Screw conveyors for more efficient material flows

Hardface delivers prefabricated screw conveyors with abrasion protection optimized for the applications where they will be used. Thanks to increased functionality and performance, our screw conveyors contribute to efficient and trouble-free operation for a long time.

Screw conveyors for demanding material flows

Hardface has long-standing, documented knowledge of durable screw conveyors. Together with our partner and screw conveyor specialists at Wevik Maskin AB, Hardface is the market leader in both new and refurbished screw conveyors. Whether Hardface is to deliver a newly manufactured screw conveyor or a refurbished, the starting point is always the environment for which it will work. Hardface screw conveyors are used in heavy industries where large material flows expose them to aggressive abrasion. Examples of materials are different types of solid fuels, ash, concrete and cement, as well as material flows in the cellulose and pulp industry.

Ceramic or chromium carbide

Application and material flow determine whether the screw conveyor is to be reinforced with ceramic or chromium carbide as abrasion protection. For repair and reconditioning of existing screw conveyors, thermal spraying is used as a cost-effective, fast method that also provides space for flexible solutions.

With Hardface’s extensive experience of screw conveyors and abrasion resistant materials, we always deliver an optimized solution for the most demanding applications. Hardface screw conveyors contribute to better profitability through increased efficiency and performance thanks to longer uninterruptible operations and maintenance cycles.

Which abrasion protection should be used?

  • What material should be transported?
  • In what quantities?
  • Where is the abrasion areas on the conveyor’s blade; top, pressure side, center pipe?
  • What are the tolerance requirements?
  • Problems with the accumulation of, for example, clinging materials
