The shape of the ceramic saddle is through the middle of a hyperbolic cylinder body with a ring bar as its axial cut half, thechemical field professional name is also known as the moment saddle packing.Its size is determined by the diameter of the neck ring.Ceramic saddle is a semicircular structure of open filler,acid and alkali erosion resistance,there is a ring reinforcement in the  middle,to avoid the overlap and shield between the filler,void ratio is large,has good fluid distribution performance,so as to improve the effective utilization of mass and heat transfer,widely used in waste gas purification and gas oxidation RTO and RCO device.
