Wrights Dowson Multidirectional screw feed

Applications & Use Cases

• Transferring bulk ingredients like grains, powders, or granules within a processing line.
• Feeding precise amounts of material into mixers, grinders, or packaging machinery.
• Distributing product across multiple discharge points in a controlled manner.
• Handling delicate or friable products with reduced degradation compared to other conveying methods.

Typical Specifications

Typical throughput

Throughput for this class of screw feeder can vary significantly, often ranging from hundreds of kilograms to several tonnes per hour, depending on product density and screw design.

Power supply

Units of this type commonly utilise 400V, 3-phase electrical supplies for the drive motors, as indicated by the twin 2.2kW drives.

Materials of construction

As stated, this unit is stainless steel, which is typical for food processing applications to ensure hygiene and corrosion resistance.

Footprint

Given the 3700mm length per screw, the overall footprint will be substantial, requiring adequate space for installation and maintenance access.

Suitable feed sizes

Multidirectional screw feeders are generally suitable for free-flowing to semi-free-flowing powders, granules, and small particulate solids.

Maintenance requirements

Routine maintenance typically involves checking motor and gearbox function, inspecting screw flights for wear, and ensuring seals are intact.
