9 Conveying

The advantages of dense phase conveying over dilute phase include: considerably lower product degradation from particle-wall collisions and much lower energy costs because the air velocities are much less than during dilute phase flow. However, the pressure in a dense phase system operating in plug flow is often higher than a dilute phase system.

Nov 22, 2016· Dense phase pneumatic conveying is a relatively low-speed system where the material is not suspended in the air stream. The low velocity of dense phase means less wear and tear on both the system and the materials being conveyed. The velocity is typically set between 400 ft./min. and 1,000 ft./min., though there are several forms of dense ...

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 ...

Dilute & Dense Phase Conveying - Industrial Accessories ...

Unlike in dilute phase, materials conveyed in dense phase are not suspended in the air because they are extremely abrasive and/or extremely heavy. Dense phase is also operated at a much lower velocity than dilute; typically around 700-1,500ft/min. Materials that are more than 55-60lbs per cubic foot are good candidates for dense phase conveying.
