Ceramic balls serve as the covering support material and tower packing for the catalyst in the reactor. It has the characteristics of high temperature and pressure resistance, low water absorption, and stable chemical properties. Can withstand corrosion from acids, alkalis, and other organic solvents, and can withstand temperature changes that occur during the production process. Its main function is to increase the distribution point of gas or liquid, support and protect active catalysts with low strength. Classification of ceramic balls: Ceramic balls can be divided into inert ceramic balls, thermal storage ceramic balls and grinding ceramic balls according to their purpose.
The thermal storage ceramic ball has the characteristics of smooth surface, corrosion resistance, high strength, and good thermal storage performance, and is a special filler for air separation heat storage devices. They are all spherical in shape, and thermal storage ceramic balls are used to store heat. They are suitable for preheating forced air in steel plants to achieve rapid heating requirements, and are also used for aluminum melting furnace forging stoves, etc.
Grinding ceramic balls are grinding bodies used for fine grinding equipment such as ball mills, can mills, and vibration mills. Grinding ceramic balls have advantages such as high hardness, high bulk density, and corrosion resistance. Their crushing efficiency and wear resistance are greatly superior to ordinary balls or natural pebbles, and are widely used in industries such as ceramics, glass, enamel, pigments, and chemical engineering.
According to the different AL2O3 content, grinding ceramic balls are divided into silicon carbide grinding ceramic balls, microcrystalline medium aluminum grinding ceramic balls, and high aluminum grinding ceramic balls. Generally speaking, balls with an aluminum content of 60-65% are classified as medium aluminum balls, balls with an aluminum content of 75-80% are classified as medium high aluminum balls, and balls with an aluminum content of over 90% are classified as high aluminum balls. High alumina balls are further divided into 90 porcelain, 92 porcelain, 95 porcelain, and 99 porcelain. Due to its extremely high production costs, 99 porcelain is rarely produced in large quantities by large manufacturers, and currently mainly produced by hand by some special ceramic factories.
