A custom industrial screw conveyor is a mechanical handling system that uses a rotating helical screw blade (flighting) within a tubular or U-shaped trough to move bulk materials horizontally, vertically, or at an incline.
As the screw shaft rotates, material fed into the housing is pushed forward by the flighting. Enclosed designs prevent dust and odor emission during transfer, ensuring clean plant operations.
Every conveyor is engineered to match your required throughput, material characteristics, and plant layout.

Every custom screw conveyor undergoes strict quality inspections and trial runs before leaving our facility.
Raw Material Inspection: Strict verification of steel plate thickness, grade compliance, and material certification through spectrometry checks.
Dynamic Balancing: Precision balancing tests performed on long screw shafts to eliminate vibration, ensure smooth rotation, and prevent premature bearing wear.
Pre-Shipment Trial Run: Simulated test runs conducted in-house to verify drive performance, sealing integrity, and noise levels, complete with inspection reports.
Quick answers to common technical and purchasing questions regarding custom industrial screw systems.
A: Shafted conveyors feature a central pipe with welded flighting, ideal for horizontal or mild inclined conveying of dry, free-flowing powders. Shaftless conveyors use a heavy spiral helix without a central shaft, making them perfect for sticky, viscous, or high-moisture materials like wastewater sludge without clogging.
A: Conveyor capacity depends on trough diameter, screw pitch, rotational speed (RPM), and material bulk density, as well as a filling factor (typically 15% to 45% depending on material abrasiveness). Our engineering team can accurately calculate your precise requirements based on your plant data.
A: For corrosive or food-grade applications, 304 or 316L stainless steel is recommended due to its superior chemical and oxidation resistance. For abrasive minerals or heavy wear applications, we utilize wear-resistant alloy steels or integrate UHMWPE trough liners to significantly extend equipment lifespan.
