Anti abrasive protection for screw conveyor
Anti abrasive protection for screw conveyor
(OP)
Hello,
We're using screw conveyors for transporting raw material, alumina (Al2O), which is very abrasive. After few days of running the conveyor the blade as well as bearing supports were very heavily worn.
Could you suggest a solution that would help to extend the life of conveyors.
Thanks

And how can I protect the internal surfaces of the bushes (supports)?

For the hanger bearings, perhaps surround with a box, and blow a small amount of air into the box.
Where are you located ?

Alternatively consider a chain conveyor running "en-masse" at very low chain speeds using hard casing liners with case hardened chains.

One application we do have we use carbon steel flights with cheap hard facing on the "drive face" on the outer 1/3rd only.
Bearings are kept well away.

Here is a link to one manufacturer, however most of the material we used, came from eastern Europe.
