Lean/Dilute Phase Pneumatic Conveying Systems

Our Lean pneumatic conveying systems function by utilizing low-pressure and high-velocity operations to transfer materials. This conveying technique is particularly effective for moving non-friable and non-abrasive materials that are suspended in air, utilizing a minimal material to air ratio.

For low bulk density powders that have fine particulates and less air retention capabilities, we offer dilute mode conveying. In this mode, the material to air ratio is significantly low, thus ensuring the materials are conveyed in a state of suspension.

With 47+ years of expertise, we have a broad range of installations in India and abroad, serving various applications across numerous industries. Our proven track record is a testament to the quality and efficiency of our pneumatic conveying systems.

Types

There are two types of lean/dilute phase conveying systems-

Positive Pressure Conveying System

Positive pressure systems operate above atmospheric pressure and are used to convey bulk materials over medium distances with greater capacity than using vacuum systems.

With diverter valves, multiple destination delivery one after the other reception points can be arranged easily with positive pressure systems.

Multiple feed points into a common line can also be provided ensuring proper selection and air quantity and special conveying Rotary air lock valves.

Vacuum/Suction/ Negative Pressure Conveying System

Negative pressure conveying systems operate with air pressures below atmospheric pressure.

A vacuum pressure is applied at the destination to suck the material from Rotary Airlock Valve (RAL)) or through suction tool and into the air stream.

With the advantage of gas leakage being inward, the dust injection into the atmosphere is virtually eliminated.

Features

Suitable for transferring wide range of materials for short distances
Variety of particle size, shape or bulk densities can be conveyed
Distribution to multiple areas in a plant and pick-up from several points
Dust free operation, less spillage resulting in good yield recovery

Flexibility in routing – can be transported vertically and horizontally by the addition of a bend in the pipeline
Atomized powder handing ensuring better process controls, less manpower, safety in Plants Total hygiene is maintained due to less exposure of manhandling
