Ceramic ball
Ceramic ball is a kind of ceramic packing material, which is made of high quality kaolin, feldspar material, aluminum oxide material and so on. Inert alumina ball is made of high-quality chemical raw materials processing and clay.
Ceramic ball classification
Alumina ceramic ball
Because of its high strength, high hardness, high wear resistance, large proportion, small volume, high temperature resistance, corrosion resistance, no pollution and other excellent properties, was widely using in the deep processing of thick and hard materials like different types of ceramic, enamel, glass, chemicals and other factories, is ball mill, pot shaped mill, vibrating mill and other fine grinding equipment, grinding body, its grinding grinding efficiency and wear resistance greatly superior to ordinary coccolith or natural pebbles.
(1) the main component of the product is high quality alumina, which has no effect on the quality of the grinding materials.
(2) the product by rolling and pressing, than the major, can greatly improve grinding efficiency and reduce the grinding time, save energy, reduce costs; and effectively increase the effective volume of the ball mill, thereby increasing the adding amount of grinding materials.
(3) the wearing of the product is low, and the service life of the grinding body can be prolonged.
(4) the product has a high degree of whiteness, which will not affect the color of the material being ground.
Two, zirconia ceramic ball
Zirconia ceramic ball zirconia ball has high strength, high toughness, good wear resistance, high temperature resistance, high rigidity, no magnetic conductivity and electrical insulation at room temperature. When the zirconia ceramic ball is 600, the strength and hardness are almost invariable, the density is 6.00g/cm3, the thermal expansion rate is close to that of metal, and can be used with metal joint.
Three, silicon nitride ceramic ball
Silicon nitride ceramic ball is in a non oxidizing atmosphere high temperature sintering precision ceramics with high strength, high wear resistance, high temperature resistance, corrosion resistance, acid, alkali, can be used for a long time in seawater, and is electrically insulating magnetic good performance. At 800 C, strength, hardness is almost unchanged, the density of 3.20g/cm3, almost bearing steel 1/3. weight, the rotation of the centrifugal force is small. Also has the self lubrication, which can be used in the environment without lubrication medium high pollution. Ceramic bearing, mixed ceramic ball bearings of the preferred material.
Four, silicon carbide ceramic ball
Silicon carbide ceramic ball product performance is stable, the silicon nitride comprehensive performance is the best. Compared with steel, the quality is lighter than the steel, the friction coefficient is small, the movement performance
The modulus of elasticity is 50% larger than that of steel, and the coefficient of thermal expansion is less than 25% of steel, which can maintain high strength and hardness, corrosion resistance, no rust, no magnetism, and can work under the condition of no oil lubrication.
