1、 Purpose and Characteristics
Ball ring is a rectangular small window with one or two layers along the circumference on the wall of the Rascal ring, and the base material of the small window bends towards the center of the ring and overlaps here. There are windows on the wall of the stepped ring, and there are two layers of cross shaped fins inside the ring, which are staggered at a 45 degree angle. Due to the special structure of the Bao'er ring and the stepped ring, it has the characteristics of low resistance, high efficiency, high operational elasticity, and high porosity, and is currently the preferred packing material for industrial large towers.
