2. Hardness: The hardness of the ball should be tested by a Rockwell hardness tester, and the hardness should be within the range of 45-55 HRC.
3. Surface Finish: The rise up finish of the ball should be checked using a surface roughness tester, and the roughness should be inside 0.2μm.
4. Density: The density of the ball should be tried victimisation a pycnometer, and the density should be within the range of 6.5-7.5 g/cm3.
5. Chemical Composition: The chemical composition of the ball should be tested using physical science emission spectroscopy, and the composition should be within the range of 99.2%-99.8% Zr.
6. Magnetic Properties: The magnetic properties of the ball should be tested using a magnetometer, and the magnetic properties should be no more than 0.01μT.
7. Roundness Error: The roundness wrongdoing of the ball should be tested victimisation a dial indicator, and the rotundity should be within 0.02mm.

Use / Maintenance Methods                                                                                                                                      

1. Confirm whether zirconia balls are suitable

The selection of zirconia balls is a key step. Zirconia balls have different hardness, surface smoothness, particle size distribution, abrasion, chemical properties (do not react with materials) and other characteristics. Therefore, appropriate zirconia beads should be selected according to the type and target particle size of the materials you grind and in combination with the target particle size of grinding.

2. Pre-grinding

When using zirconia balls for the first time, it is necessary to put the grinding balls in the slurry with a certain viscosity for pre-grinding for 30 minutes. If the slurry concentration is relatively low, the rotation speed should be reduced, and then the time should not exceed 15 minutes.

3. Cleaning

When grinding paint, it is better to clean the balls with resin. If solvent is needed, reduce the rotation speed, and the time should not exceed 10 minutes. It is recommended to clean zirconia beads intermittently, and then shut down and restart the machine after a period of time.

4. A supplement of zirconia grinding ball

After grinding for a period of time, the balls will collide with each other, which will lead to abrasion of milling balls. Therefore, after using for a period of time, some zirconia balls need to be added as a supplement. Note that the broken balls should be screened off with a sieve before supplement, and then put in zirconia beads with the same weight as the broken ones.

5. Cases when more zirconia grinding balls need to be supplemented

If the grinding time needs to be extended or the grinding fineness can not reach the desired effect when the grinding fineness requirements remain unchanged, a certain amount of grinding balls need to be added.
