A couple of thoughts spring to mind. Sometimes very fine powders can exhibit unusual, reversible, cohesive and adhesive properties as you heat them up in that range. This can cause some real handling problems, so I hope you don't run into the effect.

As for elevating, perhaps a vibrating spiral elevator might be worth considering?

All the best. ■

Dear Mr. Plaut,

Chain-bucket conveyor are already used for conveying / elevating red hot materials and are regularly used in industry. Are these not suitable?

Either use insulated closed bins long distances ( more than 500 mts) or pneumatic conveying( short distances , up to 500 mts).

If you want we can help you out . Either trough the forum or personally, in the forum it is fun and we get may people to collaborate.

If you want a design or even components to be manufactured, we can either design it for you or reccomend somebody to buid it for you. That wil depend on the capacity , distance and whether you want to use the energy or not.

I have done this for 30 years now.

By the way , can your customer use pneumatic conveying ? going up is simple , and 650 C is not really a very high temperature, and of course 10 mts is childs play.

The draw back , you will need to cool the off gass, if you cannot injcorparate it into the process.

Call Paul Solt and he will be glad to accomodate your inquiry.

whatever you do try not to use a bucket elevator.... Just check the existing ones for reference., and then decide. Visit for example the trinidad circulating fludized bed plant. ■
