Re: Hot Mineral Conveying.
Maybe use chains rather than belts.
Or use an en-masse chain elevator if the layout permits. ■
Re: Hot Mineral Conveying.
Cheaper and easier to use dense phase pot if possible. Less maintenance. ■

But more power ? ■
Re: Hot Mineral Conveying.
Mr. Bentzel: Pneumatic Conveying is not an option.
Designer: Would chain be cheaper than a belt conveyor. If chain then which chain would be suitable?
Cast steel 21 Mn4 heat treated or Manganese steel. What should be the thickness of the buckets? 3 mm gauge? Should they have a wear lip for digging etc and additional reinforcements for taking care of warpage at high tempreatures.
Should I consider any additional points other than the above.
Bucket Elevator is the only option for me.
Thanks and regards. ■
High Temp. Conveying.
You are correct in thinking that it is better to use DUNLOp belting with a high heat resistant cover. Fenner Dunlop offer three heat resistant covers, depending on the temperature. For this, you could use a Betahete type cover. This is OK for temperatures at 150 degree constant and with a max. of 170 degree c. But, if the conveyor system is encloesd and the belt doesn't tend to cool down, you are better with something a little better. The Deltahete works up to 200 degree constant and 400 degree max.
The fact is the chain methods are more expensive to renew, and require more power to run.
If you want a quotation for the belt, drop me a line. I am the regional manager for Fenner Dunlop in India (as well as many other areas outside Europe) and can offer a good belt manufactured in the Netherlands.
I'll try and give you further technical advice too and help you understand why we offer exectly what we do. ■

True, but the question is how often does each need replacing?
Material cost is one thing, but downtime plus labour to replace is another. ■
Re: Hot Mineral Conveying.
The renewing of a system with conveyor belting can be done far quicker than the system with chains, so the difference in cost is down to the cost of lost production. I have changed conveyor belts and replaced the buckets from the old belt to the new and have the belt up and running in under a day. Can this be said of a chain system, I think not!!!
The length of time of each option in service really depends on the environment and how the system is maintened, as with anything.

Yes.
PS,
I've got no axe to grind for either belts or chains. ■
Hot Mineral Conveying.
Hi All,
Require some technical help for Conveying of Mineral Concentrate by Bucket Elevators for a project.
The capacity is 40 tph. Bulk density is 2400 kg/cu. mtr.
Operating Temp is 135 Deg Celcius.
Continuous operation . C/C distance is 15 mtrs.
I have thought of using HR grade Conveyor belting from DUNLOP. and Sheet metal buckets and Bearing s with taconite seals.
I would appreciate any heads up regarding my selection. If any of the members have had any experience in this application , please respond.
Can there be any alternatives/ improvements that can be incorporated.
Thanks and regards.
