Re: 300 °C Application Temperature
At 300 deg C I'd be looking at a different type of conveyor! ■

Its not just a matter of finding a belt, which you won't: there is also the issue of lubricant retention. So if you found a belt & lubricant to do the job you could then start looking for a suitable belt cleaner. Give it up.

300 C (572f) Application
The onlt belt with a construction to handle that temp. is fiberglass. Even with a fibergalss carcass, the EPDM rubber will burn up (harden, crack up & break away from the carcass as it is only good to 400 degree F spkikes (no baking loads). Im with the other guys, to avoid extreme expense, find another way to convey the material.

Re: 300 °C Application Temperature
Hi,
there are special steel belts for process purpose: in your case you could cool the material to a proper temerature to use normal conveyor belts for further conveying... ■
800°C - 1000°C Application Conveyor Belt
Actually, 300°C is not so high temperature. Our newest high temperature resistant conveyor belt can resist 800 - 1000°C high temperature with open or close fire.
The belt uses solid belt made of metal spiral net as carcass with burn-resistant protective cover, characteristic of burn-resistant, high-temperature resistant, fire-resistant, rip-resistant, tearing-resistant, small elongation, strong adhesive strength between plies, excellent trough ability, curing joints by 100%, short and easy splicing operation, its carcass service life is longer and can reach 2.5 times as longer as that of NNEPCC.
We used a special recipe for our cover rubber. Using EPDM, CIIR (Chlorobutyl rubber), SBR as major material, appending Natural Rubber, burning resistant filler and reactant as indirect material.
Our burning and high temperature resistant conveyor belt has already been widely used in many Chinese Steel company, sinter plant, pellet plant and ect.
If you think above conveyor belt is suitable for your application, I will be glad to talk to you.

Re: 300 °C Application Temperature
Does any one of you have some experience with Aramid or other special fibers? What was the maximum temp of the material you have carried on such a belt and what was the maximum temp at the carcass of the belt in such an experience?

Has anyone tried this type of conveyor belts in a real plant? ■
There's A Hole In The Bucket...
..Dear Henry,
Your claims seem rather ambitious. One thousand degrees Celsius is very hot by anybody's stretch of the imagination.
However, even if we give you the benefit of the doubt, how long does the grease in the rollers last? etc etc.
There is a more recent thread running alongside this long forgotten serial where all the respondents have clearly stated or agreed that there are frequent failures of belts running at much lower temperatures than 1000oC. I urge you to reassess you top temperature limit and while you're at it have a look at the bottom limit as well. ■

300 °C Application Temperature
Hello everyone
Can someone tell me what type of reinforcement should be used in a belt if it is supposed to carry loads at 300deg C.?
Thank you
