Re: Heat Resistant Rubber Conveyor Belt
Dear Mr. Mustafa,
Referring to your query about the belt to convey hot material at 210 deg C, with a peak temp up to 350 to 450 deg C, the best way would be to refer to the leading manufacturers in the world for the possible belt.
There are two issues. One is the average actual temp the belt will acquire during the operation. The belt should be able to perform in this situation. The other issue is that the localised hot spots should not ignite the belt material.
Referring to the belt literature from one of the German make, they mention continuous or sustained temp around 200 deg C and peak temp up to 240 deg C. They also mention that this belt is capable to withstand the localised hot spot temp of up to 500 deg C etc. Whether such belt will suit your application or not, can only be stated by the belt manufacturer. Possibly, they will ask the method of feeding, conveyor profile, prevailing ventilation or natural cooling condition as the material is being conveyed forward, etc. It will also depend upon the lump size. The feeding should ensure bare minimum abrasion action on the belt cover. The return run should promote the cooling of the belt to the extent possible.
Although I do not have specific answer to your question, but above information may be of help to you for doing needful in the matter. I do not mention the name of supplier in such public forum.

Re: Heat Resistant Rubber Conveyor Belt
Thanks for the reply.
Would you refer goodyear's solar shiled? ■
Re: Heat Resistant Rubber Conveyor Belt
Sir,
we also have a belt that fits your spec. We sell it globally and have no complaints!!
It's specification is 200 degree constant and 400 degree max. (celcius). Be assured that we sell this belt to many cement manufacturers and many will use nothing else, such is the quality. Being the biggest manufacturer world wide means we are also constantly improving our compounds to stay ahead so I'm sure that you'd find it works 'quite well' in operation.
If you want me to make you up a quote, please drop a line to me. If you need any further technical advice concerning this or other matters, you can also contact me. Where in the world, exactly, is your plant?

Dear Stan
I understand that it is not only the rubber compound but also the carcass type which plays an important role if the temperature of material goes up more than 200deg C. How do you take care of this in your belt?

Re: Heat Resistant Rubber Conveyor Belt
This topic is almost 3 years old, but some new questions...
The Dunlop belt still is available and used on clinker installations all over the world with great success.
The peak temperature is not so much an issue, I've seen specs of 450 deg C peaks, however that's about the level at which rubber will start to ignite/burn. Heat resistancy is more a matter of how long the belt can take the heat, so lifetime. That's where most fail.
High heat on standard EP (polyester/nylon) belts can be a problem as the high temperature on the fabrics can cause excessive elongation. That's why already well designed fabric constructions are used. However when temperatures maintain high troughout the process, a switch to steel reinforced belting is preferred, like Dunlop Ferroflex. ■
Re: Heat Resistant Rubber Conveyor Belt
Thanks Rob, I too felt that a normal EP fabric may not work. But what are the other "well designed fabric constructions" you have meant? Are you talking of special fibers..like what?

I only meant to say that fabric constructions and Polyester and Polyamide cords used today have developed also throughout the years, reducing the effect. ■

Heat Resistant rubber conveyor belt
Dear All,
I have to buy heat resistant rubber conveyor belt for clinker (in cement). Can anybody tell me which one is the best in market. My user has descirbed the requirement as described below.
temperature of material is 210 centigrade,
belt temprature is 210 centigrade,
and peak temperature will be 350 to 450 centigrade.
According to my study, I found Goodyear's solar shield as the one that mostly fits in my criteria. Even, it resists upto 205 centigrade. Can anyone tell me a better product, or, as another choice, will it be better to use Goodyear's solar shiled in the circumstances described above? ■
