Screw Conveyor Power Calculation

For a length L of the screw conveyor (feeder), the power PH in kilo watts is the product of the mass flow rate of the material by the length L and an artificial friction coefficient λ, also called the progress resistance coefficient. PH = Im.L. λ.g / 3600 (kilowatt) = Im.L. λ / 367 (kilowatt) Where, I m = Mass flow rate in t/hr
