SPIROLINE® Horizontal-Inclined Shaftless Spiral Conveyors

SPIROLINE® Horizontal-Inclined Shaftless Spiral Conveyors

SPIRAC is the global leader in shaftless spiral conveying and manufacturing with thousands of installations worldwide. This proven technology offers significant cost and operational advantage over alternate methods of screenings, grit and sludge transport.

SPIROLINE® conveyors feature a U-trough with a low RPM shaftless spiral riding on a special low friction long life trough liner.

Material handling can place a lot of pressure on equipment, as many of the industries SPIRAC

Technical details

• Shaftless spiral:The shaftless spiral (screw) allows higher filling rates and lower RPMs resulting in less wear and consequently less maintenance and downtime. Although the spirals can be made out of many different materials, the primary material is a special steel from Sweden which has mechanical properties that give the SPIRAC spiral a very high tensile strength. SPIRAC shaftless spiral conveyors are designed for the transport of otherwise difficult to handle materials, such as municipal dewatered sludge, wastewater screenings, grit, industrial sludges and other sticky, viscous, stringy materials.
• No intermediate or end bearings:Not having intermediate and end bearings allows a comparative reduction in major maintenance work. It also allows efficient and direct transfer – horizontal, inclined or vertical – into another conveyor.
• Liners: SPIRAC’s proprietary liner, DURAFLO® SPX, is designed specifically to ensure long life. The DURAFLO® SPX liner has a built-in wear indicator with a snap-in, snap-out feature enabling easy replacement.
• Totally enclosed troughs: SPIRAC conveyors are totally enclosed. There is no spillage of the material being conveyed and odours are completely contained.
• Direct drive: SPIRAC’s direct-drive design allows a clean and efficient transmission without the maintenance required by belt and chain drives.
