12 Must-Know Considerations for Pneumatic Conveying Design

Next time you stroll through the grocery store, casually picking up a bag of flour or sugar, take a moment to ponder the intricate process involved in packaging these seemingly simple items.

Handling materials with fine particle sizes necessitates specialized techniques to ensure minimal damage or loss, which is where pneumatic conveying system comes into play.

Pneumatic conveying or chain conveyor operate by transporting materials through enclosed conveyor lines, utilizing a combination of pressure differential and the flow of air generated by a blower or fan.

These systems are versatile and capable of transporting various powdered or granular bulk materials such as cement, starch, sugar, salt, polymers, and plastic powder.

However, designing an effective pneumatic conveying system requires careful consideration of several key factors to ensure optimal performance. In this blog, Intech Engineers– one of the trusted Pneumatic Conveying Manufacturers will tell you about the 12 must-know considerations for pneumatic conveying design.

  • Material Properties: Understanding the properties of the material being conveyed is crucial for designing a successful pneumatic conveying system. Factors such as particle size, density, shape, and abrasiveness can significantly impact the system’s performance and determine the appropriate conveying velocity and air-to-material ratio.
  • Conveying Distance: The distance over which the material needs to be conveyed plays a vital role in system design. Longer distances may require higher air velocities and larger pipe diameters to maintain the desired material flow rate and minimize the risk of pipe blockages.
  • Conveying Rate and Capacity: Determining the required conveying rate and capacity is essential for selecting the appropriate equipment and sizing the system components. Factors such as material characteristics, production demands, and batch sizes must be considered to ensure efficient and reliable conveying.
  • Air Supply and Pressure: The availability and quality of the air supply are critical for successful pneumatic conveying. Sufficient air pressure must be maintained throughout the system to prevent material settling or blockages. It is important to assess the air compressor capacity and the possibility of pressure drops due to pipe friction.
  • System Layout and Pipe Routing: Proper system layout and pipe routing are essential for smooth material flow and minimal pressure drops. The layout should minimize the number of bends, elbows, and changes in pipe diameter to avoid unnecessary air turbulence and system inefficiencies.
  • Material Degradation and Contamination: Some materials may be prone to degradation or contamination during pneumatic conveying. Careful consideration must be given to the selection of materials for the system components and the implementation of appropriate measures to prevent material degradation or contamination, such as using smooth pipes, filters, and separators.
  • Filtration and Separation: In pneumatic conveying systems, it is important to incorporate effective filtration and separation devices to remove dust, fines, and foreign particles from the conveyed material. These devices help maintain product quality, prevent equipment damage, and ensure a clean working environment.
  • System Control and Monitoring: Implementing an efficient control and monitoring system is crucial for optimizing the performance of a pneumatic conveying system. Pressure, temperature, and flow sensors can provide real-time data to enable adjustments and identify potential issues promptly.
  • Material Segregation: Certain materials may segregate during conveying due to differences in particle size or density. Understanding the segregation tendencies of the material and implementing appropriate measures, such as using flow aids or modifying the system design, can help minimize segregation and ensure consistent product quality.
  • Safety Considerations: Pneumatic conveying systems involve the handling of potentially hazardous materials and the operation of high-pressure equipment. You should implement the adequate safety measures, including proper grounding, explosion protection, and personal protective equipment to ensure the safety of personnel and prevent accidents.
  • Maintenance and Accessibility: Designing a pneumatic conveying system that is easily accessible for maintenance is essential for minimizing downtime and ensuring optimal performance. Components such as valves, filters, and elbows should be positioned for easy inspection, cleaning, and replacement when necessary.
  • Energy Efficiency: Energy consumption is a significant consideration in pneumatic conveying systems. In the long run, designing an energy-efficient system may save you a lot of money. Techniques such as optimizing pipe sizing, reducing pressure drops, and implementing variable frequency drives for motors can help improve energy efficiency.

Designing a pneumatic conveying system or belt conveyor requires a comprehensive understanding of the material properties, conveying requirements, and system components. Considering the above key factors discussed in this blog post will help ensure an efficient, reliable, and safe pneumatic conveying system.

By addressing these considerations during the design phase, industries can optimize their operations, minimize downtime, and achieve better overall performance in material handling and transport.
