Shaftless Spiral Conveyors
Shaftless Spiral Conveyors
The unique features of the shaftless spiral conveying systems manufactured by SPIRAC present new possibilities when designing materials handling systems.
The goal at SPIRAC is to manufacture customisable and durable conveying equipment for those industries that demand the highest-quality solid material handling systems available. There is an array of equipment that can help to make that goal a reality, but at the centre of our offering lies our unique shaftless spiral conveyor.
SPIRAC's horizontal, inclined and vertical shaftless spiral conveyors - with no intermediate or end bearings, low RPMs and low power usage - are an extremely reliable conveying option. For many facilities, space is at a premium, which is why the shaftless spiral conveyor is designed to integrate into many configurations.
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.
Material handling can place a lot of pressure on equipment, as many of the industries SPIRAC serves feature harmful, possibly corrosive substances. With a shaftless spiral conveyor, however, maintenance is significantly reduced when compared to traditional conveying methods. The elimination of a central shaft allows a much higher fill rate meaning solutions are more efficient when it comes to conveying, and consequently suffer less wear and power usage.
