Hello!

I am Airslide design for fly ash. I don't know how to calculate the required airflow for Airslide. I would like to ask for documentation about the calculation of the airflow level applied to the Air slide.

Available data:

Bulk density of fly ash: 0.7 (Ton/m3)

Mean Particle Size: 100 (micromet)

Air slide capacity: 200 (Ton/h)

Any help will be much appreciated.

Thanks!

Most texts about pneumatic conveying cover airslides as an offshoot.

It might help if you mentioned the dimensions of a proposed slide.

Thanks for the reply. The proposed size of air slide width is 400, length 2000.

Dear Ducvan,

The software is part of a complete proprietary pneumatic conveying calculation program and is not available

The Fly Ash Remains A Lot In The Tank

Dear dungnguyen,

Why you use the bulk cement carrier to carry fly ash?

This is a question to yourself


the fly ash remains a lot in the tank

I understand that you are actually transporting fly ash in a bulk truck tanker and that there seems to be fly ash left in the tanker after unloading.


Is there any solution to fix this problem?

First, cement bulk trucks are widely used for fly ash without problems.

Why, in your case, there is a lot of fly ash left behind in the tank is not easy to say without more information.

The main causes, that I can think of, are:

-Fly-ash flow properties

-Bulk tank design (tilted, outlet hoppers)

-Sufficient fluidization before starting the unloading.

-Valve operation sequence.

-Condition of the installation. (leakages)

-Combination of the above

Do your own research, find the cause, and fix the problem
