# calculate screw conveyor capacity

Screw Conveyor Capacity Engineering Guide , A 16-inch diameter screw conveyor will convey 2,496 cubic feet per hour at the maximum recommended speed of 80-rpm. The actual screw conveyor speed is calculated by dividing the Selection Capacity by the capacity at 1-rpm. 1,873/31.2 = 60-rpm , Eng.

Screw conveyor design calculation - an Engineering Guide , Define the capacity required for the screw conveyor. The design of the screw must reach a capacity equal or greater than this value. Example : the requirement for a screw conveying sugar is 3500 kg/h. Step 2 : calculate the capacity of the screw conveyor. Assume a diameter D

Screw Conveyor Power Calculation Screw Conveyor Capacity ... , 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

Calculations for Screw conveyors , Calculations for screw conveyors Capacity in m3per hour Q for horizontal transport* Q m3/u = 247,1 x D2- d x s x n x i Capacity in kg per hour Q for horizontal transport* Q kg/u = 247,1 x D2- d x s x n x i x sw D = screw outside diameter in dm d = screw inside diameter in dm s = pitch in dm n = rotations per minute i = degree of trough filling eg. 10%: i = 0,1 sw = specific weight of the material see table
