air.

Questions

Power questions buyers ask

How many kWh does it take to make one tonne of flour?

About 67–75 kWh per tonne of flour for a complete wheat mill with cleaning, milling, sifting and pneumatic conveying.

What is the installed power of a 100 TPD flour mill?

Reference 100 TPD wheat mills range from about 226 kW to 325 kW, depending on the layout and how much cleaning and conveying is included.

Is installed power the same as the power I pay for?

No. Installed power is the sum of all motors. You pay for energy used, which is roughly the flour produced multiplied by 67–75 kWh per tonne.

Can a small flour mill run on a generator?

Yes, if the generator covers the installed power plus motor starting loads. We send the motor list so you can size it.
