Custom Pneumatic Conveying Systems: Tailored Solutions for Unique Industry Needs

One of the key technologies enabling this efficiency is pneumatic conveying systems. These systems are crucial for transporting bulk materials through pipelines using air pressure. However, each industry has unique needs that require tailored solutions. Custom pneumatic conveying systems offer bespoke designs that address specific operational challenges, ensuring optimal performance and compliance with industry standards.

Understanding Pneumatic Conveying Systems

Pneumatic conveying systems are designed to move bulk materials, such as powders, granules, and pellets, through a series of pipelines using air pressure or vacuum. This method is favored for its cleanliness, efficiency, and ability to handle a wide variety of materials. The primary components include air movers, conveying lines, feed equipment, and separation equipment.

Types of Pneumatic Conveying Systems

Dilute Phase Conveying

Dilute phase conveying involves the suspension of materials in a high-velocity airstream. This system is ideal for light, non-abrasive materials and offers flexibility in routing.

Dense Phase Conveying

Dense phase conveying operates at lower velocities and higher pressures, making it suitable for heavy, abrasive, or fragile materials. This system ensures gentle handling, reducing wear on both the materials and the equipment.

Semi-Dense Phase Conveying

Semi-dense phase conveying is a hybrid approach that balances the attributes of both dilute and dense phase systems. It is versatile and can handle a range of materials efficiently.

Key Components of Pneumatic Conveying Systems

Air Movers


Blowers generate the airflow required for dilute phase conveying. They are efficient, reliable, and capable of providing the necessary air volume for material transport.


Compressors are used in dense phase systems to create the high-pressure air needed to move materials through pipelines. They ensure consistent pressure, crucial for handling dense or abrasive materials.

Conveying Line


The piping forms the conduit through which materials are transported. It must be designed to withstand the pressure and abrasiveness of the conveyed materials, often requiring specialized coatings or materials.


Fittings, such as bends and junctions, are essential for routing the conveying line. They need to be designed to minimize material buildup and wear, ensuring smooth operation.

Feed Equipment

Rotary Valves

Rotary valves control the flow of materials into the conveying line. They must be precisely engineered to handle specific material characteristics, ensuring consistent feed rates.

Screw Feeders

Screw feeders provide a controlled and metered feed of materials into the conveying line. They are suitable for materials with varying flow characteristics and ensure a steady supply.

Separation Equipment


Cyclones are used to separate conveyed materials from the airstream. They utilize centrifugal force to remove particles, ensuring clean and efficient separation.


Filters capture fine particles from the airstream, preventing contamination and ensuring compliance with environmental regulations.

Design Considerations for Custom Pneumatic Conveying Systems

Material Characteristics

Particle Size

The particle size of the material affects the choice of conveying method and equipment. Fine powders require different handling compared to larger granules or pellets.

Moisture Content

Moisture content influences the material’s flowability and can cause blockages or caking in the system. Designing for appropriate moisture control is crucial.


Abrasive materials can cause significant wear on the conveying line and equipment. Using wear-resistant materials and designing for minimal contact can mitigate this issue.

System Capacity

Throughput Requirements

The required throughput dictates the system’s design and capacity. Ensuring that the system can handle peak loads without compromising efficiency is vital.

Conveying Distance

Horizontal vs. Vertical

The distance and direction of material transport impact the system’s design. Horizontal conveying requires different considerations compared to vertical lifts, such as pressure drop and material flow dynamics.

Environmental and Safety Regulations

Compliance with environmental and safety regulations is mandatory. This includes dust control, noise reduction, and ensuring that the system does not pose health hazards to operators.

Energy Efficiency and Sustainability

Designing for energy efficiency not only reduces operational costs but also aligns with sustainability goals. Incorporating energy-saving technologies and optimizing airflow can enhance system efficiency.
