Spiral-link drainage belt for sludge dewatering and belt press

Overview

Spiral-link filter belts with no clipper seam – ideal for machines with diagonal belt distortion, worn rolls or heavy pressing force. Round or flat fillers tune air permeability from extreme dewatering (MicroSpiral / F90) to heavy-duty abrasion resistance (HeavySpiral, SpiralHD ExtraLife).

How to choose

  • MicroSpiral / F90 – no fillers, extremely high dewatering for gravity belt thickeners.
  • Spiral F (round / flat fillers) – belt press for mineral, coal, paper and treated municipal sludge.
  • Spiral F-L – low air permeability, good sludge support for municipal belt presses.
  • HeavySpiral / SpiralHD ExtraLife – up to 100% higher wear life for extremely abrasive sludge.
  • No clipper seam – excellent on machines with diagonal distortion or worn rolls.
