Variable pitch flights

Variable Pitch Flights

Variable pitch flights may have a group of flights with an increase or decrease in pitch. These flights are typically used in screw conveyors and screw presses in order to limit the capacity or control flow. Our latest technology allows us to have all sorts of combinations such as variable pitch, tapered OD and ID or flange angle. 

Whether you want a constant pitch throughout the auger or you have a variable pitch requirement, please feel free to contact us. Our technology allows change in helix specification in seconds keeping its true form shape consistently. Flights other then 360 degree turns can be produced easily. 


Recently we have done successful trial on vauted plates. Vautid produce a type of sandwich abrasion resistant plates. This type of plate has a thickness of specifically designed with high strength wear resistant material formed by a special deposition welding method over laying mild carbon steel. Due to its material composition and wear resistant characteristics it has gained immediate attention in number of industries such as highly abrasive (wear) conveyor and screw press type industries.  We see this as an opportunity for augerflights to tackle certain niche markets eliminating the process of hard facing.

Our expertise is in forming auger flights for a range of screw conveyor types;

  1. Decanters
  2. Screw presses
  3. Grit Classifiers
  4. Separators

Material our machines are compatible with 

  1. Mild steel
  2. Stainless steel
  3. High tensile steel
  4. Carbide Plate
  5. Abrasion Resistant Plate
  6. Aluminum
  7. Nickel Alloy 
  8. Sandwich plate (Carbide)
  9. Hardox 450
  10. Bisalloy
