Alumina ceramic balls: Alumina is the main raw material. According to the content of alumina, they can be divided into medium-alumina ceramic balls (45%-50%), high-alumina ceramic balls (60%-75%), 92 ceramic balls (92% alumina content), 95 ceramic balls (95% alumina content) and 99 ceramic balls (99% alumina content). The higher the alumina content, the better the ceramic balls have high temperature resistance, corrosion resistance and mechanical strength.

Other porcelain balls of materials: such as mullite ceramic balls, cordierite ceramic balls, etc., they have their own unique properties and application fields. Mullite ceramic balls have good thermal shock stability and high temperature strength, and are suitable for high-temperature rapid heating and cooling occasions; cordierite ceramic balls have a low thermal expansion coefficient and can withstand large temperature changes without rupture.

Classified by purpose

Filling ceramic balls: mainly used in reactors, towers and other equipment in chemical, petroleum, natural gas and other industries, and are used as fillers. It can increase the distribution point of gas or liquid, improve the flow state of fluid, improve mass and heat transfer efficiency, and also support and protect active substances such as catalysts.

Grinding ceramic balls: used as a grinding medium in a ball mill, vibration grinding and other grinding equipment, for grinding and crushing various materials. Its high hardness and wear resistance can ensure the grinding effect and improve the fineness and uniformity of the material.

Thermal insulation ceramic ball: has a low thermal conductivity, can effectively reduce the transfer of heat, and play a role in insulation. It is often used in insulation layers of high-temperature kilns, heat treatment equipment, etc. to reduce energy consumption.
