Our packing ceramic balls adopt automatic feeding roll forming, which is high hardness, high temperature resistance, high pressure resistance, strong acid and alkali corrosion resistance, good thermal shock stability. Application: Mainly used in high temperature, high pressure and strong corrosive environment in chemical industry. As support materials & packing materials of catalyst in the reactor, it can stand of acid, alkali and other organic solvent corrosion and temperature change in production process. Its main function is to increase gas or liquid distribution points, support and protect less strength activated catalyst. 1.1*1.1*1.2
