So it's clinker dust, NOT clinker.

That's a whole different ball game as far as chain conveyors are concerned! ■

You don't need a 500 mm wide conveyor to handle 10 m3/hr of clinker dust , a 315 wide machine running at 0.05 m/s will be quite sufficient and will only need about 1.5 or 2.2 kW to drive it.

Use a case hardened drop forged chain for long life. ■

Is the application of a screw conveyor not more appropriate?

Not when I'm giving the advice

Screw conveyors have their place, but not with clinker dust when the conveyor length requires hanger bearings. ■

Any ideas about the temperatures involved? ■

Temperature also.

May I add inclination too.

We can give quotation if we can get full details. ■

1) are you having a rotary valve or double flap valve to give pressure isolation of the conveyor from the baghouse?

2) are you expecting the conveyor to act as a feeder and give a volumetrically controlled output, or have you sized the required capacity to a value that will never be exceeded?

3) how long is the inlet into the conveyor?

Yes, but so are many other dusts handled in chain conveyors, so use a very slow speed chain conveyor with case hardened components as I said previously. ■

We progress little by little in finding out what is really required

The material density is 800 - 1200 m3/hr

The requirement is two conveyors not one.

The first conveyor is under the outlet of the baghouse and subject to the pressure condition inside the baghouse hopper. Currently it is not required to be a feeder conveyor limiting the extraction rate to 10 m3/hr. (This could cause problems )

Then there is a rotary valve, presumably to pressure isolate the second conveyor.

Finally there is the second conveyor.

It is assumed that by rating the system at 10 m3/hr it will be sufficient to always be in excess of the theoretical dust capacity of 7.25 m3/hr.

But is this assumption correct? Maybe not.

10 m3 will be the maximum volume extracted in 1 hr but on a short time span is 0.17 m3 extracted in 1 minute. When the bags are cleaned will the feed to the first conveyor be limited to 0.17 m3/min? If this cannot be guaranteed then the first conveyor needs to be designed as a feeder to limit the throughput to 0.17 m3/min. Chain conveyors, or screw conveyors, work on an instantaneous rate m3/sec or m3/min. It's no good asking for 10 m3/hr then expecting it to extract 10 m3 for 0.5 hr then nothing for 0.5 hr! 10 m3 in 0.5 hr is actually 20m3/hr throughput.

Food for thought, oh and we still don't know the length of the inlet into the first conveyor. ■

2- flange size: we have limitation for outlet flange of baghouse and the slope of hopper which I have asked for size 500mm

meanwhile I myself prefer mor screw conveyor to chain conveyor because clinker dust is very abrasive and maybe screw conveyor life will be more than chain conveyor, isn't it?

however if you would like to offer screw conveyor it should be without intermediate bearing. what was your experience for the longest screw conveyor without intermediate bearing?

thanks

Dear Mohandes

please give a look to the web site www.magaldi.com.

I refer to the Magaldi Ecobelt conveyor It is suitable for this application and match with your request.

It is a conveyor, completely enclosed in an air-tight casing which guarantees a total environmental protection, avoiding dispersion of dust in the ambient.

The belt of the Magaldi Ecobelt, named Magaldi Superbelt, is made up by the assembly of a high tensile steel fabric belt onto which a series of steel pans, partially overlapped, is fixed.

For more details do not hesitate to contact me directly

Best regards ■

Aren't they a bit expensive for just baghouse dust at 10 m3/hr? ■

with temperatures at 150 > 180 have you given thought to the internal wear on the base and side strips ?

If you are handling dust you will need to have wear protection which will not cause any additional friction and drag on your flights and chain.

You will also need to consider the surface flatness or what undulations you expect.

Not only do you need to consider the fabrication you also need to consider the structure and how you will make the expansion joints along its length.

Many times when we have lined such items repairs and maintanance have not been seriously considered. ■

150-180 deg C is no more a big deal than 50-80 deg C.

The degree of wear protection in a chain conveyor largely depends on the speed of the chain.

At the temperatures quoted with single box conveyor construction, you don't need to worry about casing expansion joints along it's length. You may want to consider expansion supports if the conveyor is long.

The enquiry was for a complete conveyor NOT just the chain ■

hello all,

although this post seems no going further, my comments could help another one who looks for an conveyor or feeder

First of all describe all the process in the way you suppose it will work (what you imaging), all from the beginning to the end including the interface-equipment on both sides

What you expect from the system; what is the goal, what it has to do

Operation Conditions (h/d, d/week, ...)

Ambient temperature (min, max, average)

Place available, distances, relevant sizes of interface equipment (e.g. silo measures, chute)

Better you show us a drawing

bulk material characteristics: abrasive, sticky, hygroscopic, explosive/combustible (min. burn temp.), ..., flowing, bridging, tendency to cake, ...

Gas with bulk: is there a gas, besides air, feed with the bulk (explosive, ... steam, ...)?

Bulk temperatures (min, max, nominal)

Angle of Repose of bulk

Grain sizes (min, max, nominal)

Charge rate m3/h and t/h (min, max, nominal); continuos, dis-continuos (describe)

With that kind of data we can start

and send you, to your e-mail, a quotation

And, by the way, our chain conveyor can handle a bulk temperature of more than 700 oC

with ambient temperatures below -40 oC

regards ■

700 deg C, thats knocking on towards red hot

So what are the chains made of? ■

Hello

These are drop forged fork link chains, material specification will not be given over the internet, but if there is a real project we might share some information.

Troughs are made of boiler plate (Kesselblech)

Regards ■

Originally Posted by bulk.good.solutions

Ah, a challenge! I like a challenge, maybe a few steels it's not likely to be, but that are used for drop forged chains -

• Plain carbon steels e.g. C40 or C45. No their strength come from heat treatment and at 700 deg C they will have annealed out.
• Low carbon, low alloy steels e.g. 16MnCr5, 20MnCr5, SAE8620, 18MnCrB5. No, these are case hardened and the case will annealed out well before 700 deg C

Um, I'll have to return to this later following a bit more research ■

Originally Posted by bulk.good.solutions

According to my data Kesselblech boiler plate is

EN 10028-2, P265GH No1.0425

Max temperature according to specification, 400 deg C

Yield point at elevated temperature (400 deg C) is 150 MPa

So you say it's OK for use at 700 deg C ??? ■

I think a competent supplier reading the entire thread will find sufficient information to offer a quotation. ■

According to specification figures the bed depth will be 5.5mm/m/s of chain speed. So you need a very low chain speed to provide a reasonable bed depth for even a very small chain.

I am also particularly amused by posts which claim to be from competent suppliers and then ask for detail drawings ■

Ah, but what what are they competent in, designing from scratch , or making to someone elses drawings . ■
