SPIROLIFT® vertical conveyors feature an octagonal trough and liner. The breaks in the liner provide a resistance point which help to prevent slippery materials forming a rotating plug, thereby encouraging the material to move vertically with the spiral face. 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. 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. 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. SPIRAC conveyors are totally enclosed. There is no spillage of the material being conveyed and odours are completely contained. SPIRAC’s direct-drive design allows a clean and efficient transmission without the maintenance required by belt and chain drives. SPIROLIFT® SPIRAC is the global leader in vertical sludge conveying with hundreds of SPIROLIFT® installations worldwide. This proven technology offers significant cost and operational advantage over alternate methods of sludge elevation and transport. SPIROLIFT® vertical conveyors feature an octagonal trough and liner. The breaks in the liner provide a resistance point which help to prevent slippery materials forming a rotating plug, thereby encouraging the material to move vertically with the spiral face. Wide-faced, short pitch spirals provide a large lifting surface with very little material fallback down the centre of the spiral. Unlike shafted spirals which may suffer from a build up of material around the shaft, especially at the discharge point, shaftless spirals discharge material efficiently to the receiving conveyor. SPIROLIFT® vertical octagonal (OK) conveyors are specially designed to achieve vertical conveying of dewatered sludges and other difficult to transport materials. For more information please contact.
