Induction

Corundum ceramic balls are widely used in ceramic industrial, glaze, paint, zirconia silicate, aluminum oxide, quartz, silicon carbide, building material, chemical, inks, cosmetics, cement, and other material grinding. Dedicated to providing solutions and creating value for clients according to their specific demands.
90~99% Al₂O₃ grinding balls are widely used in the cement Industry and Mining Industry.

Xinhongji Corundum 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 corundum ceramic balls are made of high-quality solid pressed silicate porcelain with an aluminum oxide content of Al2O3, the alumina is in the range of 90~99%. The corundum ceramic balls have high mechanical strength, resistance to both acid and alkali, some organic solvents, and resistance to thermal shock, which makes them all ideal choices for the 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.

Corundum Ceramic balls come in 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 balls. 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 flow to the next process.

The main materials of our corundum balls are made by scientific formula, molding, and high-temperature calcination. Its maximum refractoriness can reach 1900ºC. It has features of high mechanical strength, long service life, good chemical stability, high-temperature resistance, etc.

Application:

Refractory balls include ordinary refractory balls and high alumina refractory balls. The ordinary refractory ball is suitable for the converter and shift converter of the sulfuric acid and fertilizer industry. High alumina refractory ball is suitable for the hot-blast furnace, heating shift converter, and other equipment of the urea and steel industry.
