In dry materials handling, both the product being conveyed
and the application are used to determine the best type
of conveying system.

Highly abrasive products and those subject to degradation
move best through a high-pressure, low-velocity conveying
system. On long distance, high-rate applications, a
high-pressure, low-velocity system can offer energy savings.
Smoot Dense Phase Pneumatic Conveying System
is such a system.

Unlike dilute phase systems, there is not an airlock feeder
for introduction into the line. Dense phase systems use
a pressure vessel or transmitter. While airlocks are normally
limited to a pressure differential of only 15 psig, dense
phase transmitters have no pressure limitation. With their
high-pressure capability, dense phase systems allow for
higher rates and lower velocities in the same line size.
Slugs of product can be “pushed” through while dilute
phase suspends all product in the air stream.

Dense phase could be your best choice—particularly if you
are dealing with abrasive products or products that degrade.
Smoot designs and manufactures both dense phase
and dilute phase systems. We will help you select the best
system for your application.
