Special augers

Superior finishing, dimensional accuracy and increased thickness make these augers the ideal solution for pellet and wood chip stoves and boilers

Produced with an increased thickness to satisfy the most demanding companies operating in the pellet and wood chip stove heating industry; these augers are also known as “constant thickness augers”.

Usually produced with flat iron bars, they are now produced by Eurospiral with special superior quality cold rolled steel that bestows considerable advantages to the finished product:

  • Perfectly smooth and clean surface that ensures easier welding and smoother flow of the conveyed material, resulting in reduced friction, stress and noise.
  • Increased accuracy and excellent dimensional consistency.
  • Sharp outer edges, but not cutting.
  • Maximum lengths of pieces, even with short pitches, up to 2300-2400 mm.
  • Possibility of supplying augers cut to specific lengths.
  • Wide range of dimensions.
  • Possibility of purchasing raw materials with special dimensions, for orders of large quantities.
