Pneumatic Conveying Systems

We specialize in manufacturing and supplying Pneumatic Conveying Systems, Air Pollution Control Systems, and Material Handling Systems. Our expertise and leadership come from Shri Naraindrra Pawar and Shri Rajesh Karale, who have successfully led the organization for over a decade. Our Pneumatic Conveying Systems are designed to provide efficient and reliable transportation of dry materials such as powders and pellets, with features like flexibility, compactness, low maintenance, and weatherproof operation.


Pneumatic conveying systems is a more practical & economical method of transporting solids from one location to another than mechanical conveying (Belt conveyor, Screw conveyor, vibrating conveying, etc.) because of the following three reasons:-

  • These are enclosed and if required can operate without moving parts coming into contact with the conveyed material.
  • Being enclosed is very clean, environmentally acceptable & easy to maintain.
  • Very economical to install & operate
  • Very Flexible in terms of routine & Expansion
  • Can convey any product at any place.

Rajdeep’s proven Capabilities in Conveying System:

  • Conveying Capacity up to 50 Ton Per Hour
  • Conveying Length up to 1000 Mtr
  • Conveying solids BULK Density ranges from 100 – 3500 Kg/m3
  • Conveying with Close Loop System by conveying media Inert Gas (Nitrogen)
  • Solids conveyed like PTA powder, Polyester chips, LLDPE, ESP Dust, Talcum Powder, Grain Flour & many more.

Types of Pneumatic Conveying System

Dilute Phase

Dilute 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.

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 moisture content up to 10%.
  • Dust-Free Operation

Dense Phase

Dense phase conveying occurs when materials are conveyed with air velocities lower than those required for dilute phase over all or part of the pipeline.
Dense phase conveying is often referred to as non-suspension flow. In which the material is conveyed as the full bore plugs separated by air gaps.
The dense Phase is characterized by Low velocity, High pressure & High solid-to-air ratio.

Salient Features:

  • Use High pressure, Low volume gas & Low velocity to transfer powder or granular bulk solids.
  • Specially designed Pressure vessels with valves & air control are the key components of the system
  • Solid-to-air ratio ( Kg solid / Kg air) should be more than 10
  • For a Dense phase pressure system conveying length can be more than 1000 meters
  • These systems use Compressed Air / Gas to develop the required motive force.
  • Dense phase systems are most used on that material which is Abrasive, Fragile, High-density
  • Dust-Free Operation
