State-diagram of coarse particles

Posted in: , on 9. Dec. 2007 - 14:51

Hi, Everybody

Have you plotted state-diagram of coarse particles. I need some experimental data to validate my numerical model. Spherical particles with the diameter of over 3mm is preferred.

Thanks in advance for your help.

Comprehensive Conveying Data

Hello Gonski

You will find data on 4 mm nylon pellets on pages 293 to 295 of my book "Pneumatic Conveying Design Guide - Second Edition" published by Elsevier in 2004. The data covers conveying with conveying line inlet air velocities ranging from < 5 m/s to > 30 m/s, with conveying line pressure drop values up to 2 bar and solids loading ratios up to 30. The material was conveyed through a 49 m long pipeline of 81 mm bore with six bends. The material was conveyed by means of a blow tank. Material flow rates achieved were up to 18 tonne/h and the pipeline never blocked on any occasion. Good luck with your research.

Hi, Dr. David Mills

It's my great pleasure to get your response. In fact, some guy has recommended me your book in last year. Unfortunately, the book is not available in the library of our university. Have you published the data in some international journal. If not, is it possible for you to provide me the three pages.

Cheers,

Gonski

Sir, my supervisor agrees to buy your book. Therefore you need not sent me the pages of state-diagram.

Cheers,
