dilute phase conveying system quick hp estimate

A Quick Check Method For The Design Of Pneumatic

For powdered and granular materials values below about 15 generally relate to high velocity dilute phase conveying, and values above about 50 indicate that a material is capable of being conveyed at low velocity in dense phase.

SIZING A PNEUMATIC CONVEYING SYSTEM

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 6-12 PSIG, have a terminal velocity of between 4,500 – 6,000 fpm

Dry-air conveying: why it's catching on. - Free Online Library

Oct 01, 1993· Conair product sales manager Pete Stoughton says most dry-air conveying systems operate in a "dilute" phase, meaning there is a high volume and velocity of air carrying the resin. Maximum velocity in a dilute dry-air conveying system should not exceed 5500-6000 ft/min in order to avoid pellets plating out in the high-friction bends of the
