zirconia balls special for grinding machine best grinding medium used in bearing seals
product name:zirconia balls
model:HY-YHG
Product introduction :
Alias zirconia balls, zirconia ceramic balls, zirconium beads, ultrafine grinding media, zirconia beads, zirconia grinding balls, with pearl-like luster and smooth working spherical surface, excellent wear resistance, high processing efficiency.
Zirconia ceramic balls have high strength, high toughness, good wear resistance, high temperature and corrosion resistance, high stiffness, non-magnetic and electrical insulation at room temperature. At 600 degrees Celsius, the strength and hardness of zirconia ceramic balls are almost unchanged. Its density is 6.00g / cm3, and the thermal expansion rate is close to that of metal. It can be used in combination with metal and is suitable for bearings, seals and so on.
1.High grinding efficiency : The specific gravity of yttrium-stabilized TZP zirconia ceramic beads is 1.6 times that of ordinary zirconia beads, and it has higher grinding efficiency under the same conditions.
2.Good fluidity : The product has good roundness, smooth surface, and the wear of the equipment is lower than other grinding media.
Impact resistance, low wear : TZP zirconia ceramic beads have good toughness, no cracking and peeling in high-speed and high-concentration machines, and the wear is only 2 / 1 of zirconium silicate beads.
The use of low cost : the choice of this product will bring you such as media wear, power consumption, labor, equipment and other comprehensive cost reduction, product quality greatly improved.
