Extending Screw Conveyor Life — Wear, Grip and Coating Options
Screw conveyors and Archimedes screws are workhorse equipment in the water and process industries, running under continuous load for extended periods. Over time, wear on the screw flight surface reduces both material grip and conveying efficiency — and replacement or refurbishment can mean significant downtime.
Why screw flights wear
Continuous contact with the material being conveyed — whether that's sludge, aggregate, or process byproducts — gradually erodes the flight surface. As the surface smooths out, grip on the material being moved reduces, which can reduce conveying efficiency even before the wear becomes a structural concern.
Coating and repair options
Rather than full replacement, a positive-grip, anti-wear coating can be bonded to the existing screw flight (or applied to a replacement component manufactured to the original specification), restoring material grip and adding a wear-resistant surface layer. This is typically a faster and lower-cost intervention than full equipment replacement.
Where this fits with Helion
Helion SpiralTech applies Corrotec's positive-grip surface engineering to screw conveyors and Archimedes screws — bonded to your existing equipment or a replacement component manufactured to spec, designed to extend service life and maintain material grip under continuous load.
