Serving device: Manually put the pigging ball at the beginning of the main pipe. The pigging ball pushes the slurry forward in the main pipeline through compressed air.

Receiving Station

　　 Ball collecting device: The inner diameter of the main pipeline is increased to reduce the friction between the pigging ball and the inner wall of the pipeline, so that the pigging ball falls into the ball collecting cart through compressed air and its own weight. The front end of the ball collecting trolley is equipped with a hose to reduce the vibration when the pigging ball falls.
