1. Method and limitations How to design and size a dense phase pneumatic transport line There are few existing methods published to calculate dense phase pneumatic conveying system s but most of the knowledge here stays with specialized suppliers.

As a general rule in pneumatic conveying, when sizing a system we look primarily at pressures, velocities and line loadings to determine best what the line size should be. For example a well sized dilute phase pressure system going 200 feet would probably run somewhere between 612 PSIG, have a terminal velocity of between 4,500 – 6,000 fpm ....
