• ### 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. 60-rpm is the correct speed for a 16-inch diameter screw conveyorCalculations for Screw conveyors - Bechtel GmbH,Screw conveyors Belt speed in m per sec Calculations for screw conveyors Screw diameter (in meters) Rotations per minute x 3,14 x 60 Calculations for screw conveyors Power in Kw (P) Q x L x K 3600 x 102 P = power in Kw Q = capacity in 1000 kg per hour L = conveyor screwScrew conveyor design calculation - an Engineering Guide,If the calculated speed at step 2 is < than the max speed for the screw diameter selected, the design can be kept. If the calculated speed at step 2 is > than the max speed for the screw diameter selected, the design is not suitable and the calculation must be run again by changing a parameter, typically the diameter.
