PNEUMATIC CONVEYING SYSTEM

Common types of pneumatic conveying systems include:

Dilute Phase Conveying – Uses high-velocity air to transport low-concentration material over longer distances.

Dense Phase Conveying – Moves higher-concentration material in batches, suitable for shorter distances and cohesive materials.

Vacuum Conveying – Utilizes negative pressure to pull material, ideal for loading and unloading storage vessels.

Pressure Conveying – Pushes material using positive pressure, suitable for various destinations and longer distances.

Combined Vacuum and Pressure Conveying – Integrates both systems for versatile material movement.

Lean Phase Conveying – Conveys material at high velocities and low pressure for energy efficiency.

Dilute Phase Fluidized Bed Conveying – Suspends material in an upward airstream within a fluidized bed for improved mixing.

Semi-Dense Phase Conveying – Uses moderate pressure and velocity for stable transport, reducing wear and degradation.

The choice depends on material properties, distance, capacity, and application needs.

Pneumatic conveying systems are versatile and find applications across various industries, such as food processing, pharmaceuticals, chemicals, plastics, agriculture, and more. These systems are adaptable to different materials and can be tailored to fit the specific requirements of the industry.

Choosing the right pneumatic conveying system involves considering factors like –

• Material properties : Powder characteristics including particle size and shape, bulk density, moisture content, abrasiveness, friability, cohesiveness, hygroscopic nature of material, static charge, explosivity ,toxicity, melt point etc are very important to design Pneumatic Conveying System for particular application.
• Conveying distance : Overall distance from source point to destination as well as direction and distance of pipeline runs (horizontal and/or vertical) are important to select size of conveying pipe.
• Transfer capacity : This calculation incorporates factors such as powder properties, transfer distance, and the packaging of the powder to be transferred.
• Transfer rate : how fast/frequently does you powder need to be transferred?
• Pipeline bore , Pressure available, Conveying air velocity are several other factors that are considered while designing a system for a particular application.
• Note : Product testing should always be conducted to ensure the method of conveying that is chosen will work properly.

A Powder Transfer System is an automated solution designed to safely and efficiently transport powdered or granular materials from one location to another. It utilizes various mechanisms such as vacuum, pressure, or mechanical conveyors to move powders without manual intervention. This system is commonly used in industries like pharmaceuticals, chemicals, food processing, and manufacturing to streamline material handling, reduce contamination risks, and improve operational efficiency.

In a vacuum transfer pneumatic system, materials are conveyed through a closed pipeline using a vacuum or negative pressure. This method is suitable for pulling materials from one place to another.

In a pressure transfer pneumatic system, materials are pushed through a closed pipeline using positive pressure generated by a blower or compressor. This method is effective for pushing materials from a source to a destination.

In summary, vacuum transfer pulls materials with negative pressure, while pressure transfer pushes materials with positive pressure.
