The small-flake chain is the traction part of a flake-type chain grate. Its links are hinged on pins and pull the flake grate bars continuously along the grate surface.
Structure and how the links are joined
The small-flake chain is assembled from links, pins and clamping clips, with the links joined end to end to form a closed chain belt. Flake grate bars are fixed to the chain by clamping plates and clips and interlock with one another to make a continuous grate surface. Chain pitch and link width match the original specification, and the rims of the front and rear wheels have to be checked at the same time when replacing.
Material and service life
Links are usually Cr25Ni20, and pins can be Cr25Ni20 or Inconel; the typical service lives in the spare-parts list are 12-18 months and 8-15 months respectively.
| Part | Material | Typical service life |
|---|---|---|
| Chain link | Cr25Ni20 | 12-18 months |
| Pin | Cr25Ni20 / Inconel | 8-15 months |
| Grate bar | Cr25Ni20 / Cr26Ni12 | 12-24 months |
Supply and matching parts
The partner factory handles dispatch, and we can supply the small-flake chain to the original pitch, matched with flake grate bars, pins, clamping clips and front and rear wheels. All parts are machined to OEM dimensions and tolerances, and materials can be made to customer requirements. For selection, just give us the grate model and the pitch of the old chain.
