pneumatic conveyance working principle
- The working principle of a pneumatic conveyor is to use the action of air flow to transport materials from one place to another. It generates airflow by compressing air or other gases to suspend materials in the airflow, thereby achieving fast and efficient transportation. Specifically, the working principle of a pneumatic conveyor is based on the principle of pneumatic conveying. First, air flow is generated by compressed air or other gases to form a certain air flow speed and pressure. Then, the material is sent into the conveying pipe through the feeding device (such as the feeding hopper). The material will be picked up by the air flow, suspended in the air flow, and transported along the pipe with the push of the air flow. Finally, the materials are discharged to the destination through the discharge port.
- The structure of a pneumatic conveyor mainly includes a feeding device, a pipeline system, an air source device, a separation device, a control system, etc. The feeding device is responsible for feeding materials into the conveying pipeline. Common ones include feeding hoppers, rotary valves, etc. The pipeline system is the main channel for material transportation. The air source device provides the necessary compressed air or other gases. The separation device is used to separate materials and gases. The control system is used for automatic control of the entire process.
- Pneumatic conveyors have the advantages of simple structure, easy operation, large conveying capacity, long conveying distance, and high conveying speed. Therefore, they are widely used in plastics, casting, chemical industry, food processing and other industries.

types of pneumatic conveying system
- Pneumatic conveying systems can be divided according to different classification standards, mainly including the following types:
- Divided by conveying pressure: positive pressure, negative pressure, combined positive and negative pressure systems.
- Divided by transportation form: Dilute phase, dense phase, semi-dense phase systems.
- Divided by type: suction type, pressure type, mixing type and circulation type.
- Divided according to the air flow speed in the conveying pipeline: suspension flow and slug flow.
- Divided by sending device: mechanical type and barrel pressure type.
- Divided according to the configuration of the transportation pipe: single pipe transportation and double pipe transportation.
- Divided according to the way of gas source supply: continuous gas supply and pulse gas supply.

What is the meaning of pneumatic conveying?
- The significance of pneumatic conveying is mainly reflected in improving production efficiency, reducing environmental pollution, saving space and reducing costs.
- First of all, pneumatic conveying has the advantages of high efficiency, energy saving, and environmental protection, so it has been widely used in industrial production. With the acceleration of industrialization and the continuous advancement of technology, the application fields of pneumatic conveying are also constantly expanding. In cement, steel, chemical, electric power and other industries, pneumatic conveying has become an indispensable method of material handling. At the same time, with the continuous improvement of environmental awareness, more and more companies are beginning to adopt pneumatic conveying technology to reduce environmental pollution and energy consumption.
- Secondly, pneumatic conveying systems have many advantages. It is easy to maintain, does not require a large amount of mechanical equipment, and the maintenance cost is relatively small. The entire conveying process is carried out in a closed state, avoiding secondary pollution of materials, and is especially suitable for chemical industry, medicine and other industries. In addition, pneumatic conveying systems are less hazardous to operate, can reduce noise and improve the working environment for employees. Compared with traditional mechanical conveying methods, pneumatic conveying systems save space, are suitable for a variety of materials and industries, and can maintain stable and continuous flow during long-distance conveying.
- Finally, pneumatic conveying is of great significance for environmental protection. With the improvement of environmental protection requirements, pneumatic conveying equipment has performed well in applications such as dry ash transportation. It has the characteristics of low wind pressure, simple operation, and low maintenance. It is widely used in electric power, cement, chemical and other industries. The pneumatic conveying system is sealed during the entire conveying process, with no flying dust, effectively reducing environmental pollution.
