Brief Introduction
Alumina ceramic balls are grinding bodies used in fine grinding equipment such as ball mills, pot mills, and vibration mills. According to the different AL2O3 content, Grinding ceramic balls are divided into silicon carbide grinding ceramic balls, high aluminum grinding ceramic balls, and microcrystalline medium aluminum grinding ceramic balls.The aluminum content of 60%-65% is classified as medium aluminum balls, the aluminum content of 75%-80% is classified as medium-high aluminum balls, and the aluminum content of more than 90% is classified as high aluminum balls. Among them, high aluminum balls are further divided into 90 porcelain, 92 porcelain, 95 porcelain and 99 porcelain.
Rongsheng Alumina ceramic balls have the following advantages:
High hardness: The hardness of alumina ceramic balls is very high, and it is not easy to be damaged even when used in high-speed rotating or vibrating equipment.
High wear resistance: The surface of alumina ceramic balls is smooth and flat, which can effectively reduce wear and extend service life. Its wear resistance is also very good, and it can withstand wear in environments such as high-speed rotation and high-speed friction.
Strong corrosion resistance: The chemical properties of alumina balls are stable, with good corrosion resistance, and are suitable for use in strong acid, strong alkali and other environments.
High compressive strength: Alumina ceramic balls have high compressive strength, are not easy to break or fragment, and can withstand greater pressure.
Good thermal stability: Alumina ceramic balls have good thermal stability, can withstand high temperature environments, and are not easy to deform or melt.
