Technical details
- Shaftless screw:
The shaftless screw allows higher filling rates and lower RPMs resulting in less wear and consequently less maintenance and down time. Although the screw 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 screw a very high tensile strength. SPIRAC shaftless screw 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
