Description
A screw conveyor or auger conveyor is a mechanism that uses a rotating helical screw blade, called a flighting, within a tube, to move granular materials. They are used in many bulk handling industries.
Screw conveyors in modern industry are often used horizontally or at an incline of up to 90º as an efficient way to move materials, including food waste, wood chips, aggregates, cereal grains, animal feed, boiler ash, meat and bone meal, flour, meal and many others.
The first type of screw conveyor was the Archimedian screw, used since ancient times to pump irrigation water.
219mm augers are typically used in high frequency, medium capacity applications.
The 219mm auger has a capacity of up to 75m³/hr (based on 450RPM flight speed) – but typical capacities are between 12TPH (100RPM) and 35T/hr (280RPM) in ABC Hansen applications.
Power consumptions are:
Horizontal incline 0.34KW/m
45º incline 0.44KW/m
90º 0.57KW/m
All ABC Hansen augers are manufactured with a 90º angle gearbox configuration
Maximum auger length manufactured by ABC Hansen in this configuration: 12m
