Leading Pneumatic Conveying System Manufacturers

Design of Pneumatic Conveying Systems

Pneumatic conveying systems are engineered solutions designed to efficiently transport bulk solids, powders, and granular materials through enclosed pipelines using airflow. The design phase is crucial and relies on a blend of scientific principles, real-world test data, and industry expertise. Mathematical models, test data, or a combination of both may be used to design a pneumatic conveying system. If mathematical models are to be used, some level of assurance regarding their fitness for a certain purpose, such as transmitting a specific material under precisely defined conditions, must be established before they are used. System design makes heavy use of test results. This information may have come from a testing facility or from sharing experience from a real plant.

It is crucial that the data pertain to the same grade of material that the new plant design is needed for. The data must also be supplied for a conveying line’s marginally lower level of intake air velocity and a marginally higher level of solids loading ratio than those considered for the new design. Existing data should never be scaled beyond limitations of known transmitting. As you evaluate pneumatic conveying system design for your facility, consider whether the design approach aligns with the specific properties of your material and the performance targets of your process.

Key Elements in Pneumatic Conveying System Design

Effective pneumatic conveying system design involves careful attention to multiple factors, including:

• Material characteristics: Flowability, particle size, bulk density, and abrasiveness.
• System capacity: Required material transfer rates and throughput.
• Pipeline layout: Distance, bend radii, and changes in direction.
• Airflow requirements: Pressure, velocity, and air-to-material ratio.
• Energy consumption: Optimizing blower or compressor sizing.
• Safety and compliance: Dust control, ATEX compliance, and food-grade standards.

Structure and Functionality of Pneumatic Conveying Systems

At their core, pneumatic conveying systems are composed of several integrated components that work together to move bulk materials efficiently and safely. The primary elements include a material insertion point (feed hopper or inlet), conveying pipelines, a receiving point (discharge hopper or silo), and an air movement device such as a blower or vacuum pump. These systems are highly adaptable, with configurations tailored for specific industries and applications—from food processing to chemical manufacturing and plastics handling.

Pneumatic conveying system pipes are adaptable and may be routed around machinery, allowing them to be installed in existing locations. A practical, affordable method of moving products from point A to point B, well-designed pneumatic conveying systems are more efficient than competing mechanical systems. These systems offer a complete enclosure that minimizes dust emissions and contamination, supporting both industrial hygiene and regulatory compliance.

A pneumatic system is an industrial conveyor system that can travel large distances vertically or horizontally and provides protection from dust emissions into the air. Comparatively speaking, mechanical conveying systems, maintenance, equipment, and operating costs are decreased. Pneumatic conveyors also allow for multi-point loading and discharge, making them ideal for process plants with complex material flow requirements.

Pneumatic Conveyor Applications

• Transport of powders, granules, pellets, and flakes in food, chemical, pharmaceutical, and plastic industries
• Transfer of bulk materials in cement, mining, and mineral processing plants
• Dust collection and recycling in manufacturing environments
• Ingredient handling in bakery, beverage, and dairy plants
• Closed-loop conveying for inert material transfer in hazardous environments

Pneumatic Conveying Methods

The materials are moved using air streams, either vacuum or pressure, and there are three main types of pneumatic conveyor methods: dense phase conveying, dilute phase conveying, and air conveying. These methods operate in relation to, and in accordance with, the specific velocities, pressures, and air to commodity ratios within the system. Each method is suitable for different types of bulk materials and transfer requirements.

Dilute Phase Conveying

Continuous, high velocity, low pressure, and high air-to-commodity-loading ratio processes are used in dilute phase conveying. Pulling or pushing material through an airstream at a certain speed helps the process. Positive pressure, vacuum (negative pressure), or a combination of the two can be used to build the system. Dilute phase pneumatic conveying is ideal for lightweight, non-abrasive materials such as flour, sugar, and plastic pellets, and can efficiently handle long conveying distances.

Dense Phase Conveying

Dense phase conveying operates at lower velocities and higher pressures, making it suitable for fragile, abrasive, or heavy bulk materials—such as minerals, cement, or specialty chemicals. This method reduces material degradation and minimizes pipe wear, making it a preferred choice for applications requiring gentle handling or high throughput. Dense phase systems often utilize plug flow or pulse flow to move materials in a controlled manner.

Vacuum vs. Pressure Systems

Pneumatic conveying systems operate without exposing the materials being moved to moving parts because they are enclosed. Pressure systems input compressed air at the insertion or system inlet to force materials through, while pneumatic vacuum systems administer a vacuum at the receiving end to pull the material through the enclosed pipes. The selection between pressure and vacuum conveying depends on plant layout, material characteristics, and hygiene requirements.

• Vacuum systems: Ideal for multiple pickup points and short distances, especially where dust control is critical.
• Pressure systems: Better suited for long distances and multiple discharge points. Suitable for dense phase conveying.
