You list the functional requirements of the reclaimer, material, reclaim rate, pile capacity, then send your enquiry to those companies with a proven track record of installations and they will give a quotation for supply and installation. ■

You appear to be reclaiming from a doghnut pile. I trust it is not the full 360 degrees!

Lubricant must be inert to the sulphur & similarly fire proof etc.

Chain material properties will have similar requirements & if there is a possibilty of sulphate formation you could be in deep clag.

You're looking at 304 (minimum) running in a non combustible fluid film. Really good luck! ■

Who says you need lubricant ???? ■

He did. ■

True, but he doesn't know does he, that's why he's asking.

Now the people who make reclaimers, they'd know wouldn't they. So he should just let them quote according to their knowledge rather than try to tie them up in a specification which might just reveal ignorance rather than knowledge. ■

"I am to specify....."....suggests he isn't leaving it to the so called expertise of the supplier. Many of the problems described in the forums are the result of leaving things to the expertise of the supplier. Chain lubrication can include the idling sheave bearing, at a pinch. Perchance there will be guide rollers on the buckets which will have lubricant; even if sealed for life. ■

.. but the fact he's asking this forum about the chain and lubrication shows he doesn't know what to write in his specification!

IMO the better option would be to get his quotations, see what is being offered THEN ask for comment on the solutions offered.

Seen too many specifications written (even by 'consultants') that clearly show they have no idea what they are talking about. Oh, and they always have the clause that if you don't follow their specification and it doesn't work it's your fault, but if you work to their specification and it doesn't work it's still your fault. As the bard would say "A pox upon them!!" ■
