Zirconium Oxide Ball for Nano Milling Grinding
product description
The diameter of the grinding medium is related to the particle size of the raw material and the required product particle size. In order to improve grinding efficiency, the particle size of the grinding medium must be greater than 10 times the particle size of the raw material and 200 times the particle size of the final product. Zirconia ceramic grinding ball has a large specific gravity, even a small volume can still ensure high grinding efficiency. High-frequency porcelain abrasives compared with zirconium beads, small proportion, easy to break, not wear-resistant. Zirconia beads have a long service life, the service life of zirconia beads is 20 times that of glass marbles, and it is always crushed into fragments in a small amount, and the zirconia beads without crushing still maintain the original specifications, shape, strength and smooth surface, which can be used in circulation systems. Zirconium beads have high strength, long life, good ductility, low friction coefficient, and can reasonably reduce the frequency of disassembly and refuelling to reduce employee costs. If you want to quickly achieve the mirror effect, the mirror requirements are high, it is recommended to use zirconium beads.
Zirconia at room temperature and pressure has three crystal structures, the first is a cubic phase, cubic phase density 6.27, the second is a tetragonal phase, density 6.1, the third is a monoclinic phase, density 5.65, the three phases at different temperatures, can be converted into each other, monoclinic phase at 1170 degrees Celsius can be converted into a tetragonal phase. The square phase can be converted to the square phase at 2370 degrees Celsius.
