Technical details and manufacturing context for Metering Screw/Auger

Definition
A critical component within powder feeder systems that uses helical flighting to transport and precisely meter powdered materials from a hopper to a discharge point, ensuring consistent volumetric or gravimetric flow rates in industrial processes.
Working Principle
The screw rotates within a stationary barrel or housing, creating a positive displacement action that moves powder along its length. The rotation speed, screw pitch, and flight design determine the material feed rate, allowing for precise control of powder dispensing.
Common Materials
Stainless Steel, Carbon Steel, Hardened Alloy Steel
Technical Parameters
  • Screw diameter and pitch dimensions that determine volumetric capacity and flow characteristics (mm) Per Request
Components / BOM
  • Screw Shaft
    Central rotating element that supports the flighting
    Material: Steel Alloy
  • Helical Flighting
    Spiral ridges that move powder along the shaft
    Material: Hardened Steel
  • Drive Connection
    Interface for connecting to motor or gearbox
    Material: Steel
Engineering Reasoning
0.1-5.0 kg/min at 50-500 RPM with 0.5-2.0% mass flow accuracy
Screw deflection exceeding 0.15 mm/meter at 600 RPM or powder bridging at 60° angle of repose
Design Rationale: Helical bending stress exceeding 345 MPa yield strength of 316L stainless steel at critical speed, or cohesive powder arching exceeding 2 kPa unconfined yield strength
Risk Mitigation (FMEA)
Trigger Radial clearance exceeding 0.25 mm between screw flight and barrel
Mode: Backflow leakage causing 15% mass flow deviation
Strategy: Dual-tolerance barrel design with 0.1 mm clearance at feed zone and 0.05 mm at discharge zone
Trigger Powder moisture content exceeding 3% by mass
Mode: Adhesive buildup reducing effective screw diameter by 8%
Strategy: Integrated dehumidification hopper maintaining 25% relative humidity at 20°C
