China Ceramic Balls
China ceramic ball factories inform us that ceramic balls are mainly classified into two categories based on their applications: packing balls and grinding balls. Of course, there are also niche types such as heat storage ceramic balls. If classified by material, they can be divided into various types such as alumina, zirconia, and silicon carbide ceramic balls. Here, we mainly introduce inert ceramic balls.
Grinding ceramic balls: In equipment such as ball mills, they rely on their high strength and hardness to reduce coarse particle materials to micron or even nanometer levels through mechanical actions like collision, friction, and compression, achieving uniform dispersion. Some special materials can also reduce impurity contamination of the materials, providing qualified raw materials for subsequent production. They are industrial grinding media.
Inert ceramic balls: In reaction towers and absorption towers in the petrochemical and coal chemical industries, they act as support/packing ceramic products due to their “inert” nature of not reacting with the reaction medium, as well as their high temperature resistance, acid and alkali resistance, and high strength. They support catalysts, evenly distribute gas and liquid media, and protect the equipment inside the tower, thereby ensuring reaction efficiency and stable operation of the equipment.
Specification and size
The diameter range of inert ceramic balls is generally between 3mm and 50mm. Common diameter specifications include 3mm, 6mm, 8mm, 10mm, 13mm, 16mm, 19mm, 20mm, 25mm, 30mm, 40mm, 50mm, etc. Other customized size specifications include 1-2mm, etc.

Applications
- In the petroleum refining industry, it is used in catalytic cracking towers and hydrorefining towers to support catalysts inside the towers.
- In the coal chemical industry, it is used in ammonia synthesis towers and methanol preparation reaction towers to support catalysts and assist in the distribution of gas and liquid.
- In the fine chemical industry, it is used in acid-base neutralization towers and solvent recovery towers to evenly distribute acid-base solutions and other media.
- In the environmental protection field, it is used in desulfurization towers and denitrification towers to support desulfurization and denitrification catalysts and protect the internal components of the towers.
- In various gas-liquid separation towers, it is filled in specific areas of the towers to optimize the contact and distribution efficiency of gas and liquid.
- At the bottom or top of tower equipment, it buffers the erosion of high-speed flowing media on the tower wall and distributors, reducing equipment wear.
Classification
Inert ceramic balls, also known as inert alumina ceramic balls, packing ceramic balls, support ceramic balls, catalyst ceramic balls, etc., can be classified according to their appearance and the content of alumina as follows: common ceramic balls, inert alumina ceramic balls, medium alumina ceramic balls, high alumina ceramic balls, 99% high alumina ceramic balls, grooved and perforated ceramic balls, perforated ceramic balls, and microporous ceramic balls.
