In the production process of modern industry, the material conveying method is directly related to the production efficiency and cost control of the enterprise. Pneumatic conveying, as an efficient and environmentally friendly material conveying technology, has gradually become the first choice of more and more enterprises, while traditional conveying methods (such as belt conveying, screw conveying, etc.) still have irreplaceable advantages in many occasions. Today, we will use "high-speed rail" and "green train" to compare the difference between pneumatic conveying and traditional conveying to help everyone understand the advantages and limitations of the two more intuitively.
1. The basic principle and working method of pneumatic conveying
The pneumatic conveying system is a technology that uses the power of airflow to transport materials to a specified location through a pipeline. According to different conveying requirements, pneumatic conveying can be divided into two categories: dilute phase pneumatic conveying and dense phase pneumatic conveying.
Dilute phase pneumatic conveying
In this type of system, the ratio of material to airflow is low, and the material is suspended in the airflow, which is suitable for long-distance and low-yield conveying.
Dense phase pneumatic conveying
The ratio of material to airflow is high, and the material is transported in the airflow in a dense manner, which is suitable for large flow and short-distance conveying.
Working Principle
The pneumatic conveying system generates airflow through an air source (such as a blower or compressor) to transport materials to a designated place through a pipeline. The speed and pressure of the airflow determine the efficiency of the conveying and the flow state of the material. The advantage of pneumatic conveying is that it can be operated automatically on a large scale, reducing manual intervention and reducing costs.

2. Traditional conveying methods: belt, spiral, and vibration conveying
Traditional conveying methods mainly include belt conveying, spiral conveying, and vibration conveying. Most of these methods rely on mechanical power, and the materials are usually in contact during the conveying process.
Belt conveying
It is suitable for large-scale and continuous material conveying and is widely used in coal mines, mining, metallurgy and other industries. Its advantage is that it can convey larger particles of materials and the conveying process is stable.
Picture
Spiral conveying
It is suitable for conveying small and medium-sized flow materials, especially for conveying powdered and granular materials. It is commonly used in feed, fertilizer, grain and other industries.
Picture
Vibration conveying
Relying on the force generated by vibration to push the material to the front end, it is suitable for dry and uniformly granulated materials, especially for conveying over shorter distances.

Although these traditional methods still dominate in some areas, they have limitations in material transportation over long distances and complex terrain.
3. Pneumatic conveying VS traditional conveying: a graphic comparison of high-speed rail VS green-skinned trains
After understanding the basic concepts of pneumatic conveying and traditional conveying, we can analyze the difference between the two more vividly through the comparison of "high-speed rail" and "green-skinned trains".
High-speed rail: Advantages of pneumatic conveying
Efficiency and speed
One of the biggest advantages of pneumatic conveying is its high speed and efficiency. Just as high-speed rail can cover long distances in a short time, pneumatic conveying can also transport materials from one place to another at a higher speed and efficiency. The pipeline network of pneumatic conveying can cover the entire production line, greatly improving production efficiency.
Automation and intelligence
The operation of high-speed rail depends largely on automation systems, and pneumatic conveying has similar characteristics. The pneumatic conveying system can be seamlessly connected with the company's production control system to achieve fully automated material transportation. This means that manual intervention can be reduced, operating costs can be reduced, and the accuracy and stability of material transportation can be improved.
Environmental protection and safety
Pneumatic conveying uses airflow to convey materials, which does not generate a lot of dust, reduces environmental pollution, and meets the green production requirements of modern enterprises. Moreover, since there are no large number of contact parts, the materials conveyed by pneumatic conveying are less polluted and worn, and the system is more stable.
Green train: limitations of traditional conveying
Low speed and restrictions
Traditional conveying methods are like green trains. Although they are reliable and suitable for some occasions, they are often unable to cope with long-distance and large-scale conveying occasions due to the limitations of conveying efficiency and speed. For example, although belt conveying can continuously convey materials, its speed is slow and is greatly affected by factors such as terrain and weather.
Manual intervention
Traditional conveying methods usually require more manpower to adjust the flow of materials or repair equipment, which will increase the labor intensity of workers and the operating costs of enterprises. Compared with the automated operation of pneumatic conveying, the traditional conveying system has a lower degree of intelligence and higher maintenance costs.
Large area
Traditional conveying equipment usually takes up a lot of space, such as belt conveyors, which occupy a large area, and the conveying path is relatively fixed and has poor flexibility. In contrast, the pipeline network of pneumatic conveying can be arranged more flexibly to adapt to different production needs.
4. Analysis of the advantages of pneumatic conveying
(1) Improve production efficiency
Pneumatic conveying can greatly improve the material conveying efficiency. Traditional conveying equipment such as belts and screw conveyors are often limited in the material conveying speed and require a lot of manual intervention. Pneumatic conveying, on the other hand, can quickly transport materials to the designated location through the action of airflow, reducing the need for manual operation and thus improving production efficiency.
(2) Strong adaptability
Pneumatic conveying systems can be flexibly arranged to adapt to different production environments and conveying needs. Whether it is long-distance transportation or factory layout in complex terrain, pneumatic conveying can easily cope with it. Compared with traditional conveying equipment, pneumatic conveying can not only cope with more diverse production environments, but also adjust the conveying plan according to production changes.
(3) Reduce maintenance costs
The maintenance cost of pneumatic conveying systems is low, mainly because its equipment has less mechanical wear. Pneumatic conveying transports materials through air flow, avoiding the friction and wear between materials and equipment in traditional mechanical conveying. Therefore, the pneumatic conveying system has a longer service life and a lower maintenance frequency.
(4) Environmental protection and health
Pneumatic conveying systems produce almost no dust during the conveying process, reducing the harm to operators, and are especially suitable for some flammable and explosive materials. Traditional conveying equipment often produces a lot of dust when handling some fine powder materials, posing a threat to the operating environment and personnel health. Pneumatic conveying can not only effectively avoid these problems, but also meet modern environmental protection requirements and reduce environmental pollution in enterprises.
5. Selection guide for pneumatic conveying and traditional conveying
So, in what cases should pneumatic conveying be selected and when should traditional conveying be selected? As an industry expert, here are some of my suggestions:
Efficiency requirements
If the company's production scale is large, the types of materials are diverse, and high-speed and long-distance material transportation is required, pneumatic conveying is undoubtedly a more suitable choice.
Space saving
If the production site space is limited, traditional conveying equipment may not be able to provide flexible conveying solutions, while pneumatic conveying can make full use of limited space through the pipeline network and reduce the floor space.
Environmental protection requirements
If the company has high requirements for environmental protection, especially for the transportation of fine particles, pneumatic conveying will be more in line with the standards than traditional conveying methods.
6. Conclusion: Pneumatic conveying, the high-speed rail of industry
