We, as a company, Stratgem, are purposefully writing this 
informative blog to create awareness and share knowledge 
about pneumatic conveying systems with those who are very 
much interested in them.
Everyone knows that a specific system is required for the 
transportation of dry bulk materials or powders. In this kind 
of process, dry bulk materials or powders are carried, 
transported, or shifted from one destination to another using 
compressed air or gases like nitrogen. The bulk materials, or 
granules, are transferred or shifted through tubes or an 
enclosed conveying pipeline by the collective force of 
pressure, and for that, compressed air or gas is used. Air movers 
such as positive displacement blowers or vacuums can generate 
the pressure and air flow, which are then used to convey the 
materials. That’s why, by controlling the pressure differential and 
air flow, the system can effectively convey or shift the materials 
over certain places or distances.
Air development devices such as fans, root blowers, or 
blowers perfectly create this air flow pressure. The 
pneumatic conveyor system is a cost-effective, or in other 
words, economical, system because it transfers or shifts 
powdered and granular materials successfully with very 
little loss, stops environmental pollution, and keeps the 
materials themselves clean and free of contaminants.
Many process industries, including chemicals and 
detergents, pet food, food and beverage, renewable 
energy, and specialty materials, now rely on Stratgem's 
cost-effective pneumatic conveyor system.
Whenever powder or bulk material is used in a plant, it 
should be transported or shifted in a systematic manner, as 
well as with the help of material handling equipment. These 
systems safely transfer or shift items or objects from one 
place to another, and they typically come in the form of 
conveyors and elevators.
Stratgem, based in Pune, India, creates pneumatic 
conveying systems that are much more reasonable 
and economical than other mechanical systems. Our 
pneumatic conveying systems are completely 
enclosed, reasonably controlled, and easily 
modifiable. Instead of mechanical systems, they are 
more environmentally friendly. Because of their 
enclosed design, they keep the materials conveyed 
safe and free of harmful foreign matter.
There are two types of pneumatic conveying 
systems.
Dilute phase conveying 
system
Dense phase conveying 
system
Each type can convey materials using either a vacuum or a 
pressure method.
These types can be distinguished by their operating principles, 
which refer to the type of material that can be moved and the 
source of airflow.
Dilute-phase pneumatic 
conveying
Dilute-phase pneumatic conveying is 
described as the process of (pressure) 
pushing or (vacuum) pulling particles 
suspended in air from one location to 
another. At low pressure and high 
velocity, the air-suspended particles are 
transferred continuously. 
Mainly, there are two main types of Dilute-

positive pressure 
systems

Dilute-phase pressure 
conveying 
In dilute-phase pressure conveying, a gas, such as 
air, is used to suspend and transport particulate 
materials through a pipeline. This method is the 
most commonly used for transporting dry materials 
because it is nonabrasive, resilient, and has a low 
bulk density over long distances. Such materials

systems
In positive pressure systems, the gas is supplied to 
the inlet of the conveying pipeline at a pressure 
higher than the atmospheric pressure. This causes 
the mixture to flow through the pipeline under 
positive pressure.
How Positive Pressure Systems 
Work
 In this type of system, an air mover, commonly a 
positive displacement blower, is fixed at the start of 
the system to supply a high volume of low-pressure 
air.
A feeder and rotary airlock valve are placed next in 
the line after the blower, which helps to 
methodically "feed" the materials into the line.
As the materials enter the line, an air stream 
  supplied by the blower quickly pushes and 
suspends the particles from one location to another.
The method is commonly used to convey materials 
from a single destination to multiple locations
Dilute Phase Vacuum 
SyVsatceuum ssystems: In vacuum systems, the 
gas is exhausted from the conveying 
pipeline, creating a vacuum that causes 
the mixture to flow through the pipeline 
under negative pressure.

conveying.
To pull material from a storage hopper, a positive displacement 
vacuum provides negative pressure.
The vacuum pump is placed at the opposite end of the line to 
supply the suction needed to pull material from one location to 
the next.
A vacuum relief valve is used to control the negative pressure 
in the system and ensure that the right amount of material is 
delivered to its destination or multiple locations.
 
Dense phase conveying 
sDyensset pehamse pneumatic conveying is the process of 
pushing (pressure) or pulling (vacuum) particles that are 
not suspended in the conveying air. The densely 
transported materials are transferred at high pressure 
and low speed (velocity).
Dense phase conveying is classified into 
two types:
Dense-phase pressure conveying
  Dense-phase vacuum conveying

Dense-phase pressure 
conveying
The dense-phase pressure conveying 
method is commonly used to convey 
abrasive or fragile materials over great 
distances at extremely low speeds.
Beans, cocoa, hazelnuts, cereal, candies, 
and glass particles are examples of 
materials commonly transferred using this 
method.
This system is known for the benefit of 
starting or stopping with the conveying line 
full of material.
 
 
How dense-phase pressure 
conveying works
Material conveyed by this type of method is first loaded 
into a pressure vessel or blow pot.
Once the blow pot is filled, the material vent and inlet 
valve are closed, and compressed air is pushed into the 
vessel.
The compressed air pushes the material from the 
vessel and into the conveying line, where it reaches its 
destination.
"The process is restarted once all of the material in the 
vessel and conveying line has been transferred. It is 
common to install air injectors or jets along the length 
of the conveying line to help boost the material.
 Dense-phase vacuum 
coDennvsee-pyhiansge vacuum conveying systems are used for 
the transport of abrasive or fragile materials over 
short distances at low speeds.
Dense-phase vacuum conveying is commonly used to 
unload materials from rail cars and trucks in a 
fluidized state.

applications.
These types of systems use vacuum pumps to convey 
material from a silo or hopper to a receiving vessel 
known as a vacuum hopper.
When the vacuum hopper is full, the material is then 
ejected to a destination silo. After all the material has 
been conveyed from the silo or hopper, the process can 
be repeated to transfer additional material as needed.
