Also known as airflow transportation, it is a specific application of fluidization technology to use the energy of airflow to transport granular materials along the airflow direction in a closed pipeline. The structure of the pneumatic conveying device is simple, easy to operate, can be used for horizontal, vertical or inclined direction of conveying, and can also be used in the conveying process at the same time to carry out physical operations or some chemical operations such as material heating, cooling, drying and air flow classification.

China's pneumatic conveying industry network, all pneumatic conveying equipment companies are in it.

Pneumatic conveying can be roughly divided into two types: suction type and pressure feeding type according to the working principle.

Suction pneumatic conveying is to suck the atmosphere and materials into the pipeline together and transport them with a low air pressure airflow, so it is also called vacuum suction.

Pressurized pneumatic conveying is the use of compressed air higher than atmospheric pressure to push materials for transportation.

Pneumatic conveying is mainly divided into two conveying methods, which are divided into dense phase and dilute phase pneumatic conveying. Of course, according to the form used, it can be divided into positive pressure conveying or negative pressure conveying. In addition, there is also a combination of positive and negative pressure and a combination of dilute phase and dense phase pneumatic conveying form.

Pneumatic conveying, also known as airflow conveying, refers to the transportation technology that uses the energy of air to continuously convey powdery bulk materials; Pneumatic conveying equipment is the equipment that uses this technology to convey materials. Pneumatic conveying equipment can prevent materials from being damp and polluted by the outside world; The dust prevention effect is good, which helps enterprises to realize mechanization and automation, and can reduce the labor intensity of workers and save labor costs.

In the process of conveying materials, pneumatic conveying equipment can carry out multiple process operations at the same time, such as: mixing, crushing, sorting, drying, cooling. It has a wide range of applications in petrochemical, casting, metallurgy, building materials, grain processing and other industries.

The pneumatic conveying system is generally composed of feeders (such as pipes, suction nozzles, transmitters, etc.), conveying pipes, air ducts, separators (commonly used volumetric and cyclone), air locks (commonly used as flap type and rotary type, which can be used as both feeders and dischargers), dust collectors and fans (such as centrifugal fans, roots blowers, water ring vacuum pumps, air compressors, etc.) and other equipment and components.

The role of pneumatic conveying equipmentThe function of pneumatic conveying is to make the bulk material pass through the air conveying pipeline, and the flowing conveying air transmits the propulsion force on the bulk material, so that the material can be transported through the conveyor line. There must be a pressure difference between the start and end points of the pipeline during pneumatic conveying, and to overcome this pressure difference, a blower or compressor is required.

The degree of differential pressure depends not only on the length and layout distance of the conveyor line, but also on the concentration and load of bulk materials in the conveyor line.

Advantages: 1. Pneumatic conveying equipment has the characteristics of long conveying distance, large load, simple structure, convenient operation, low noise and low investment. 2. The conveyed material is not affected by the air flow, and the conveyed material has good insulation performance and is not affected by temperature and humidity changes.

3. High conveying efficiency, not easy to be damaged, high safety and reliability, no material pollution, can transport all kinds of powder, and the particle size is not limited. Disadvantages: 1. The particle size of the conveyed material must be small, if the particle size of the material is large, it is easy to block.

2. Due to the physical characteristics of the airflow, the conveying volume is small and there is a certain pressure loss. 3. The maintenance cost of pneumatic conveying equipment is high, and it is necessary to regularly check the cylinder and various components to ensure the normal operation of the equipment.
