Lean phase conveying system

Lean phase conveying system

lean phase conveying takes place when a material is carried in suspension within flowing air. This method transports the material at high speeds throughout the system, remaining suspended in the air. Often known as suspension flow, this process involves particles being held in suspension within the air as they are propelled or drawn through the pipeline.

Dilute phase conveying is defined by its high velocity, low pressure, and low ratio of solids to air.

Our Lean pneumatic conveying systems operate on the principles of low-pressure, high-velocity transfers to efficiently move materials. This method excels in transporting non-friable, non-abrasive materials suspended in air, maintaining an optimal material-to-air rat

Specifically tailored for low bulk density powders with fine particulates and limited air retention, we provide dilute mode conveying. This approach ensures materials remain suspended during transport by maintaining a significantly low material-to-air ratio.

With over 47 years of experience, we have established a strong presence both domestically and internationally, catering to diverse industries with our pneumatic conveying solutions. Our extensive track record underscores the reliability and effectiveness of our systems.

Salient Features

  • Use low pressure, high volume gas & high velocity to transfer powder or granular bulk solids up to capacity 30 TPH.
  • Solid-to-air ratio ( Kg solid / Kg air) less than 10
  • For the lean phase pressure system conveying length is up to 300mt. approx.
  • For lean phase vacuum system conveying length is up to 150mt approx.
  • Systems use a positive displacement blower (Required press. < 1 bar) to develop the required motive force.
  • A Rotary Valve or Ventury can be used as a feeder in a lean phase conveying system.
  • Lean phase systems are most used on those materials that are Non-abrasive, Non-fragile, Free flow, and have moisture content up to 10%.
  • Dust-Free Operation
