Particle sizes for the recorded sample and sampling time.
Sample assessment
Jade powder has a three-timepoint record showing a progressively smaller coarse tail. This supports a duration comparison for the supplied powder. The laboratory test record documents this preparation only; applying the method to another batch requires a matched trial.
Recorded objective
Explore the attainable fineness without a fixed numerical target.
Equipment and selection
The recorded planetary machine is XQM. The corresponding TENCAN family is the Vertical square planetary ball mill. The jar volume identifies the test container and does not establish an exact machine variant or production capacity. Equipment association follows the recorded machine designation.
Test setup
| Recorded planetary machine | XQM |
|---|---|
| Documented setup | 100 mL zirconia jar and standard zirconia balls; 17 g powder; dry milling; speed setting 450. |
| Recorded operating cycle | Run 5 / pause 1; units not stated in mode field |
Speed values are reproduced as recorded settings. A rotational unit and planetary-disc versus jar-speed basis are not stated, so these numbers are not labelled rpm.
Recorded procedure and results
At 3 hours the sample measured D50 = 18.38 µm and D90 = 60.81 µm. At 7 hours the values were D50 = 4.19 µm and D90 = 16.71 µm. At 9.5 hours they were D50 = 3.94 µm and D90 = 13.6 µm.
Measured at 9.5 hours for the 17 g jade preparation.
Interpretation
Both reported percentiles decreased through the sampled timepoints. The largest change occurred between 3 and 7 hours; the subsequent change was smaller. These measurements support this recorded fineness progression, without proving that longer treatment would continue to improve it.
Practical precautions
Keep the same dispersion and measurement method throughout a repeat trial. Examine jar and media wear after prolonged milling, and record temperature and recovered mass to assess effects absent from this test record.
TENCAN alternatives to evaluate
For follow-up comparison, consider the TENCAN Laboratory Full-Directional Planetary Ball Mill. For jade powder, a matched QXQM trial can test whether changing orientation affects the jade coarse tail at shorter matched durations. Keep sample mass, media and sampling times controlled. This is a proposed comparison; the test record does not demonstrate a superior result for that alternative. Confirm jar compatibility and the permitted complete loaded mass before selecting a configuration.
