Component Specifications

Definition
Helical flighting is a continuous spiral blade or flight wrapped around a central shaft, forming the core working element of variable speed augers. It converts rotational motion into axial material movement through its helical geometry, with pitch, diameter, and thickness precisely engineered to handle specific materials and flow rates. In industrial applications, it provides controlled feeding, mixing, or conveying of bulk solids, powders, granules, or viscous materials.
Working Principle
The helical flighting operates on the screw conveyor principle: as the shaft rotates, the spiral geometry creates a wedging action that pushes material along the axis. The variable pitch design allows adjustment of material flow rate and compression by changing rotational speed, while the helix angle determines the efficiency of material displacement and mixing.
Materials
Typically carbon steel (AISI 1018/1045), stainless steel (304/316), or hardened alloys; surface treatments include galvanization, powder coating, or hard-facing for abrasion resistance.
Technical Parameters
  • Pitch Variable (50-300 mm)
  • Diameter 100-500 mm
  • Thickness 3-12 mm
  • Helix Angle 15-30 degrees
  • Rotation Speed 10-200 RPM
Standards
ISO 7119, DIN 15262

Frequently Asked Questions

What is the purpose of variable pitch in helical flighting?

Variable pitch allows controlled material flow and compression adjustment by changing the distance between flights along the shaft, optimizing feeding rates and preventing clogging.

How does helical flighting handle abrasive materials?

Abrasion-resistant materials like hardened steel or surface treatments (e.g., hard-facing) are used, and flight thickness is increased to extend service life in harsh conditions.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
