Since you are working in a company specialising in materials handling, can you not ask your collegues for this information? ■

Maybe they want to evaluate their systems / corporate knowledge!!! ■

Hello!

If you need some information.I wish I can help you.sicne we make pneumatic componets. ■

Dear Sachin,

Basic principles of pneumatic conveying are given in several text books. But if your objective is running calculations, a good resource are my articles "Theory and Design of Dilute Phase Pneumatic Conveying Systems" and "Debottlececking Pneumatic Conveying Systems".

I had requested Mr. A.T. Agarwal to forward the article on "Theory and design of dilute phase pneumatic conveying systems" which I have received few days ago. The complex theory of pneumatic conveying has been explained in an extremely simplified way and the guideline for developing an excel program is exhaustive.

However at the end of the article it has been mentioned that formulae for calculation of conveying velocity have been covered in previous articles. A brief guideline for deciding the same shall be extremely helpful. Moreover it is difficult to decide whether the dilute phase or dense phase shall be used for conveying a particular material, e.g. calcined lime - is there any simple guideline for the same? Is there any similar article for the dense phase calculation? Please share these information, if possible so that the aspects of dilute phase w.r.t. the dense phase can be compared.

I shall take this oportunity to thank Mr. A.T. Agarwal for forwarding the excellent article to me. ■
