A screw conveyor can be used for vertical conveying when the material is suitable and the design is properly matched. This guide explains vertical screw conveyor design, capacity factors, material limits, advantages, troubleshooting points, and selection basics for bulk material handling projects.
A screw conveyor is usually better for short, direct, controlled transfer of heavier, moist, granular, or sticky materials. Pneumatic conveying is usually better for dry, free-flowing powders that need long-distance, enclosed, or flexible routing. This guide helps buyers compare both systems based on material behavior, layout, cost, and maintenance needs.
A screw conveyor is built from matched components, including screw flighting, shaft, casing, drive, bearings, seals, inlet, and outlet. This guide explains screw conveyor parts, flighting types, trough designs, and configurations to help buyers choose the right system for bulk material conveying.
