Pneumatic conveying is an effective way of handling and moving different types of bulk powdered and granular products with negligible loss and at a lower cost than other systems. These products usually consist of granules or powders. These systems move materials via enclosed, airtight pipes by combining airflow, gas, and pressure. Read More…

Working Principle of Pneumatic Conveying System
A pneumatic conveying system works by moving air through pipes, conveying a propulsion force that moves bulk products via the system from end to end. Pneumatic conveying requires a pressure difference between the system's start and endpoints. This is done through the usage of compressors, blowers, or fans.
The pressure difference relies on several influences, including the system's layout and length and the product's concentration and volume. The specific conveying method will differ between the different conveying system types, whether a dense or lean phase system.
Types of Pneumatic Conveying
There are two primary pneumatic conveying types of systems to choose from: dense phase and lean phase. Each is applied in different uses and has different functions.
Lean Phase Pneumatic Conveying
This is the most commonly used pneumatic conveying system, a lean phase system for granules and powders. Two subdivisions stem from lean phase systems:
Dilute Phase Pneumatic Conveying
Dilute phase conveying systems use gas speeds greater than 17 to 18 m/s with vacuum or pressure below 0.1 bar. In a dilute phase conveying system, material granules/power is wholly suspended in the gas or air stream while the solid loading ratio is considerably lower.
This system is perfect for conveying smooth material with low bulk density. Most systems use fans or side channel blowers to transfer the products along the pipelines.
Medium Phase Pneumatic Conveying
In a medium-phase pneumatic conveying system, the air or gas velocity generally exceeds 17 to 18 m/s with a pressure or vacuum as high as 0.35 bar. Granules/Powder traveling through the pipes remain suspended, with a low concentration or solid loading ratio. Exhauster and root blowers are often applied to push air or gas via the system.
Dense Phase Pneumatic Conveying
A dense phase conveying system is perfect for moving fragile or sensitive products.
These systems can transfer and handle products at low velocities, which helps avoid impact damage to the products. Dense phase systems use pulsations of air to push the products through, followed by another pulsation of both the product and air.
Unlike a lean phase system, a dense phase system needs a more precise calculation for design and proper timing. The overall density, dimensions of the granules/particles, and the route or length will help determine the air ratio to products when utilizing these systems.
Advantages of Pneumatic Conveying
There are several advantages of pneumatic conveying, like:
Pneumatic conveyors can transport long distances either vertically or horizontally.
These systems are simpler to locate because they need less floor space.
The compact design of pipeline transfer lines makes it simple to route pneumatic conveyors around currently used equipment, making it fit in more applications than mechanical systems.
Enclosed nature stops dust from entering the surrounding area and ensures that pollutants don't enter the pipeline.
Operators can maintain a dependably controlled atmosphere.
Multiple pickups and release points are available.
Fewer moving parts imply that they're simpler to maintain when compared to mechanical systems.
Applications of Pneumatic Conveying
The applications of pneumatic conveying include:
Common Applications of Dilute Phase Systems:
Smooth particles like flour
Products which are difficult to break
Light bulk density materials
Common Applications of Dense Phase Systems:
Abrasives like sugar
Materials with heavy-bulk density
Particular friable materials such as carbon black pills
Plastic pellets and more products that do not need continuous delivery
Dense phase conveying
Based on the specifications of an application and the product type needed to transfer and handle, the proper pneumatic conveying system that gets the job done can be acquired.
