The pneumatic conveying system can be summarized in the simplest terms and can be simply explained as the process of using the pressure generated by compressed gas to move an object from point A to point B. This process can be called a pneumatic conveying system. The pneumatic conveying system is also known as pneumatic conveying. The explanation of pneumatic conveying system in the book is "using the energy of airflow to transport granular materials along the direction of airflow in a closed pipeline, which is a specific application of fluidization technology.

”The main object conveyed by the pneumatic conveying system is dry powder materials, which are transported to the destination through pipeline routing during the conveying process. Due to the simple structure and easy operation of pneumatic conveying system equipment, it can be used for horizontal, vertical or inclined conveying, and can also change the target direction of materials simultaneously during the conveying process. Its energy-saving and environmentally friendly advantages have gained the trust of customers and are widely used in various industries.

According to the density of particles in the conveying pipeline, pneumatic conveying systems are divided into three types: dilute phase conveying, dense phase conveying, and negative pressure conveying. Dilute phase conveying and dense phase conveying belong to positive pressure conveying, also known as pressure conveying pneumatic conveying system. Pressure conveying pneumatic conveying system uses compressed air above atmospheric pressure to push materials for conveying, and moves from high pressure to low pressure with the help of wind pressure. Negative pressure conveying can be understood as suction, also known as suction pneumatic conveying system, which sucks the atmosphere and materials into the pipeline together, and uses low-pressure airflow for conveying. Therefore, it is also known as vacuum suction conveying, which moves materials from low pressure to high pressure direction.

1、 Full utilization of space

The pneumatic conveying system equipment is simple, capable of utilizing factory space reasonably and flexibly, and can bypass obstacles such as large equipment and buildings with the help of pressure pipelines. And it can achieve centralized transportation of materials from multiple points, or dispersed transportation from one point to multiple points.

2、 Wide applicability

The pneumatic conveying system is suitable for continuous conveying of small particle powder materials, as well as intermittent transportation of large amounts of particle materials from equipment such as bulk tankers, railway freight cars, and water cargo ships to storage warehouses.

3、 Closed environment

The transportation route adopts closed pipelines for transportation, which has high safety, low risk of fire and explosion, and can maintain the cleanliness of the factory environment, reducing environmental pollution caused by dust dispersion.

4、 Can achieve long-distance and high-capacity transportation

The pneumatic conveying system can reach a maximum distance of over one kilometer, with a capacity of hundreds of tons per hour. There are only pipelines along the way, which are flexible in layout, do not take up space, and are easy to operate and maintain.

5、 Easy to achieve automation

The operation of equipment such as powder material conveying pumps, flow distributors, and receivers used in pneumatic conveying systems is very similar to that of fluid equipment. Therefore, the same central console can be used for operation, making it easy to achieve automated production.
