Lining of gutter troughs
Linings for gutter troughs are used for protection in the following situations:
- Wear due to screwed-in grinding inserts made of S 235 JRC up to hard materials such as XAR30, Hardox®, Dillidur®, C reusabro®, manganese hard steel, ceramic plates (for extremely high wear and temperatures) or welded composite plates such as E IPA®, Vautid®.
- Caking or chemically aggressive conveyed material due to screwed-in inserts made of stainless chrome-nickel steels or plastics such as
RC H1000®, Kalen® or Teflon® or bonded rubber inserts. - Coating systems can also be used in special cases.
Structural steel S 235 JRC is usually used as the material for vibratory equipment.
This can be easily formed and welded; its wear resistance is sufficient for most applications. Particularly resistant special steels are used for higher wear loads. Oxidation-resistant chromium-nickel steels, such as V2A or V4A, are used for foodstuffs, adhesive or aggressive substances.
Temperature-resistant and heat-resistant steels (e.g. Novotherm®) are available for working conditions with temperatures of up to 900 ˚C.
