Pneumatic conveyor working principle

The working principle of the pneumatic transportation system is based on the principle of pneumatics, which uses compressed air or airflow to form power in the pipeline to promote the movement of materials.
The pneumatic transportation system mainly consists of compression devices, conveying pipelines, control devices, etc. The compression device compresses the air and sends it into the pipeline to form a certain air flow, which pushes the container to move in the pipeline.
At the starting point of the pipeline, the material to be transported is loaded into a container, which is usually cylindrical or spherical to reduce resistance and friction. When the container enters the pipe, the air flow pushes it toward the other end of the pipe. At the end of the pipeline, the container is taken out through the control device to complete the material transfer process.
‌Specific applications of pneumatic transportation systems‌ include applications in hospitals, restaurants, heavy industry, highways, aerospace and other fields.
In hospitals, pneumatic transport systems are used to transport blood specimens, medicines and other items;
In restaurants, used to transport food quickly;
In heavy industry and highway construction, used for rapid transportation of raw materials and materials;
In the field of aerospace, it is used to transport inspection samples, etc.
The advantages of the pneumatic transportation system are that it is efficient, safe, and environmentally friendly. It can significantly increase the transmission speed and efficiency and reduce labor costs‌.

What is pneumatic conveying?

Pneumatic conveying is a technology that uses airflow to transport materials through pipes‌. It uses compressed air to push bulk materials to move in the direction of air flow in the pipeline to realize material transportation. The pneumatic conveying device has a simple structure and is easy to operate. It can convey materials horizontally, vertically or inclined, and can simultaneously perform operations such as heating, cooling, drying and air flow classification during the conveying process.
The working principle of pneumatic conveying is to use the kinetic energy of the air flow to make the bulk materials move along the pipeline with the air flow in a suspended state. According to the direction and pressure of the air flow, pneumatic conveying can be divided into suction type, pressure feeding type and mixed type. The suction type uses an exhaust fan to create a vacuum, so that the material is sucked into the pipeline; the pressure type uses a blower to press air into the pipeline, and the material is transported along with the air flow; the hybrid type is a combination of the above two methods.
Pneumatic conveying has a wide range of applications, including foundry, chemical industry, metallurgy, building materials, grain processing and storage, shipbuilding, machine manufacturing and transportation, etc. Due to its high efficiency, small footprint, economical and environmentally friendly characteristics, pneumatic conveying has become an indispensable technology in many industrial fields.
The advantages of pneumatic conveying include high efficiency, small footprint, economical and environmentally friendly. It can continuously convey loose materials, and the process is closed and is not affected by climate and environment. In addition, pneumatic conveying can also perform multiple process operations at the same time, such as crushing, drying, grading, etc., to improve production efficiency and reduce worker labor intensity.
