Ceramic Cascade Mini Ring absorbs the characteristics of the ceramic Raschig ring and Pall ring. the tapered flanging on the end of Ceramic Cascade Mini ring is not only reduce air resistance,but also increase air flux. Due to its own asymmetric structure,it will increase the Directional probability when filling. Additionally, also change packing’s contacting way from linear to point. Point contacting provide more contacting area for gas passing, also promote packing’s surface liquid-film renew. Therefore, It is a kind of packing with high mass transfer efficiency.
