Air velocity for powder transfer through pipes
Air velocity for powder transfer through pipes
(OP)
I am after some rule of thumb design info looking at recommended air velocity requirements for transporting powder through pipes,
The application is for a a system where material is fed off a vibrator in air, rather than coming in a compacted form
I have a recollection of using 15 - 25 m/s as a velocity and an air:powder mass ratio of between 20:1 and 10:1 respectively a few years ago on another job, but can't find any of my old references, just to check I am in the right ball park.
Thanks

Search for information, white papers etc. under the topic of "pneumatic conveying".
There seem to be no rules of thumb in this field..
The cheapest decision may be to have a sample tested...
Try "dynamic air" www.dynamicair.com
