Sample assessment
The measured waste-silicon sample was a coarse portion. Other waste-source preparations are mentioned without measurements, so the article keeps the observed sample separate. The laboratory test record documents this preparation only; applying the method to another batch requires a matched trial.
Recorded objective
Record outcomes around the requested 30- and 60-minute preparation periods.
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 stainless-steel jar and standard steel balls; 200 g of the documented coarse sample; 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
The documented coarse sample measured D50 = 5.02 µm and D90 = 16.06 µm after 1 hour. The test record refers to four waste-silicon samples and says the other three were processed as requested, but it supplies no distributions for them and no measured 30-minute endpoint.
Interpretation
The article concerns the measured coarse-sample experiment. Its 1-hour distribution is a useful recorded preparation outcome. The available evidence does not establish matching results for all four samples, or a complete two-timepoint sampling series.
Practical precautions
Keep waste-source identity and sample labels in the private laboratory record. Check steel contamination against the intended silicon analysis and use representative splits; measured results from one waste stream should not be generalized to other streams.
TENCAN alternatives to evaluate
For follow-up comparison, consider the TENCAN Laboratory Full-Directional Planetary Ball Mill. For waste silicon powder, a matched QXQM trial can test whether changing orientation affects the measured coarse waste-silicon portion with representative sampling. 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.
