Dilute vs. Dense Phase Conveying
Pneumatic conveyance systems have two distinct processes: dilute phase and dense phase. Both are methods of moving bulk materials through conveyor lines.
Understanding the difference between the two conveyance systems is only one of many steps in the selection process. At the most basic level, dilute phase pneumatic conveyance systems are considered fast, typically operating at higher velocities than dense phase pneumatic conveyance systems. Conversely, dense phase pneumatic conveyance systems tend to operate at lower material velocities when compared to dilute phase systems.
Other differences that are often present between the two systems include pressure and additional equipment needs. Most dilute phase systems will run at lower pressures, while most dense phase systems will run at higher pressures. Dense phase systems tend to be more expensive than dilute phase systems, and some of this can be attributed to the need for a compressor and a drier. Dilute phase systems tend to utilize positive displacement blowers.
While speed, pressure, and equipment needs differentiate the systems, the real difference is material. The two systems work better with different materials. Ultimately, the material that will be conveyed will drive the decision between the systems.
How to Choose the Right System for Your Material
ANDRITZ is your partner for clean air technologies, equipment, and services. Our knowledgeable and experienced team can work with you to determine the best equipment to meet your needs. We know that choosing the right system for your material requires consideration of a number of factors. Considerations for pneumatic conveyance systems include the following:
- Conveyance distance
- Line size
- Pressure requirements
- Rate of movement
- Air velocity
Material Matters
The first step to choosing the right pneumatic conveyance system is to choose a partner you can trust. Дастекс®, Геоэнергия®, и Western Pneumatics are now part of ANDRITZ. We are a trusted partner for clean air technologies.
When choosing a system for your material, we understand that material matters. It is important to note that not all material can be conveyed pneumatically. Additionally, not all materials are a good fit for the convey lines. Examples of materials that may not be a good fit for pneumatic conveyance systems include the following:
- Large particles
- Sticky materials
- Slurries
- Pastes
How do you know if a material can be conveyed pneumatically? Most materials that are dry powder, granule pellet, sand, or flake can be conveyed pneumatically. Materials that often fit this description include the following:
- Цементная промышленность
- Fly ash
- Известь
- Flour
- Sand
- Wood pellets
The material will determine which system to choose. For materials that are not fragile and cannot be degraded or destroyed, a dilute phase system may be a good fit. This includes situations where it doesn’t matter if the materials break down.
Dense phase systems tend to be the better option for materials that are abrasive, friable, permeable, or fluidizable. However, other factors should be considered when determining whether the material can be pneumatically conveyed. For example, if the material is sand, an important consideration is particle size. Sand that is not a uniform particle size may not be a good material for a dense phase system because it can plug the line and cause issues.
