Can an RBT Single Stage Side Channel Blower Be Used for Pneumatic Conveying?

As a supplier of RBT single stage side channel blowers, I often receive inquiries about the suitability of our products for various applications, one of the most common being pneumatic conveying. Pneumatic conveying is a method of transporting bulk materials through a pipeline using the flow of air or gas. It is widely used in industries such as food processing, pharmaceuticals, chemicals, and plastics to move powders, granules, and other dry materials. In this blog post, I will explore whether an RBT single stage side channel blower can be used for pneumatic conveying and discuss the factors to consider.

Understanding RBT Single Stage Side Channel Blowers

Before delving into the application of RBT single stage side channel blowers in pneumatic conveying, it is essential to understand how these blowers work. These blowers are designed to generate high-pressure air or gas flow with a relatively small footprint and low energy consumption. They operate on the principle of a rotating impeller that accelerates the air or gas in a side channel, creating a pressure difference that drives the flow.

The single stage design of these blowers means that they have a single impeller and side channel, which simplifies the construction and maintenance. They are typically compact, lightweight, and quiet, making them suitable for a wide range of applications where space and noise are concerns. Additionally, RBT single stage side channel blowers are known for their high efficiency, reliability, and long service life.

Suitability for Pneumatic Conveying

So, can an RBT single stage side channel blower be used for pneumatic conveying? The answer is yes, but with some limitations. Pneumatic conveying systems can be classified into two main types: dilute phase and dense phase.

• Dilute Phase Conveying: In dilute phase conveying, the material is suspended in the air or gas stream and transported at high velocities. This type of conveying is suitable for materials that are lightweight, free-flowing, and non-abrasive. RBT single stage side channel blowers can be used effectively in dilute phase conveying systems for short to medium distances and relatively small material flow rates. They can generate the necessary pressure and flow to transport the material through the pipeline, provided that the system is properly designed and sized.
• Dense Phase Conveying: Dense phase conveying involves transporting the material in a more compact form, with a higher material-to-air ratio. This type of conveying is suitable for materials that are heavy, abrasive, or have poor flow properties. RBT single stage side channel blowers may not be the best choice for dense phase conveying, as they typically do not have the high pressure capabilities required to push the material through the pipeline at low velocities. In such cases, positive displacement blowers or compressors may be more suitable.

Factors to Consider

When considering using an RBT single stage side channel blower for pneumatic conveying, several factors need to be taken into account:

• Material Characteristics: The properties of the material being conveyed, such as particle size, density, moisture content, and abrasiveness, will affect the performance of the blower. For example, materials with large particle sizes or high densities may require higher pressure and flow rates to be transported effectively. Abrasive materials can also cause wear and tear on the blower components, reducing its lifespan.
• Conveying Distance and Pipeline Configuration: The length and diameter of the pipeline, as well as the number of bends and fittings, will impact the pressure drop and flow resistance in the system. Longer distances and more complex pipeline configurations will require a blower with higher pressure capabilities.
• Flow Rate Requirements: The desired material flow rate will determine the size and capacity of the blower. It is important to select a blower that can provide the necessary flow rate while maintaining the required pressure.
• Operating Conditions: The temperature, humidity, and altitude of the operating environment can also affect the performance of the blower. For example, high temperatures can reduce the density of the air or gas, requiring a blower with a higher flow rate to maintain the same pressure.

Advantages of Using RBT Single Stage Side Channel Blowers in Pneumatic Conveying

Despite the limitations, there are several advantages to using RBT single stage side channel blowers in pneumatic conveying systems:

• Energy Efficiency: RBT single stage side channel blowers are designed to operate at high efficiency, which can result in significant energy savings compared to other types of blowers or compressors. This is particularly important for applications where the blower is running continuously.
• Compact Design: The compact size of RBT single stage side channel blowers makes them easy to install and integrate into existing pneumatic conveying systems. They can be mounted directly on the pipeline or in a compact enclosure, saving valuable floor space.
• Low Maintenance: These blowers have a simple design with few moving parts, which reduces the need for frequent maintenance and repairs. This can result in lower operating costs and less downtime for the system.
• Quiet Operation: RBT single stage side channel blowers are known for their quiet operation, which is beneficial in applications where noise is a concern, such as in food processing or pharmaceutical facilities.

Example Application

To illustrate the use of an RBT single stage side channel blower in pneumatic conveying, let's consider a food processing plant that needs to transport flour from a storage silo to a mixing tank. The conveying distance is approximately 20 meters, and the desired material flow rate is 100 kg per hour.

Based on the material characteristics and conveying requirements, a 1.3kw High Pressure Air Blower Pump from our RBT single stage side channel blower series would be a suitable choice. This blower can generate the necessary pressure and flow to transport the flour through the pipeline at a reasonable velocity, while maintaining energy efficiency and quiet operation.

Conclusion

In conclusion, an RBT single stage side channel blower can be used for pneumatic conveying, particularly in dilute phase applications for short to medium distances and relatively small material flow rates. However, it is important to carefully consider the material characteristics, conveying distance, flow rate requirements, and operating conditions before selecting a blower for a specific application.
