Shaftless spiral conveyor for waste water treatment
Efficiently handle challenging materials like de-watered sludge and screenings with a shaftless spiral conveyor, designed to prevent tangling and ensure smooth material flow. Ideal for operations needing robust solutions to manage diverse waste types and maintain continuous processing without intermediate bearing obstructions.

Conveys and Manages Difficult Waste Materials
The Shaftless Spiral Conveyor SSC from WAMGROUP is engineered for efficient handling of challenging waste materials. This equipment is distinguished by its shaftless design, allowing for the transport of sticky, tangled, or highly variable materials without clogging, thanks to its robust, wear-resistant spiral. Ideal for applications in wastewater treatment and food processing, the SSC can manage diverse wastes like sludge cake, packaged food waste, and industrial slurries.
Production processes benefit from its simple design and minimal maintenance, with a throughput of up to 45 m³/h for sludge. The conveyor’s energy efficiency is enhanced by a variable-speed motor, and its material construction choice between carbon steel and stainless steel offers excellent corrosion resistance. Automation is facilitated through PLC control, while its modular components and various liner options allow for tailored solutions to fit specific operational needs. The design includes features for easy access and cleaning, ensuring quick maintenance and uninterrupted operations.
