Nov 03, 2020 · Design of Screw Conveyor: The size of screw conveyor depends on two factors 1. The capacity of the conveyor 2. The lump size of the material to be conveyed (Maximum dimensions of the particle) Selection of Screw Conveyor There are many reasons and applications which require variation to standard screw conveyors. These are just some of the factors and conditions that will influence the

handbook of screw conveyor design

Special Conveyor Screw Designs: The double flight design is designed with two rows of flighting that are the same hand (right or left) wrapped around the screw conveyor pipe. This design has an outcome of more evenly dispersed discharge from the system which minimizes surges, this can be particularly desirable when feeding into a scale hopper

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 conveyor with cut and folded flights and

A conveyor screw is either left hand or right hand depending on the form of the helix. The hand of the screw is easily determined by looking at the end of the screw. If the helix wraps around the pipe in a counter-clockwise direction, or to your left (same as left hand threads on a bolt), this is arbitrarily termed a LEFT hand screw
