Product details

ZrO2 Zirconia Grinding Media
Gongtao company is a leading manufacturer of technical ceramics. Products include both controlled porosity and densely structured ceramics designed to meet requirements specified by our customers for:
Corrosion and wear resistance
With characters of large density, high mechanical strength, high chemical stability, low thermal expansion factor and high abrasion resistance, Zirconia ball is mainly applied as grinding media for various grinding machines. It can provide high grinding efficiency, low noise, pollution free to materials, and long useful life.
Zirconia ceramic is also applied widely as bearing material in traditional bearings of precision machine tool, high-speed electrical machine, automobile, and air conditioner. So, it's applied in industries of petrochemical, chemical, aviation, and navigation.
Strong points: Application:  Size Range  Note:
1. 23% lighter than steel ball, which means less centrifugal force and less friction on the groove during high speed and acceleration. ZrO2 ball is mainly used for valve ball, full ceramic bearing, metering ball, track ball, and precision grinding ball; it can be used in fields requiring chemical resistance, high temperature,electronic insulation,magnetic insulation, non-lubrication. ZrO2 ball is an idea substitute for steel ball in chemical corrosion application. As valve ball, ZrO2 ball is now successfully used in high pressure homogenizer, diaphragm pump, metering pump, oil well pump, high pressure sprayer etc 0.4mm~50.8mm (1/64"~2") with different gauge 1) white color as standard, yellow ZrO2 ball could be supplied upon customer requirement. 2) plenty of stock. 3) non-standard size could be supplied. 4) thermal expansion coefficient of ZrO2 is 10.5*10-6/°C, similar to that of steel, which means ZrO2 has well fitting with metal. However, it also results in larger size change with temperature fluctuation. Also, ZrO2 fractures in rolling-failure, thus it is less stable than Si3N4 in key application.
2. Smaller friction coefficient, more freely rolling.
3. Can be used at higher temperature up to 750ºC.
4. Never rust, and can roll without lubrication.
5. More corrosion resistant than steel
6. No metal contamination.
7. Non-magnetic.
8. Electric isolation.
