Lean Phase
Pneumatic Conveying System
Download Full Resolution Image
Two important features of the Lean
Phase Conveying Design combine to provide a
Fluidizing conveying technique which in turn reduces
air pressure requirements. Pressure requirement is
Low.
Lean phase pressure system utilizes low pressure,
high volume (cfm) Air / Gas as the motive force to
transfer powder or granular bulk solid through a
pipeline at High velocity.
Two types of Lean Phase conveying System: Pressure
Type, Vacuum Type
Salient Features
-
Use low pressure, high volume
gas & high velocity for fluidizing to
transfer powder or granular bulk solids up
to capacity 50TPH.
-
Solid to air ratio ( Kg solid /
Kg air) less than 10
-
For lean phase pressure system
conveying length is up to 300mt. approx.
-
For lean phase vacuum system
conveying length is up to 50mt approx.
-
Systems use a positive
displacement blower (Required press. <1bar) to
develop the required motive force.
-
Rotary Valve & Ventury can be
used as feeder in lean phase conveying system.
-
Lean phase systems are most used
on those material which are Non-abrasive,
Non-fragile, light density (typical <800kg/m3).
-
Dust Free Operation.
