Conveying Flyash into Silo

Posted in: , on 26. Dec. 2011 - 19:42

Dear Sir,

I am Pankaj from india and working in ACC Ltd (Holcim Group-Swiss).

I need a calculation sheet for conveying the bulk flyash pneumatically into the flyash silo (26m height).

I want to know:-

1. How much air volume is required to convey 20MT into the 25m silo.

2. Pressure requirement

I will wait for your prompt reply.

Thanks

Dear Mr Pankaj,

I already replied to your thread on the 17th November 2011.

see: Thread: Elevating Flyash Pneumatically into Silo in the section Pneumatic conveying.

You probably missed my reply, because of the time delay between posting a reply and the publication of that reply on the forum.

If that time delay is too long, there will be no message in the New Posts section.


Dear Mr Pankaj,

Your question is not specific enough.

You can use a standard pneumatic, road mobile, bulk tanker.

The compressor air displacement is then approx. 15 m3/sec and the conveying pressure is then approx. 1.8 bar (tank pressure is limited to maximum 2 bar)

The pipeline diameter is 6”.

The filter on th silo should be approx. 30 m2

Complete unloading time (including pressurizing the bulk tank) is then approx. 17 minutes

A smaller compressor requires a smaller pipe diameter.

However, if you are unloading a non pneumatic bulk trailer, using f.i. a rotary valve to feed the pneumatic conveying a lower pressure design should be applied.

In fact, a pneumatic design can be made for a variety of capacities, airflows and pressures.

What is your desired capacity?

More specific information will lead to a more specific response.

Have a nice day
