Particle sizes for the recorded sample and sampling time.
Sample assessment
The melamine record contains two favorable measured timepoints despite an empty summary result field. The procedure itself supplies the outcome evidence. The laboratory test record documents this preparation only; applying the method to another batch requires a matched trial.
Recorded objective
Explore finer powder preparation 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 | 500 mL alumina jar; 450 g of 15–3 mm zirconia balls; 246 g melamine; dry milling; speed setting 480. |
| 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 30 minutes, the sample measured D50 = 23.22 µm and D90 = 40.14 µm. At 1.5 hours, it measured D50 = 17.09 µm and D90 = 30.32 µm. The result field is blank, but both procedure timepoints and percentile pairs are explicitly recorded.
Measured after 1.5 hours for the 246 g melamine charge.
Interpretation
Both reported percentiles decreased between the two measured times. These procedure entries provide a favorable outcome even though the summary result field is empty. They do not establish the minimum achievable size, a maximum size or a reduction relative to unmeasured feed.
Practical precautions
Preserve the sample and media masses and use the same dispersion method when repeating the comparison. Examine powder recovery, temperature and media wear, since none is quantified by the source record.
TENCAN alternatives to evaluate
For follow-up comparison, consider the TENCAN Laboratory Full-Directional Planetary Ball Mill. For melamine, a matched QXQM trial can test whether changing orientation affects the melamine size progression across the two recorded times. 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.
Procedure records XQM; related product is the corresponding tested machine family. Exact variant is not inferred from jar size.
