Screw Bin Dischargers provide a low cost, versatile bulk bin discharge facility with many applications in the bulk material handling and processing industries. Based on established Archimedean screw flight principles, our bulk bin discharger design has been continuously developed over many years and is available with options to suit every requirement. All machines are tailored to suit the customer's exact requirements, essential for effective bin or hopper discharge.
In general most free flowing powders, grains, flakes and pellets can be discharged from a bulk bin or bulk hopper with a screw type discharger. To handle materials with poor flow characteristics, features such as steep hopper walls, multiple screws, special flight configurations, additional agitators or other devices may be needed to promote material flow. Please visit our Screw Conveyor page for some additional relevant information.
Discharge rates are controlled by varying the flight diameter, pitch and speed. Bin outlet lengths up to 5m or so can be accommodated and we often use a tapered screw with matching tapered trough to promote an even discharge of material over the length of the hopper outlet.
