PTFE graphite ball ring is developed on the basis of PTFE Raschig ring. Ball ring is a material with one or two layers of rectangular holes on the side wall. The parent material of the holes does not separate from the side wall but forms inward-bending blades. Although ball rings and Raschig rings of the same size have the same specific surface area and porosity, the small holes on the side wall of the ball ring can be used for gas and liquid circulation, making full use of the inner wall of the ring.
Compared with Raschig rings, ball rings not only have greater production capacity and lower pressure drop, but also have higher separation efficiency and greatly reduced channeling. Ball ring packing is a new type of packing, which is improved by improving some of the main shortcomings of Raschig rings

Compared with Raschig rings, ball rings not only have greater production capacity and lower pressure drop, but also have higher separation efficiency and greatly reduced channeling. Ball ring packing is a new type of packing that is developed to improve some of the main shortcomings of Raschig rings. It is formed by opening six layers of rectangular small windows on the wall of ordinary Raschig rings, with the small window blades overlapping at the center of the ring and the upper and lower layers of windows overlapping each other. The main difference between it and Raschig ring packing is that there are rectangular window holes on the side walls, and the window blades of the window holes are bent into the center of the ring. Due to the opening of the ring wall, the distribution performance of gas and liquid is greatly improved compared with Raschig rings, especially the inner surface area of the ring can be fully utilized.
