Sample assessment
The cured-resin sample has an explicit D90 criterion. Its measured sample time must be distinguished from a much longer separate duration field. The laboratory test record documents this preparation only; applying the method to another batch requires a matched trial.
Recorded objective
Reach D90 at or below the recorded 18 µm objective.
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 | 500 mL zirconia jar with standard 15–3 mm zirconia media; 100 g sample; dry milling; speed setting 580. |
| 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
The named jar was sampled after 16 hours and measured D50 = 7.83 µm and D90 = 15.92 µm. Other portions are described as processed as requested, with no additional size data. A separate test record duration field is 266 hours; it is not tied to the 16-hour measurement and must not be read as that sample time.
Interpretation
The measured jar met the D90 size objective at its documented timepoint. The broad separate duration entry cannot support a milling-rate estimate or a claim about the same endpoint after 266 hours.
Practical precautions
Confirm the duration-field meaning before planning machine occupancy. Monitor temperature and resin adhesion during a repeat, and retain the same analytical dispersion because no temperature or adhesion observations are supplied for this successful endpoint.
TENCAN alternatives to evaluate
For follow-up comparison, consider the TENCAN Laboratory Full-Directional Planetary Ball Mill. For cured resin, a matched QXQM trial can test whether changing orientation affects the cured-resin D90 near its acceptance limit. 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.
