Shaftless spiral conveyor for difficult waste handling
Efficiently tackle complex waste handling challenges with a design that excels in conveying bulk materials like de-watered sludge and packaged food, ensuring optimal operation with minimal maintenance and seamless integration into existing waste treatment lines.

Conveys and Processes Complex Waste Materials Efficiently
The SSC Shaftless Spiral Conveyor from WAMGROUP is a highly efficient solution for conveying complex and difficult materials in processing environments. With an extra heavy-duty shaftless screw that slides on a wear-resistant liner, it ensures reliable operation without the need for intermediate bearings. This design is vital for handling variable particle sizes and materials prone to tangling, such as urban solid waste, de-watered sludge, and packaged food products.
Designed for challenging applications, it finds use in industries like wastewater treatment, food and beverage processing, and solid waste management. The SSC offers throughput rates up to 45 m³/h for sludge, using drive power ranging from 0.55 kW to 9.2 kW. Constructed from carbon or stainless steel, it includes options for various liners to suit specific material characteristics, ensuring durability and corrosion resistance.
The system is modular, allowing easy integration and customization with options like bolted trough covers and different power transmissions. It ensures an odour-free, fully enclosed operation while providing substantial access for cleaning and inspection, making maintenance straightforward and efficient. The SSC is designed for continuous operation and is particularly suited to applications involving slurries, solids, and cakes.
