If you are looking for an efficient and effective system that can handle and transfer powdered and bulk granular materials while ensuring minimal losses, then a powder conveyor is just what you need. The powder conveying device is suitable for different processing industries such as chemical industry, food and beverage, rubber and plastic. Therefore, let us have a detailed understanding of what is the powder conveying device, the different types of powder conveying, the advantages and disadvantages of powder conveying and the working principle of powder conveying.

What is a powder conveying device?

Simply put, powder conveying is a system that uses pressure differentials and gas flow (usually air) to transfer dry bulk materials (powders and granules) from one process area to another. The main principle of powder conveying is to convey bulk cargo through air through closed conveying pipes. Here, the air movement is usually generated by a compressor or a fan.

In order to convey the bulk material through the conveyor line, the flowing conveying air delivers the driving force. This requires a pressure difference between the beginning and the end of the pipe, and in order to overcome this pressure difference, a compressor or a conveying blower is usually used. It also controls the positive/negative pressure airflow in the conveyor line, making it easy for the system to move materials with little loss or damage.

Advantages and disadvantages of powder conveying device

1. The advantages of powder conveying device

Safety: The biggest advantage of the powder conveying device is that the entire process of material conveying is completed in a closed pipeline. Very safe to use. In addition, the powder conveying device has fewer moving parts, which makes it less dangerous for operators and service personnel.

Adaptability: The powder conveying device is flexible and can be easily adapted to any existing equipment. They also save space because they don't need much space. In addition, they can set up multiple feeding points electrically, thus creating an efficient system.

Easy to change lines: The powder conveyor can be routed any way you want-horizontally or vertically. It can easily run long distances. In addition, you can design around your existing equipment.

Less dust leakage and better disinfection: Since the material is transported through a closed pipeline, the material is well contained, which ensures less leakage and dust leakage compared to mechanical conveying systems. Similarly, closed pipes also reduce the risk of product contamination and ensure that the factory remains clean and disinfected.

Easy maintenance: As mentioned earlier, the powder conveying device has fewer moving parts, so the maintenance cost is lower. In addition, each component-tubing, separator, air compressor or pump, and feed device-can be serviced independently. This ensures limited downtime and fast completion of maintenance work.

Structural flexibility: One of the main advantages of a pneumatic conveying system is that it can be custom designed to fit your existing equipment. The conveyor line is light in weight and does not require much structural support. With this system, you can also have multiple input and destination points. In addition, it can also handle longer conveying distances. All these benefits-less space, less maintenance, more flexibility-save you a lot of money and eliminate some potential construction challenges.

2. Disadvantages of powder conveying device

Low energy efficiency: Because air flow is used to move materials from one area to another, powder conveying devices require more power than mechanical conveying systems.

Noise: The noise generated by the blower is quite loud. However, for large blowers, acoustic enclosures are often used.

Not suitable for wet friable materials: Powder conveying devices are most suitable for low density bulk powders (flour and sugar). They are not suitable for larger particle size materials or wet products or combustible bulk solids. In addition, the high speed and sharp turns of powder conveying can damage fragile products and affect the final result.

Larger dust collection system: A larger dust collection system is required to separate the material from the conveying system airflow in the destination area.
