Shaftless Screw Conveyors

The unique features of the shaftless screw 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 screw conveyor.

• SPIROLINE^® horizontal and inclined conveying via U-trough. SPIROLINE^®  can be used for inclines up to 30 degrees.
• SPIROLIFT^® vertical and inclined conveying via OK-trough. SPIROLIFT^®  can be used for inclines above 30 degrees.

SPIRAC's horizontal, inclined and vertical shaftless screw 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 screw conveyor is designed to integrate into many configurations.

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 screw 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.
