Pneumatic conveying technology refers to a conveying technology that uses the force of airflow to produce a one-way flow of animal materials in the pipeline. Roots blowers, vortex blowers, vacuum generators and other equipment are often used as air source devices. So, where did the "gas" go during the pneumatic conveying process.

Most of the "gas" used in pneumatic conveying will be discharged with the material at the terminal discharge port, but not all the gas can go to the end, and some of the gas is consumed in the pipeline, which is often said in our system design : Pressure loss.

1. Pressure loss in horizontal pipelines
In the horizontal conveying pipe, the airflow and the material should move at the same speed. However, due to the friction between the air and the material along the pipe wall during the conveying process, and the mutual friction between the conveying material particles and the particles, a certain amount of friction will occur Pressure loss.

2. Pressure loss in vertical pipes
The material also has a large pressure loss in the vertical conveying pipe. This part of the loss is due to the energy consumption caused by the suspension and lifting of the material.

3. Pressure loss in the elbow
When air and materials pass through the elbow, the direction of movement changes, so the airflow and materials will be more impact and friction at the elbow than in the horizontal and vertical pipes. The pressure loss caused by this friction is compared with the pressure in the horizontal pipe. The loss is even greater.
