Category: Shaftless Spiral Conveyors

Take a look at our infographic below to learn more about the differences between a shaftless spiral conveyor and a shafted screw conveyor. The shaftless spiral conveyor transports difficult, stringy, spongy, sticky, wet, lumpy materials – suitable for a wide range...

Low RPM, Duraflo SPX liners and high resistance to corrosion give a long life expectancy to shaftless spiral conveyors. These two, 21.5m SPIROLIFT sludge conveyors at a 40° incline have been in service since 2009 and we replaced some spirals and...

This project includes shaftless spiral conveyor systems and four round silos with sliding frames. Each of these four large silos has an effective net volume of 840m3 and was manufactured by Permastore. The silos are fed with sludge by a network...

VafabMiljö Kommunalförbund upgraded the biogas facility at the Västerås waste facility to increase biogas production.  It is a plant that primarily digests source-separated food wastes from the region. Other materials that are digested are floating substrates, such as sludge from...

Customizable and durable conveying equipment is essential for today’s sludge systems. An array of equipment can help make that goal a reality, but at the peak of efficiency lie, shaftless spiral conveyors, with expected system life of 20 to 25...

Shaftless spiral conveyors are designed for the transport of otherwise difficult to handle materials, such as municipal dewatered sludge, wastewater screenings, grit, industrial sludges or other sticky, viscous, stringy materials. Available in two designs, U-trough for horizontal or inclines up to...

Al Khumrah is the largest existing WWTP site, located in the southern part of Jeddah City in the industrial area of Al Khumrah District in the Kingdom of Saudi-Arabia.  SPIRAC in collaboration with Watequin supplied the sludge handling, storage and...

When designing a sludge conveyor system, a combination of factors need to be considered when sizing the trough, spiral and drive motor/gearbox: Conveyed material characteristics Trough Size, length and design Spiral diameter, pitch and model Motor power and gearbox RPM...

In the field of material handling systems, there are a number of different options when it comes to conveyors. In this article, we’re going to look at the features and benefits of horizontal conveyors, and how the solution can offer...

The market is filled with different solids handling systems (also known commonly as wastewater material handling solutions), and understandably there are a number of differences between them. This article will compare shaftless screw conveyors with the other options on the market,...
