    Post Reclaimer liner damage problem

    we are experiencing excessive abrasion problem in side chute liner while handling iron ore lumps (-10 to 40mm). Hardox material was used for the same and got damaged within 30 days. Then we used plates with chromium carbide overlay but we apprehend that the life of the same will not be much more. We cannot use Manganese steel liner due to some curvatures.
    Can anybody suggest a suitable liner material for such application for a long duration.

    We are also experiencing a peculiar problem of iron ore lump getting struck in between bucket wheel structure and ring chute structure, creating huge noise and damaging both the structures.

    A suitable suggestion is expected from our experienced friends to solve the problem.

    Liner wear is a matter of choice. There are some very expensive steels available with claims which cannot be substantiated independently. When wear really matters, like in slurry pumps, the manufacturers have calculated the rates of material lost by wearing. Such refinements are unheard of in the dry business. Thicker liners are one answer. Wear will not go away.

    The squealing from trapped rocks is endemic with cell less BWE's and the issue is clearance. Less clearance means less entrapment. To achieve improvement you should reduce the gap and reinforce the chute wall.
