💖Product name: 95% zirconia grinding ball
💖High grinding efficiency: The specific gravity of yttrium stabilized TZP zirconia ceramic microbeads is 1.6 times that of ordinary zirconia beads, and has higher grinding efficiency under the same conditions.
💖Good fluidity: product roundness is good, the surface is smooth, and the wear of the equipment is lower than other grinding machines.
💖Impact resistance, low wear: TZP zirconia ceramic microbeads toughness is good, in the high-speed, high concentration of the machine does not crack, peeling, wear only zirconia silicate beads 2/1.
💖Low cost of use: the selection of this product will bring you comprehensive cost reduction such as media wear, power consumption, labor, equipment and so on, and product quality is greatly improved.

وصف

💖Zirconia ball alias zirconia ceramic ball, zirconia ball, ultrafine grinding medium, zirconia microbeads, zirconia grinding ball.

💖Zirconia ball use: especially suitable for vertical stirring mill, horizontal rolling ball mill, vibration mill and all kinds of high line speed rod pin sand mill; Wet and dry ultrafine dispersion and grinding of all kinds of slurry and powder that are required to refuse cross-contamination.

💖Application areas are as follows: A. wear and corrosion resistant products: coatings, textiles, pigments, printing and dyeing; B. High strength, high toughness products: magnetic materials, piezoelectric ceramics, dielectric ceramics; C. Prevention of pollution: medicine, food, cosmetics; D. Ceramics: electronic ceramics, refractory ceramics, structural ceramics

💖Zirconia ball features: high strength and toughness at room temperature, high density, good wear resistance, high temperature corrosion resistance, high stiffness, non-magnetic permeability, electrical insulation, thermal expansion coefficient close to steel and other advantages. When the zirconia ceramic ball is at 600℃, the strength and hardness are almost unchanged. Using yttrium oxide as stabilizer, it is made by special molding process and high temperature roasting and phase fixing process.
