Inert Alumina Ceramic Balls
Inert ceramic (porcelain) balls are used to fill and support the catalyst layer in catalytic columns and reactors, and as grinding bodies in ball mills.
The balls are made of high quality solid pressed silicate porcelain with an aluminum oxide content of Al2O3 – 23% (in the range of 23-26%). They have high mechanical strength, resistance to acid, alkali, and some organic solvent, and resistance to thermal shock, which makes them all ideal choice for support of all types of catalysts.
Ceramic Balls are available to the order of sizes from 3 mm to 50 mm in diameter. Other types of ceramic products can be made upon your request indicating the necessary technical data.

Inert Alumina Ceramic (Porcelain) Balls Manufacturing:
Production and Application of Inert Ceramic (Porcelain) Balls
- as supporting carriers for catalysts, absorbents, as molecular sieves;
- to fill the reaction apparatus, they act as a distributor of reagents and coolant in the petrochemical and chemical industries;
- as grinding bodies for milling materials in ball mills when grinding and mixing chemicals, pharmaceuticals, dyes, grinding metal surfaces, grinding food raw materials in the food industry.
The balls have extremely low water absorption (real <0.1%), high acid resistance (>99.6%), and a long service life subject to operating conditions.
Porcelain balls are made of silicate (alumina) porcelain by powder compaction of the mass, molding, pulling through the mouthpiece, with diameters ranging from 3 mm to 50 mm. Other types of ceramic products can be made upon your request indicating the necessary technical data.
Products are packed in plastic bags in an amount not exceeding a weight of 30 kg. Transportation in the container is allowed without pallets.

An example of the using of ceramic inert balls to support catalyst in a reactor
Ceramic Balls (also known as support ball, inert ball and catalyst support media) were very important component in the catalytic process in the refinery, gas processing and petrochemical industry.
Its main function is to act as packing material and at the same time to support the catalyst bed in order to prevent breakthrough or loss of catalyst or adsorbent materials downstream of the reactor vessels due to the high pressure and temperature inside the reactor vessels during the operation.
Ceramic ball come up with a few different sizes, which are 1/8", 1/4", 3/8", 1/2", 3/4", 1", 1¼", 1½", 2". The size was arranged layer by layer at the top and bottom of the vessel, with different sizes of ceramic ball.
Chemical reaction in a reactor (designations on the diagram):
- The raw materials flow down from the upper part.
- The raw materials go through the inert balls, to the catalyst area.
- The raw materials chemically react at the catalyst area and get chemically engineering. It becomes the secondary raw materials (products).
- The chemical engineered materials (products) pass through the inert balls and flows to next process.
