Высокоглиноземный шлифовальный шарик для шаровой мельницы в

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.
