What are ceramic balls used for

Porcelain balls are spherical objects made of ceramic materials, usually made of alumina, zirconia, silicon nitride, silicon carbide and other high-performance ceramic materials. These ceramic materials have many excellent properties that give the ceramic balls unique properties.

Ceramic balls classified by function: 

** Grinding ceramic ball ** : mainly used for grinding media, in the ball mill, vibration mill and other equipment, through the mutual friction and collision with the material, to achieve the crushing and grinding of the material. Grinding ceramic balls need to have high hardness and wear resistance to ensure grinding efficiency and service life. 

** Catalytic ceramic ball ** : as a catalyst carrier, it provides a large specific surface area and good dispersion for the catalyst to promote the chemical reaction. Catalytic ceramic balls usually have a certain pore structure and adsorption properties in order to better load and fix the catalyst. -

** Filled ceramic ball ** : Used to fill in various equipment and structures, play a supporting, fixing, heat insulation, sound insulation and other roles. The performance requirements of filled ceramic balls depend on the specific application scenario, such as the need to have good high temperature resistance in the high temperature environment, and the need to have a certain vibration resistance in the case of vibration.

** Bearing ceramic ball ** : Used to manufacture ceramic bearing roller, with high precision, high speed, low friction, long life, etc., suitable for bearing applications under special working conditions such as high speed, high precision, high temperature, corrosion resistance.

Use of ceramic ball:

1.** Chemical industry ** :  Used as a filler in chemical reactors, towers and other equipment to support, disperse and mass transfer. For example, in the petrochemical catalytic cracking unit, the ceramic ball can support the catalyst, so that the reaction material can be uniformly passed through the catalyst bed, improving the reaction efficiency.

2.** Environmental protection field ** : -In sewage treatment, it can be used as a biofilm carrier to provide a place for microbial growth and reproduction. 3. ** Metallurgical industry ** : -In the metallurgical process, can be used for high-temperature furnace lining materials, such as steel furnaces, iron furnaces, etc. The high temperature resistance and wear resistance of the ceramic ball can withstand the high temperature in the furnace and the erosion of the material, and extend the service life of the furnace.

3.** Machinery industry ** : As a bearing ball or roller, it has the characteristics of high hardness, high wear resistance and low friction coefficient, which can improve the service life and work efficiency of the bearing.

Ceramic ball advantages:

** High hardness ** : The hardness of ceramic balls is much higher than that of ordinary metal materials, such as the hardness of alumina ceramic balls can reach more than 2000 (Vickers hardness). This makes the ceramic ball not easy to be worn and scratched during use, and can maintain a good shape and surface finish, thus extending the service life. In some occasions with high wear resistance requirements, such as bearings, grinding media, etc., ceramic balls have obvious advantages.

** High strength ** : Ceramic material has high compressive strength and bending strength, and can withstand greater pressure and load.

** Low density, lightweight ** : Compared with metal balls, the density of ceramic balls is smaller, such as the density of silicon nitride ceramic balls is almost 1/3 of the bearing steel.

** Good electrical insulation ** : Ceramic materials are good electrical insulators, which can effectively isolate current and avoid problems such as leakage and short circuit.

** Strong corrosion resistance ** : Ceramic ball has excellent corrosion resistance and can resist the erosion of chemical substances such as acid, alkali and salt. In the chemical, petroleum, pharmaceutical and other industries, ceramic balls can be used to transport corrosive media equipment, such as valves, pumps, pipelines, etc., can effectively extend the service life of equipment.

** High temperature stability ** : In a high temperature environment, ceramic balls are not easy to oxidize, decompose and other chemical reactions, and can maintain stable chemical properties.
